PART ONE

(Opening Doctor Who theme music composed by Keff McCulloch.)
ANNOUNCER: Doctor Who. Survival Of The Fittest, by John Ainsworth and Lee Mansfield. Starring Sylvester McCoy and Tracey Childs. Part One - Klein's Story.

(Walking through forest.)
THE DOCTOR: Here we are.
ELIZABETH KLEIN: The TARDIS?
THE DOCTOR: Yes.
(Door opened. Pulsating sounds of control room beyond.)
THE DOCTOR: After you, Elizabeth.
(Walking inside.)

(Inside the TARDIS control room..)
ELIZABETH KLEIN: Oh. It looks different.
THE DOCTOR: I redecorated.
ELIZABETH KLEIN: I don't like it.
THE DOCTOR: Oh well. It was either this or the leopard-skin.
(Console noises as switches are operated. TARDIS doors close.)
THE DOCTOR: Now, where to take you first, Elizabeth. How about Florana?
(More console sounds.)
ELIZABETH KLEIN: And then what?
(Dematerialisation sound starts.)
ELIZABETH KLEIN: Are we doomed to travel together in the TARDIS forever?
THE DOCTOR: You don't belong anywhere anymore. You've no home for me to take you back to. You're an anomaly.
ELIZABETH KLEIN: An anomaly. That's all I am to you, isn't it? A problem without a solution. You know nothing of my home, of the life I left behind ... those I loved.
THE DOCTOR: You're right. We may be ideologically opposed, we may not trust each other or even like each other, nevertheless, we are now travelling companions, so we need to find a way to co-operate on some level.
ELIZABETH KLEIN: Agreed.
THE DOCTOR: So why don't we begin by you telling me something about the world you left behind? I'm a great believer in talking.
ELIZABETH KLEIN: Why?
THE DOCTOR: I've suggested you have a narrow view of the Universe, you disagree with me. Prove to me I'm wrong.
ELIZABETH KLEIN: All right. What do you want to know?
THE DOCTOR: Well, I confess to being somewhat curious about the events that led you to making your first trip in the TARDIS.
ELIZABETH KLEIN: You already know most of it.
THE DOCTOR: Yes. But you only gave me the potted version. I'd like to know the details.
ELIZABETH KLEIN: Very well, if you really must know.
THE DOCTOR: Yeah. You sit down and relax, and I'll make us a nice cup of tea while I listen. How's that?
(Walking over to fetch tea items.)
ELIZABETH KLEIN: Well ... It was Nineteen Sixty-Two and I was researching Physics at Cambridge when I was suddenly commandeered and was taken aboard a special military airship that would fly me to Berlin. Waiting for me aboard the ship was Major Jonas Faber.

(Pouring liquid. Door opened.)
FABER: Ah, Elizabeth. Come in.
(Door closed. Walking in.)
FABER: Sit down. You don't mind if I call you Elizabeth, do you?
ELIZABETH KLEIN: Please do, Major.
(Chair moved.)
FABER: Please. Call me Jonas. And I trust you will forgive me for not sparing any blushes, but may I say how beautiful you look. Fraya made flesh. Will you take a drink?
ELIZABETH KLEIN: No thank you, Major. I'd rather you just told me what this is all about. What's so special about me that you need to personally travel all the way from Germany to recruit me?
FABER: (laugh.) We have a new project that I am eager to get underway, and ... your skills and experience are particularly suited to it.
ELIZABETH KLEIN: You're very kind, but there are others more qualified than me.
FABER: Oh! Your horizons are about to be broadened, Elizabeth. Broadened beyond the boundaries of the Earth itself.
ELIZABETH KLEIN: Ah, I see. This is some elaborate attempt to get me to give scientific plausibility for the funding of further expeditions to find the spear that penetrated Christ or, the lost Ark of the Covenant or, stranded trolls from Outer Space?
FABER: Let me assure you, I am only interested in facts, not fantasy. Would it surprise you to learn that the Earth has already been visited by extra-terrestrials on several occasions?
ELIZABETH KLEIN: It would surprise me, yes.
FABER: Yet you yourself have speculated on the existence of intelligent beings on other worlds. You are clearly a believer.
ELIZABETH KLEIN: If what you say is true then why have I never heard about this before?
FABER: There would be panic on the streets if the public at large believed they were under threat from alien invaders.
ELIZABETH KLEIN: You still haven't answered my question. What precisely do you want me to do?
FABER: In a Government depository in Berlin are various items of extraterrestrial technology recovered from alien incursions over the years. It will be your task to unlock the secrets of these devices, to further the Reich's cause.
ELIZABETH KLEIN: Why now? If we've known of the existence of aliens for years, why wait until now to begin the research?
FABER: Chairman Hitler was ... shall we say, reluctant to acknowledge the existence of superior alien intelligences. He decreed that all alien artefacts be sealed away and their existence denied. But since his recent death, policies have changed. Hence my assignment to form this new unit. So, Elizabeth, my Fraya. Now you are interested, I'm sure.
ELIZABETH KLEIN: I am certainly intrigued. You know, I think I will have that drink with you, Jonas.

(Walking, Clink of china cups and making tea in the background.)
THE DOCTOR: And of course, it was all true.
ELIZABETH KLEIN: Yes. Once we reached Berlin I was given access to the bunker containing the alien tech. It was incredible. Weaponry, communications devices, the remnants of space vehicles. And not just from one species either, but over a dozen.
THE DOCTOR: You'd be surprised how many visitors your little world has received over the centuries.
ELIZABETH KLEIN: Meeting aliens might be something you do every day, Doctor, but having long-held theories finally confirmed in reality was no small occasion for me.
(Stirring tea.)
THE DOCTOR: And in amongst all this extraterrestrial jetsam and flotsam, you found the TARDIS.
ELIZABETH KLEIN: No, actually. It wasn't until some time later that I discovered the TARDIS. Not until after I'd become much better acquainted with Jonas.

(Moving chair back.)
FABER: Here. Let me refresh your glass.
(Clink of glass. Liquid poured.)
FABER: And then perhaps, another early night for us?
(ELIZABETH KLEIN then FABER laugh.)
FABER: So, any progress on the Dravidian power core?
ELIZABETH KLEIN: No. At least not in the sense that I actually understand it. I can get it to work, I just don't know why it works. And until I do, I can't duplicate it.
FABER: Just imagine. Almost unlimited power for an entire city, all in a device not much larger than a car. It could change the world for ever.
ELIZABETH KLEIN: Perhaps more than you imagine. Don't laugh, but ... I was thinking about the possibility of it eventually being used as a power source for ... well, for time travel.
FABER: Time travel? That's an ... interesting notion. What made you think of that?
ELIZABETH KLEIN: Well ... first there was obviously the utter torment of not being able to relive our first weekend in Paris together over and over again.
(She laughs, FABER laughs.)
ELIZABETH KLEIN: Aside from that, temporal theory has always been of deep interest to me. It's theoretically possible, you know. But it would require a huge amount of energy to achieve. I wrote a thesis on it as part of my studies.
FABER: Yes, I recall.
ELIZABETH KLEIN: Doesn't it strike you as odd that of all the alien species that have visited the Earth that we know of, none appear to have discovered time travel technology?
FABER: Well ... actually...
ELIZABETH KLEIN: Yes?
FABER: There was a time traveller. In fact, he was instrumental in us winning the war.
ELIZABETH KLEIN: What? But that's incredible.
FABER: And also highly confidential. I'm only telling you because I know I can trust you to keep it to yourself.
ELIZABETH KLEIN: Of course. But tell me more.
FABER: In Nineteen Forty-Four, two people from the future, a man and a girl, arrived at Colditz Castle. The girl, Ace, was executed, and the man, known only as The Doctor, escaped in his time machine. But he left behind a small device that contained what we now know as a laser.
ELIZABETH KLEIN: Laser tech came from the future. I knew there was something odd about the speed of that breakthrough, especially considering its importance.
FABER: From the laser we eventually developed nuclear weapons.
ELIZABETH KLEIN: Allowing us to bomb New York and Moscow, forcing the surrender and wining us the war.
FABER: Precisely. To be honest, without those nuclear strikes, things may not have gone so well for the Reich.
ELIZABETH KLEIN: Such a shame that the time machine itself was lost. At least it confirms time travel is possible. How exciting.
FABER: Actually, it isn't lost. We have the machine in the high-security bunker.
ELIZABETH KLEIN: What?
FABER: Stupidly for him, the Doctor returned to Germany ten years later.
(Sound of TARDIS materialisation.)
FABER: His time machine appeared next to a border crossing checkpoint in the West.
(Door opened.)
GERMAN SOLDIER: Halt or I open fire!
FABER: He ignored warnings from the troopers who saw him raise a rifle.
GERMAN SOLDIER: Halt or I fire!
FABER: They gunned him down.
(Shots. Cry.)
FABER: He was killed instantly. The odd thing was though, that when the guards inspected the corpse...
(Walking over.)
FABER: ... they discovered what they believed to have been a rifle was in fact just an old umbrella.
ELIZABETH KLEIN: Curious. But the machine. Why have I not been given access to it along with the other alien technology?
FABER: Elizabeth ... the thing makes me feel ... uneasy.
ELIZABETH KLEIN: Why?
FABER: You have clearly studied the science and theory of time travel, but have you considered the implications of actually using such a machine?
ELIZABETH KLEIN: You mean changing history, I suppose?
FABER: Yes. In the wrong hands, even the smallest interference with past events might result in catastrophic changes to the world we live in today.

(TARDIS control room.)
THE DOCTOR: Jonas was right. Time travelling does carry great responsibilities.
ELIZABETH KLEIN: How hypocritical of you. Considering that you claim that it was your own carelessness that created my time-line.
THE DOCTOR: Even I make mistakes.
ELIZABETH KLEIN: Which is why you came back in Nineteen Fifty-Five, to try and set things right.
(Cup being put down on saucer.)
THE DOCTOR: I wouldn't know about that. For me that hasn't happened.
ELIZABETH KLEIN: If it had you would still be dead. You should be dead.
THE DOCTOR: You're too kind. Anyway, thanks to you Klein, I'm not dead.
ELIZABETH KLEIN: I should have listened to Jonas. If I had I would still be there with him now. Instead it's all gone. Just a memory.
THE DOCTOR: So, how did you convince Jonas to give you access to the TARDIS?
ELIZABETH KLEIN: After Hitler's death in Nineteen Sixty-One, the succeeding ruling body was soon weakened by divisions and internal conflict. A time machine would literally have the power to shape the future, and guarantee the supremacy of the Reich, on Earth and perhaps beyond.

ELIZABETH KLEIN: Just think what we could achieve with a time machine, Jonas. We could avert threats to the stability of the Reich, before they had even occurred.
FABER: In principle it sounds attractive of course. But the risks would be too great. The damage that could be done.
ELIZABETH KLEIN: If operated carefully and responsibly, the risks would be minimal. Do you really want to watch our world destroyed by infighting? The Reich still has enemies. They're just waiting for a moment of weakness to strike. And of course there is the potential threat from aliens.
FABER: I don't know, Elizabeth.
ELIZABETH KLEIN: Those who control such a machine would be held in the highest regard. You and I, Jonas. We could be heralded as the saviours of the Reich. You are a Major now. But with this time machine, you might one day even be the Fuhrer.
FABER: (laugh) That ... that's just a fantasy, Elizabeth.
ELIZABETH KLEIN: Is it? Think about it. At least give me access to the Doctor's machine. Allow me to study it, to understand its operating principles.

ELIZABETH KLEIN: And of course, reluctantly he did. It took some arm-twisting - sometimes literally. Eventually though the TARDIS was exhumed from the secret bunker where it had remained hidden for years, and was brought to my laboratory. My excitement quickly disappeared though when I discovered that I couldn't even gain access to the machine. The door was locked and I had no key. I tried to drill the lock but it was no use.
(Sound inferring a handheld drill in the background)
ELIZABETH KLEIN: High-speed diamond-tipped drills didn't even leave a scratch. However, my attempts to force an entry did activate some kind of distress call. No doubt to alert you had you still been alive to receive it. And then I realised you must have been carrying the key when you were shot. Immediately I requested access to your remains, only to learn that soon after the shooting, your corpse had been stolen.
THE DOCTOR: Stolen, eh? Why, I wonder, would someone want to steal my corpse? I'm much more fun when I'm alive.
ELIZABETH KLEIN: Apparently it was assumed to be trophy-hunters. I dare say that the corpse of a time traveller would make for a rather unique exhibit in an eccentric's collection. Perhaps they had you stuffed.
THE DOCTOR: How flattering.
ELIZABETH KLEIN: So without the key to the TARDIS I had no hope of realising our plans. But it wasn't long before new hope presented itself.

(Electronic burring of trim phone. Walking, lifting of receiver.)
ELIZABETH KLEIN: Hello?
JOHANN SCHMIDT: (phone) Doctor Klein?
(The voice of the eighth Doctor as played by Paul McGann.)
ELIZABETH KLEIN: Yes? Who is this? How did you get this number?
JOHANN SCHMIDT: (phone) Doctor Klein, we need to meet. I have something that I think might be of interest to you.
ELIZABETH KLEIN: Who is this? You have no business phoning here. I can have this call traced.
JOHANN SCHMIDT: (phone) My name is Schmidt. Johann Schmidt. You have in your possession a time machine, do you not?
ELIZABETH KLEIN: What?
JOHANN SCHMIDT: (phone) And I have in my possession the key to that time machine.
ELIZABETH KLEIN: Is this some kind of joke? Is Major Faber behind this?
JOHANN SCHMIDT: (phone) Major who?
ELIZABETH KLEIN: What ... What is it you're after? Money?
JOHANN SCHMIDT: (phone) I'm not interested in money, Doctor. I just want to help you. Meet me at the Cafe Berio in Maschenstrasse at eleven tonight. You'll be quite safe.
(Disconnection.)

ELIZABETH KLEIN: I reasoned that he must be telling the truth about possessing the key - there was no other way he could have known about it. But how did he find me and how did he know I had the TARDIS? I was desperate to gain access to the ship and this seemed to be my only hope so, despite my fears, I decided I would go.

(Raining sound. Opening door of cafe, closing door, walking.)
JOHANN SCHMIDT: Doctor Klein, I presume.
ELIZABETH KLEIN: Johann Schmidt?
JOHANN SCHMIDT: I am sorry to drag you out on a night like this. Sit down, please. Can I get you something to drink?
(Chair moved.)
ELIZABETH KLEIN: No thank you, I didn't come here to socialise.
JOHANN SCHMIDT: No, you came here for this.
(Key put down.)
ELIZABETH KLEIN: That's it. The key.
JOHANN SCHMIDT: Yes. The key to your time machine. Or should I say, the Doctor's time machine.
ELIZABETH KLEIN: How do you know about the Doctor? Where did you get the key ... was it you who stole the Doctor's body?
JOHANN SCHMIDT: (laugh) In a manner of speaking, yes.
ELIZABETH KLEIN: How do I know this is the real key?
JOHANN SCHMIDT: Take it. Try it out. I guarantee it will open the lock.
ELIZABETH KLEIN: You mean ... you're just going to give it to me?
JOHANN SCHMIDT: I am, yes.
ELIZABETH KLEIN: You want nothing in return?
JOHANN SCHMIDT: Nothing.
ELIZABETH KLEIN: I don't understand.
JOHANN SCHMIDT: You are going to do great things with your life, Elizabeth. Marvellous things, and I am offering you my services should you need them. That key will give you access to the time machine, but you will then have to deduce the operating procedures. Could be tricky on your own.
ELIZABETH KLEIN: And what makes you so qualified?
JOHANN SCHMIDT: Qualifications are common, Doctor Klein. What you need is someone with some insight into temporal mechanics. It has been an interest of mine for quite a few years now. I picked up some useful bits of know-how here and there - Copenhagen, other places.
ELIZABETH KLEIN: Even if that's true, why would you want to help me?
JOHANN SCHMIDT: Isn't it obvious? You possess the only known time machine on the planet. For a man with my interests, the chance to examine such a machine is irresistible.
ELIZABETH KLEIN: I see. Well, thank you for the offer. I'll let you know.
JOHANN SCHMIDT: Excellent. I'll be here at the same time next Thursday. See you then, Elizabeth.

ELIZABETH KLEIN: As soon as I got back from my meeting with Schmidt, I tried it. I don't know what I expected to find inside, but not...
THE DOCTOR: Bigger on the inside than the outside.
ELIZABETH KLEIN: Yes, quite. Suddenly I fully appreciated that I was dealing with technology far in advance of our own. If Schmidt really could help I was going to need him.
THE DOCTOR: But you had your doubts about him.
ELIZABETH KLEIN: Of course. He'd more or less admitted to stealing your body.
THE DOCTOR: What did Schmidt look like?
ELIZABETH KLEIN: Young, tall with long dark hair, handsome in a Gothic sort of way. Why do you ask?
THE DOCTOR: Oh, just curious. So despite your reservations, you enlisted Schmidt's help.
ELIZABETH KLEIN: Jonas wasn't happy, of course, but with some persuasion he came to realise that any possibility that Schmidt might help was worth pursuing. So the following week I returned to Cafe Burio, but this time Jonas and an escort accompanied me.

(Walking, opening door.)
JOHANN SCHMIDT: Good evening, Elizabeth. I see you've brought some friends with you.
ELIZABETH KLEIN: This is Major Faber.
FABER: What are you up to, Schmidt?
JOHANN SCHMIDT: I'm not up to anything, Major. I'm only interested in the pursuit of science.
FABER: I find that quite difficult to believe. There's no record of anyone by your name matching your description. However, you have suggested to Doctor Klein here that you might possibly be able to assist her in her researches. I am doubtful of this myself, but it would be foolish of me not to explore all avenues in pursuit of this important work.
JOHANN SCHMIDT: You won't regret it, Major.
FABER: For your own sake, I had better not. Guards, escort this man to the guest quarters that have been prepared for him.
(Chair moved back, seizing and being taken away.)
JOHANN SCHMIDT: Thank you, Major. See you in the morning, Elizabeth, bright and early.
(Door closed.)
FABER: I hope you are doing the right thing, Elizabeth. I don't like him. I feel he is ... almost mocking us. I don't like the idea of him working so closely with you.
ELIZABETH KLEIN: You have taken precautions. I will be fine. If he can help me - and for some reason I believe that he can - we could soon be realising our plans. Come on. Let's go home and drink to our destiny. A destiny we can shape ourselves.

THE DOCTOR: And was Schmidt as helpful as you hoped?
ELIZABETH KLEIN: Yes, he was. We made good progress. He seemed able to make the leap of faith into the unknown that eludes so many scientists. We were of the same mind, I think.
THE DOCTOR: And if I recall correctly from what you told me before, that's when you discovered the TARDIS travel log.
ELIZABETH KLEIN: Yes. We theorised that it should be possible to return the ship to destinations that it had most recently visited. But navigation and independent flight eluded us. Jonas strictly forbade me from attempting any journey until I was confident of being able to pilot the ship back home.
THE DOCTOR: So what finally prompted you to return with the TARDIS to Nineteen Forty-Four?
ELIZABETH KLEIN: Well - now I think about it, it was something that Schmidt said.

(Console room bleeps.)
ELIZABETH KLEIN: That's a negative on test twenty-three. If only we could stumble upon an instruction manual. Even if we did, what are the chances of it being written in German?
(JOHANN SCHMIDT laughs.)
JOHANN SCHMIDT: For all we know, perhaps this panel on the console is a Ouija board!
(ELIZABETH KLEIN gentle laugh.)
JOHANN SCHMIDT: At least then we could ask the Doctor about the vessel's operation from beyond the grave. Such a shame the Doctor was killed.
ELIZABETH KLEIN: That's it. Oh. How can we have been so stupid? The Doctor isn't dead.
JOHANN SCHMIDT: What?
ELIZABETH KLEIN: In Nineteen Forty-Four he's still alive. We know how to access the travel log and return the ship back along its previous flight path.
JOHANN SCHMIDT: Ah, so we could travel back to Colditz in Nineteen Forty-Four, collect the Doctor and force him to explain the operating procedures of his ship.
ELIZABETH KLEIN: Exactly. Yes, that has to be the way.
JOHANN SCHMIDT: That's brilliant, Elizabeth. Now you're beginning to think like a time traveller.

ELIZABETH KLEIN: But Jonas was less enthusiastic.

FABER: Are you out of your mind, Elizabeth?!
ELIZABETH KLEIN: But Jonas, it's the only way.
(FABER sighs.)
ELIZABETH KLEIN: With the Doctor under our control, we could gain access to the time machine's full capabilities...
FABER: No! It is out of the question. Even if you were accompanied by a battalion of storm troopers, there is no guarantee that you would even find the Doctor.
ELIZABETH KLEIN: Of course we would. It's a matter of historical record. We know exactly where and when the Doctor is.
FABER: Even so, he might refuse to assist you even if it meant his own death. Then you would be stranded, trapped in the past, unable to return to the here and now, to me.
ELIZABETH KLEIN: No. The machine's log should record the journey, and we can use it to return here.
FABER: You can't be certain of that. And don't forget that your very presence there would be interfering with the past. A moment in history that could well have been the crucial turning-point in the war. If that laser device was lost or damaged, it could have disastrous consequences.

THE DOCTOR: Jonas was right, wasn't he? As a direct result of your intervention, Ace's CD player and the laser it contained never fell into Nazi hands. Germany lost the war, and history followed its natural course.
ELIZABETH KLEIN: Yes, I know that now, of course. I was so determined to secure a glorious future for the Reich and for Jonas and myself, I took a gamble with Time...
THE DOCTOR: And lost.
ELIZABETH KLEIN: Yes. I would do anything to change the decision that I made next. I could still be there, with him.
THE DOCTOR: We all have to take personal responsibility for our actions. Go on. Finish your story.
ELIZABETH KLEIN: I went back to the lab and dismissed Schmidt's guard, sending him on some fool's errand, then I told Schmidt that we were going to defy Jonas and make the journey anyway.

JOHANN SCHMIDT: You're a brave woman, Elizabeth. I told you you would do great things.
ELIZABETH KLEIN: Straight there, straight back. I have a gun, and even with just the two of us I'm confident we can apprehend the Doctor. We will return to the exact moment that we left. Jonas won't even know we made the trip until we are back.
JOHANN SCHMIDT: Elizabeth, you will have to make this journey alone. I can't go with you.
ELIZABETH KLEIN: But ... why? This is what we've been working towards all along. I need you with me.
FABER: No you don't, Elizabeth.
ELIZABETH KLEIN: Jonas!
FABER: Schmidt, step away from her.
(Walking forwards.)
JOHANN SCHMIDT: Put the gun down, Major. I don't pose any threat to you, I'm only...
(Punch, cry. Body falls.)
FABER: Jonas! What have you done?
FABER: Just after you left my office I finally received an intelligence report on Johann Schmidt. It's not his real name, of course, he has many names. It seems that for several years now he has been assisting political prisoners to escape justice, and has been actively undermining the Reich's ethnic cleansing programmes. Elizabeth, you have been colluding with a traitor and a criminal.
JOHANN SCHMIDT: No, it's not true, Elizabeth, he's just jealous. Jealous of our relationship and our successes. Don't listen to him. Get in the TARDIS and go.
ELIZABETH KLEIN: TARDIS?
JOHANN SCHMIDT: The - the - the time machine.
FABER: No Elizabeth, this man has tricked you. There will be no more time experiments. I'm having this machine taken back to its vault where it can stay forever.
ELIZABETH KLEIN: No Jonas, this is our chance. A chance to take control, to lead, together, at each other's side.
FABER: Don't do it, Elizabeth! I love you. And if you love me you won't get into that machine, it's cursed! I told you it made me feel uneasy.
(Struggle. FABER gasps.)
JOHANN SCHMIDT: Do it, Elizabeth, you have to. Go, you have to!
ELIZABETH KLEIN: I do love you, Jonas. And that's why I must go. Soon you will be Fuhrer.
(Opening door, closing door of TARDIS. TARDIS dematerialisation sound.)

ELIZABETH KLEIN: If only I'd listened to Jonas and not Schmidt.
THE DOCTOR: Perhaps Schmidt saw the bigger picture.
ELIZABETH KLEIN: Like you, you mean. You said TARDIS.
THE DOCTOR: What?
ELIZABETH KLEIN: Just after Jonas shot him, Schmidt called it the TARDIS. I'd forgotten that. It meant nothing to me, I'd never heard that name until I met you. How on earth could Schmidt know it?
THE DOCTOR: The memory cheats. Perhaps your memory's playing tricks with you. I used to think Professor X was better in the Sixties until I went back and watched it again. Even Vault Of The Cyborgs.
ELIZABETH KLEIN: No, I know what I heard. He definitely said TARDIS.
THE DOCTOR: Anyway, it's all in the past now. Well, a version of the past, your past to be precise.
ELIZABETH KLEIN: How could Schmidt have known? Yet another thing to haunt me for the rest of my life. I can't let it go. Somehow I just know that it's important. I can feel it.
THE DOCTOR: Well, if it feels that important to you, then I suppose you should know.
ELIZABETH KLEIN: Know what?
THE DOCTOR: From my point of view, it never happened, but I suspect I know what I planned. Hearing your account confirms it.
ELIZABETH KLEIN: What do you mean? What are you talking about?
THE DOCTOR: My death was no accident. I arranged it. In actual fact, I didn't die at all.
ELIZABETH KLEIN: Ridiculous. You were gunned down, riddled with bullets, nobody could survive that.
THE DOCTOR: Ah - but a Time Lord could. What for a human would be certain death, for me simply triggered a regeneration. My body wasn't stolen. It got up and walked away, literally a new man.
ELIZABETH KLEIN: Regeneration? Surely that's impossible ... What new man?
THE DOCTOR: Young tall, long dark hair, handsome in a Gothic sort of way?
ELIZABETH KLEIN: I think I'm going to be sick. Schmidt? You are saying that Schmidt ... was you?
THE DOCTOR: I'm afraid so, Klein. I apologise for the deception even though I never carried it out. Multiple potential realities make even me giddy.
ELIZABETH KLEIN: Schmidt. You were manipulating me all along. It was all an elaborate trick to make me go back to Nineteen Forty-Four, to change history.
THE DOCTOR: The TARDIS has no travel logs. My future self must have set that up to ensure that you went back to exactly the right point in Space and Time. By working with you he was gently guiding you along, ensuring you made that journey.
ELIZABETH KLEIN: You used me!
THE DOCTOR: Yes. I couldn't make the journey myself, as I would have been crossing my own time track. I really am sorry, Klein. You're a victim of my mistake. But I have a responsibility to repair any damage to the web of Time, particularly when I myself caused that damage.
ELIZABETH KLEIN: All this time, I blamed myself for what happened. My entire world is gone, the people I knew and loved, Jonas, all erased! I thought it was my fault, but really, all along ... I've just been a pawn in this cosmic game of yours.
THE DOCTOR: I'm not proud of my actions, but they were necessary.
ELIZABETH KLEIN: Very well. Fine. That's fine. I understand, Doctor. You clearly did what you thought you had to, you saw the bigger picture.
THE DOCTOR: Yes. Thank you Elizabeth. I must say that's very gracious of you.
ELIZABETH KLEIN: I'm learning, Doctor, like you suggested. Onwards and upwards. What's past is past. We can't risk unravelling the Universe, can we?
THE DOCTOR: No. Maybe I've underestimated you, Elizabeth.
(TARDIS materialisation sound starts.)
ELIZABETH KLEIN: Not to worry. We live and learn, Doctor.
THE DOCTOR: Ah! We've arrived. Your first alien world.
(Walking over. Console sound then doors open with an electronic burring sound.)
THE DOCTOR: Outside those doors lies a whole new perspective for you. You can gaze upon a glittering galaxy your civilisation never knew existed. Let alien sand run through your fingers. Watch strange new life-forms whirling in a different sky.
ELIZABETH KLEIN: I can't wait. I simply cannot wait.

PART TWO

(Opening Doctor Who theme music composed by Keff McCulloch.)
ANNOUNCER: Doctor Who. Survival Of The Fittest, by Jonathan Clements. Starring Sylvester McCoy and Tracey Childs. Part Two.

(TARDIS materialisation sound. Door opens. Walking out.)
ELIZABETH KLEIN: Oh. A cave.
THE DOCTOR: Yes. A cave. But you sound disappointed.
ELIZABETH KLEIN: Well, it's not the most exciting location that the TARDIS has taken us.
THE DOCTOR: Remember Klein, things aren't always as they seem.
ELIZABETH KLEIN: A cave doesn't really compare to the crystal plains of Mondroxia.
THE DOCTOR: Or the floating ocean of Quinbrax Four.
ELIZABETH KLEIN: Or even the mercury swamps of Vulcan.
THE DOCTOR: Yes. Sorry about your boots.
ELIZABETH KLEIN: Mm.
(Walking.)
ELIZABETH KLEIN: But you're right. Who knows what we'll find here.
THE DOCTOR: Maybe travel is broadening your mind.
ELIZABETH KLEIN: All thanks to your education, Doctor?
THE DOCTOR: It's quite a nice cave, don't you think? I wonder. I wonder if there's an ... (Shouting) Echo!
(His voice echoes.)
ELIZABETH KLEIN: I'm having a look outside in the vain hope that there is something remotel... Doctor.
THE DOCTOR: What? What is it, Klein?
ELIZABETH KLEIN: The sky.
(Running over.)
ELIZABETH KLEIN: Look at the sky.
THE DOCTOR: What of it, Klein? It's night. Just a bunch of stars. Seen one, seen them all.
ELIZABETH KLEIN: There is a whole galaxy in the sky.
THE DOCTOR: There's a whole galaxy in every sky, Klein, if you only had the eyes to look.
ELIZABETH KLEIN: Not like this. Not like that.
THE DOCTOR: We are a long way from Earth. We are in a system high above the galactic plain, that gives us a view of the whole Milky Way.
ELIZABETH KLEIN: It's beautiful.
THE DOCTOR: Oh a mundane little galaxy, really. Nothing much to write home about.
ELIZABETH KLEIN: Oh, shut up Doctor, it's fantastic.
THE DOCTOR: Yes. It's a big Universe, Klein, and there's so much to see.
THE WATCHER: Watching. Watching. Watching. Waiting and watching.
THE DOCTOR: Hello. What are you?
ELIZABETH KLEIN: What is it, Doctor?
THE DOCTOR: Well, it's certainly local.
(Buzzing.)
ELIZABETH KLEIN: A real live alien.
THE DOCTOR: Well, technically Klein, we're the aliens here. See how travel broadens the mind.
ELIZABETH KLEIN: Do you recognise the life-form?
THE DOCTOR: Some sort of insectoid.
ELIZABETH KLEIN: It's bigger than a cat.
THE WATCHER: Someone is here. Someone is here. Someone is here...
(Voice fades away. THE DOCTOR/ELIZABETH KLEIN laugh.)
THE DOCTOR: Well, there you are. First contact.
ELIZABETH KLEIN: What was it?
THE DOCTOR: Some sort of threshold guardian, I'm guessing.
ELIZABETH KLEIN: A doorkeeper?
THE DOCTOR: A butler-fly, you might say.
ELIZABETH KLEIN: What?
(THE DOCTOR exhales through his lips.)
THE DOCTOR: I think we need to work on your sense of humour.
ELIZABETH KLEIN: It tells the inhabitants that we've arrived?
THE DOCTOR: Whoever lives in this network of tunnels, Klein, will know we've arrived soon enough.

(Buzzing past with noise fading up at start then fading down as it buzzes off.)
THE WATCHER: Someone is here. Someone is here. Someone is here. Someone is here. Someone is here. Someone is here...

(Sniffing.)
THE DOCTOR: Can you smell that?
(Sniffing.)
ELIZABETH KLEIN: Yes. Yes I can.
THE DOCTOR: Almost overpowering.
ELIZABETH KLEIN: What is it?
(Sniffing.)
THE DOCTOR: Ammonia, perhaps. No. Sawdust.
ELIZABETH KLEIN: Sawdust? I thought it was more like iron filings.
(Sniffing.)
THE DOCTOR: Freshly-laid carpet with just a...
(Sniffing.)
THE DOCTOR: ... a hint of strawberries.
ELIZABETH KLEIN: You would be great fun at a wine-tasting.
THE DOCTOR: I'll have you know I'm great fun everywhere.
ELIZABETH KLEIN: But what is the smell? Where is it coming from?
THE DOCTOR: It's a scent, a signal, left behind by the ... butler-fly.
ELIZABETH KLEIN: What does it mean?
THE DOCTOR: I expect Klein that it means, "someone is here, someone is here, someone is here!"
ELIZABETH KLEIN: Now I know you have gone mad.
THE DOCTOR: I think the natives communicate through scent.
ELIZABETH KLEIN: No they don't. I heard it with my own ears, shouting out in perfect German at the top of its voice.
THE DOCTOR: It had no vocal chords. You only thought you heard that.
ELIZABETH KLEIN: I was sure of it.
THE DOCTOR: The TARDIS has a special ability, remember. It makes all languages intelligible within a limited radius around it.
ELIZABETH KLEIN: So you said in Kenya.
THE DOCTOR: Even languages that are composed solely of scent-markers, you're hearing words that aren't there, and this residual smell is - I suppose it's like an accent.
ELIZABETH KLEIN: What a shame it doesn't work properly.
THE DOCTOR: Excuse me?
ELIZABETH KLEIN: If your TARDIS worked properly I wouldn't smell a thing, and you wouldn't have such a stuffy Prussian accent.
THE DOCTOR: I think the creature we met was so loud because that was its entire function.
ELIZABETH KLEIN: To shout that someone has arrived?
THE DOCTOR: Yes.
ELIZABETH KLEIN: Specialisation?
THE DOCTOR: Yes Klein, very good, yes.
ELIZABETH KLEIN: These aliens have specialised roles. Small ones to watch and warn...
THE DOCTOR: Perhaps medium-sized ones to work and build.
ELIZABETH KLEIN: But Doctor...
THE DOCTOR: What?
ELIZABETH KLEIN: If they're truly like insects on Earth...
THE DOCTOR: Will there be giant ones to fight and protect?

THE VRILL: Repel intruder ... repel intruder ... repel intruder ... repel intruder ... repel intruder ... repel intruder...
THE WATCHER: Watching. Watching. Waiting and watching. Nobody. Nobody.
THE CARRION: Kill the intruders.
THE WATCHER: Waiting and watching.
THE CARRION: Kill the intruders.
THE WATCHER: Approaching.
THE CARRION: Kill the intruders.
THE VRILL: This is the Carrion. The Carrion approaches.
THE CARRION: Kill the intruders.
(THE VRILL voices agitated while THE CARRION continues to chant "Kill the intruders.")

THE VRILL: Distress. Distress.
THE CARRION: Kill the intruders. Kill the intruders. Kill the intruders.

THE VRILL: Repel intruders ... repel intruders ... repel intruders...
(The chanting of these words continues.)
ELIZABETH KLEIN: We must leave the cave before they arrive.
THE DOCTOR: They will repel intruders, Klein, but we're friends. I shall tell them that.
ELIZABETH KLEIN: I don't trust you. Why should they?
THE DOCTOR: I imagine that if one communicates by smell, it leaves very little room for anything but the statement of facts.
ELIZABETH KLEIN: What? Doctor, they're the size of cars.
THE DOCTOR: No sarcasm, no jokes, no lies either, I'll bet. All they can do is speak the truth.
ELIZABETH KLEIN: Doctor, they are huge. They will tear us apart.
THE DOCTOR: We mean you no harm. We mean you no harm.
(THE VRILL stop chanting "Repel intruders.")
LILLY: You are friends?
THE DOCTOR: We are. Hello.
ROSE: Friends. Safety.
(ELIZABETH KLEIN cough.)
ELIZABETH KLEIN: Can you smell that?
THE DOCTOR: Yes I can. Honey. I-is it honey?
ELIZABETH KLEIN: They are rather ... gullible.
THE DOCTOR: Trusting, Klein. Don't hold it against them. Their language offers no leeway for anything that is not true. Allow me to introduce myself. I'm the Doctor.
LILLY/ROSE: The Doctor? The Doctor. The Doctor.
THE DOCTOR: And who might you be, two brave little soldiers?
ELIZABETH KLEIN: Less of the little, Doctor, they could snap us in two.
ROSE: Hello, the Doctor. We are the...
(Chittering sound.)
ELIZABETH KLEIN: What the hell was that?
THE DOCTOR: They have no word for what they are saying. We only have the smell.
LILLY: Why does it not respond?
ROSE: I think our language is new to them.
ELIZABETH KLEIN: I smell forests. I smell...
THE DOCTOR: Dust moats in warm sunlight.
ELIZABETH KLEIN: What on earth does that smell like?
THE DOCTOR: That's the image I'm getting.
ELIZABETH KLEIN: But it's not a word, is it?
LILLY: We are the...
(Chittering sound.)
THE DOCTOR: Then pick one, make one up.
ELIZABETH KLEIN: All right. Vrill. That smell is Vrill.
ROSE: We are the Vrill.
LILLY: We are the Vrill.
ROSE/LILLY: We are the Vrill. We are the Vrill.
THE DOCTOR: And are there only two of you?
ROSE: Half of half of eight. All that now remains of eight times eight times eight times eight.
ELIZABETH KLEIN: What about the little butler-fly?
LILLY: She means the Watcher.
ROSE: Three. We are among the last of the fertilised eggs. Our function's already chosen. Two workers, and one watchman.
LILLY: And one other.
THE DOCTOR: So four, then. Any advance on four?
ROSE: Some died. Some eggs are still to hatch. But no more to be laid.
LILLY: The Doctor, the sent of your name is one of helping, healing information. Is this true?
THE DOCTOR: Yes it is.
LILLY: Help us. Help us against the...
(Chittering sound.)
THE DOCTOR: The what?
LILLY: The... (chittering sound) ... that approaches.
ELIZABETH KLEIN: I'm getting ... Oh! Is that rotting flesh? Decay?
THE DOCTOR: Carrion? The Carrion is coming. What is that?

THE CARRION: ... Kill the intruders. Kill the intruders. Kill the intruders. Kill the intruders.
(THE CARRION growls.)
LILLY: It approaches.
ROSE: The Carrion has been driven mad.
LILLY: It wanders the nest.
ROSE: It kills everything that it finds.
THE DOCTOR: Lucky for us that we're standing at the exit.
ELIZABETH KLEIN: You're right. Let's just leave the nest.
LILLY: We can leave the nest? We can flee the nest?
THE DOCTOR: Of course. Quickly now. Chop-chop.
LILLY: We must not.
THE DOCTOR: Of course you can. There's a whole forest out there. Come on everybody, follow me.
ROSE: Follow the Doctor?
THE DOCTOR: Come on. What are you afraid of?
LILLY: The Winterlack. The Winterlack will kill us.
ELIZABETH KLEIN: What is this ... Winterlack?
THE DOCTOR: It can't be worse than the Carrion.
ROSE: It is. It is.
ELIZABETH KLEIN: Doctor, I don't know about you, but ... these creatures are big enough to take on a tank. If they are more scared of something outside the nest...
THE DOCTOR: Yes Klein, I see your point. Tell me, where do these passageways lead?
LILLY: All lead to the hatching yard.
THE DOCTOR: The centre of your nest?
ROSE: Yes. It is where we hatch.
THE DOCTOR: I gathered that. And what is at the centre?
LILLY: The Authority.
ELIZABETH KLEIN: Doctor, in dealing with any native people, or alien race, I imagine, it is best to converse with the upper levels of the command structure.
THE DOCTOR: Very well, my new insectoid friends. Before this Carrion arrives ... take me to your leader.
(THE CARRION roars.)
THE CARRION: Kill the intruders. Kill the intruders. Kill the intruders. Kill the intruders. Kill the intruders.

(Walking forwards.)
THE DOCTOR: Do the Vrill have names?
ROSE: We do not have names. Only jobs. Workers and Warriors and Watchers and Cleaners and...
THE DOCTOR: All right, all right, yes. Do you mind if I give you names?
LILLY: Can you do that, Doctor?
THE DOCTOR: Yes. One of my many talents.
ELIZABETH KLEIN: Doctor, is this wise? There might be some sort of ... well, cultural dissonance.
THE DOCTOR: Not like you to worry about rocking the boat, Klein. Right, since smell is what we go on, that's what we're going to use.
(Sniffing.)
THE DOCTOR: Right. You my girl, you're called Rose.
ROSE: I am Rose.
THE DOCTOR: And you, the younger one, you are...
(Sniffing.)
THE DOCTOR: Lilly.
LILLY: I am Lilly.
(Roar.)
ROSE: The Carrion.
LILLY: It's reached the atrium.
THE DOCTOR: Then we'd better keep moving. Come on, ladies.
ELIZABETH KLEIN: What is this Carrion?
ROSE: One of us.
LILLY: Yet not one of us. Corrupted.
THE DOCTOR: The Carrion is a Vrill?
ROSE: Its wings in tatters, its shell cracked and oozing.
LILLY: Its fighting claws are broken from killing fresh hatchlings, from smashing at the nest walls.
ELIZABETH KLEIN: Doctor, it's a warrior.
THE DOCTOR: So it seems. A Warrior Vrill. Damaged in some way and driven mad. Which means we must split up.
ELIZABETH KLEIN: What? Why?
THE DOCTOR: Rose, take Klein down that passage, I'll go down this one with Lilly.
ELIZABETH KLEIN: Doctor, there is strength in numbers.
THE DOCTOR: Not if we're evading a Vrill predator.
ELIZABETH KLEIN: Why?
THE DOCTOR: Shout with a human voice in these caves and you leave an echo. Communicate with scent...
ELIZABETH KLEIN: And you can be tracked.
(Sniffing.)
THE DOCTOR: It's all here - everything we said, everything we talked about. It's all lurking around here in the air.
(Echoing speeded up voices of THE DOCTOR's earlier conversations with the Vrill - his scent.)
ELIZABETH KLEIN: Which is why we must split up, confuse the trails. Doctor, you are very smart.
THE DOCTOR: I know.
ELIZABETH KLEIN: You would have been such an asset to the Party.
THE DOCTOR: Such a sweet thing to say, Klein. Now, move!

(Confused Vrill voices.)
THE VRILL: I cannot ... Distress ...
THE WATCHER: They cannot ... of unknown manufacture. Danger. Danger. Danger. I cannot see. I cannot see. I cannot see. Call the warriors! Call the Warriors! Distress. Distress.
(Walking forwards.)
THE VRILL: (multiple voices) I am stunned. Why am I stunned? ... We are under attack ... We are under attack ... Let me through ... We are under attack ... Let me through ... I cannot...

THE DOCTOR: Did you say something, Lilly?
LILLY: Not I.
THE DOCTOR: The smell in here is ... ooh! Awful. It's ... It's a dead Vrill.
LILLY: Many dead. So many dead. We must move them to get through.
THE DOCTOR: So many bodies. Looks like they jammed the passageway. Er, let me help, here.
LILLY: Lift.
(Struggling to move objects. THE DOCTOR sighs.)
THE DOCTOR: Wh-what happened here, wh-what...?
(Faint voices of THE VRILL.)
THE DOCTOR: Wait.
LILLY: What is it, Doctor?
THE DOCTOR: I can hear them. I can hear the dead.
LILLY: Their last distress signals remain...
THE VRILL: We are under attack...
LILLY: ... in the air.
THE DOCTOR: Yes, yes, I... I can just...
THE VRILL: We are under attack...
THE DOCTOR: There was an attack of some sort, they ... burned? Choked?
LILLY: It was the Winterlack.
THE DOCTOR: But what is a Winterlack? When you say that I just get the smell of impending snowfall and pine needles.
LILLY: The Winterlack.
THE DOCTOR: Whatever it is you don't really have a word for it, and it killed everything in your nest. All of the adults.
LILLY: I hatched after the disaster.
THE DOCTOR: What incredible creatures you are. So much of your character, so much of your memory is hardwired into you. It's there before you are even born.
LILLY: We hatch ready to labour. We perform our tasks. We follow the Authority.
THE DOCTOR: Yes, I see that. You're waiting for orders. Hah! I bet Klein would like that. You're just following orders.

(Walking forwards. Bubbling.)
ELIZABETH KLEIN: Oh my word. This must be the hatching yard.
ROSE: It is. We have arrived before the Doctor. His path must have been blocked by the dead.
ELIZABETH KLEIN: Doctor? Doctor, can you hear me? We've made it to the centre of the nest.
THE DOCTOR: (off) We're still a way off yet, Klein. Don't do anything stupid.
ELIZABETH KLEIN: Doctor, it's amazing.
THE DOCTOR: (off) I'm sure it is.
ELIZABETH KLEIN: It's vast. And at the centre a great boiling lake. And I can see eggs. I see Vrill eggs in the water.
ROSE: This way. There is a safe path down. You have no wings.
ELIZABETH KLEIN: Yes, I see it. Thank you, Rose. So the eggs are all down there?
ROSE: The eggs sit in the boiling nutrients. They harden until it is time for them to hatch, then we take them from the shallows and wait for the new Vrill to come forth.
(Tapping.)
ELIZABETH KLEIN: And these are the shards of a Vrill egg?
ROSE: They are the shards of my egg. I hatched here not long ago.
ELIZABETH KLEIN: They're ... they're tough. Too tough for me to break.
ROSE: We Vrill are stronger than you.
ELIZABETH KLEIN: (laughing) Yes, you must be. What on Earth?
ROSE: What is it? Have you found something?
ELIZABETH KLEIN: Yes I have, Rose. Yes I have.

(Moving objects aside to pass.)
LILLY: Nearly done, Doctor.
THE DOCTOR: So many dead and no clue how they died.
LILLY: I cannot help you, Doctor. I was not even born. It was the Winterlack.
THE DOCTOR: Winterlack, yes. Which means nothing. You're afraid of Winter, cold? But these caverns are stuffy and hot. No. No, the cold didn't kill them.
(THE DOCTOR grunts.)
LILLY: We should throw the dead outside, but there are too many.
THE DOCTOR: I ... I just want to ... to get a look at this dead Vrill. You don't mind, do you?
(Large heavy insect body rolled over.)
THE DOCTOR: Hmm?
LILLY: Have you found something, Doctor?
(THE DOCTOR calls LILLY Rose by mistake)
THE DOCTOR: Well Rose, it's more about what I'm not finding, you see ... Well, maybe you can't. But whatever killed your predecessors didn't hurt them. There's no sign of physical struggle, no wounds, no broken limbs, it's like ... whatever killed them just made them all curl up and die, in their thousands.

ELIZABETH KLEIN: Rose, where does this tunnel go?
ROSE: I do not know.
ELIZABETH KLEIN: You know the rest of this place like the back of your ... claw. Why not this tunnel?
ROSE: I have not seen it before.
ELIZABETH KLEIN: I'll bet you haven't. It's straight. This has been drilled by a machine.
ROSE: What is a machine?
(Moving metal component.)
ELIZABETH KLEIN: Well, for a start, this is.
ROSE: It is not of Vrill manufacture.
ELIZABETH KLEIN: No it isn't. This is a drill bit. Looks to me as though it's a self-powering robot drill, designed to slice through into your nest from the surface.
ROSE: It made the tunnel?
ELIZABETH KLEIN: Yes Rose, it made this tunnel.
ROSE: The Winterlack?
ELIZABETH KLEIN: Well, if by Winterlack you mean an outside agency that massacred the entire nest, then yes. I'm guessing this is what it is.
ROSE: This is what killed my forebears?
ELIZABETH KLEIN: No. No. This is what killed them.
(Metal container moved aside.)
ROSE: Also not of Vrill manufacture.
ELIZABETH KLEIN: This is a canister of ... Oh. Well, now it's a canister of nothing. When this drill smashed into the centre of your nest ... ah. As I thought.
ROSE: You can tell all these things because you are a questioner.
ELIZABETH KLEIN: No, I can tell these things because I can read. Here, on the side.
ROSE: I see nothing.
ELIZABETH KLEIN: Well, I suppose you wouldn't. There are marks on the side here.
ROSE: What do they mean?
ELIZABETH KLEIN: They say, Spear of destiny, Two Tri C Eighty-One. Not for civilian use. Hazardous. Five Series Nerve Agent. And then a whole lot of information about how dangerous it is.
ROSE: We are in danger?
ELIZABETH KLEIN: No. No, the danger is past. This canister is empty. If it's anything like the nerve gases that I know of, this is deadly for a few hours, but ... well, it breaks down into its component chemicals within a couple of days.
ROSE: How do you know this?
ELIZABETH KLEIN: Because this is a human weapon, Rose.
ROSE: What is a human?
ELIZABETH KLEIN: I am. It seems that I am one of the Winterlack.
ROSE: Distress! Distress! Distress!
ELIZABETH KLEIN: Rose?
ROSE: Distress!
ELIZABETH KLEIN: There's no need to be so...
ROSE: Distress! Distress!
ELIZABETH KLEIN: Rose...
ROSE: Distress!
(ELIZABETH KLEIN gasps.)
ROSE: Distress! Distress!
ELIZABETH KLEIN: Rose...
ROSE: Distress, distress, distress...
ELIZABETH KLEIN: Put me down! Rose!
ROSE: Distress, distress...

(THE VRILL voices, mixed in with the voice of ELIZABETH KLEIN.)
ROSE: Distress.
ELIZABETH KLEIN: I am one of the Winterlack.
ROSE: Winterlack is here. Winterlack in the hatching yard.
ELIZABETH KLEIN: I am one of the Winterlack.
ROSE: Cast out the intruder. Cast out the Winterlack.
ELIZABETH KLEIN: I am one of the Winterlack.
ROSE: Distress.
THE VRILL: Distress.
ROSE: Distress. Distress...
THE VRILL: The Winterlack is here...
ROSE: The Winterlack is here.
THE VRILL: Winterlack in the hatching yard.
ROSE: Winterlack in the hatching yard.
ELIZABETH KLEIN: I am one of the Winterlack.
THE VRILL: Cast out the intruder.
ROSE: Cast out the intruder.
THE VRILL: Cast out the Winterlack...

ELIZABETH KLEIN: I am one of the Winterlack.
THE DOCTOR: What's that noise?
LILLY: A distress signal. The Winterlack has returned.
THE DOCTOR: No, no, that's not right.
LILLY: The signal is very clear.
THE DOCTOR: No, that's Klein's voice. I ... I'm sure you're quoting her out of context. Klein! Klein!

ELIZABETH KLEIN: Put me down. Put me down!
ROSE: I shall remove the Winterlack from the nest. The unknown tunnel leads straight to the surface.
ELIZABETH KLEIN: Let go of me, Rose. You're hurting me.
(Buzzing.)
THE DOCTOR: (off) Klein! Tell her she's got it wrong.
ELIZABETH KLEIN: She won't listen.
THE DOCTOR: (off) The distress signal must be overwhelming her. Rose, can't you see what you're doing? Rose, don't go out into the open. Remember the Winterlack.
ROSE: Cast out the Winterlack.
THE DOCTOR: Klein! Wait for the wind. Do you hear me? Shout in the wind.
ELIZABETH KLEIN: Doctor. Doctor!
THE DOCTOR: Klein!
ELIZABETH KLEIN: (faint) Doctor!
LILLY: Doctor, you were with the Winterlack. Are you also Winterlack?
THE DOCTOR: I mean you no harm, Lilly. I'm your friend. I'm like you. We can help each other.
LILLY: You are not the Winterlack?
THE DOCTOR: No, I'm not.
LILLY: You are our friend.
THE DOCTOR: That's right. I am.
LILLY: Rose has cast out the Winterlack.
THE DOCTOR: Well, er ... Difficult to know where to start with this one.
LILLY: The signal was clear. There was a Winterlack. It gave us a Winterlack signal.
THE DOCTOR: Yes, I can see that when the signal is really loud and you pass it on, when the smell is overpowering, then you just act without thinking.
LILLY: It is for the good of the nest.
THE DOCTOR: But not for the good of Klein. Oh, I do hope she's all right.
(Noise of metal.)
THE DOCTOR: Wait, wait, Lilly. What is that? Put it down, there's a good girl.
(Metal rattle. Walking over to it.)
THE DOCTOR: Lilly? Where did you get this?
LILLY: Here in the hatching yard. It was the creation of the Winterlack.
THE DOCTOR: Nerve gas. So that's what the Winterlack are.
LILLY: The Winterlack are outside the nest, in the forest.
THE DOCTOR: Yes. And now so is Klein.

(Buzzing. Electronic bleeping.)
JACKSON: Jackson to base.
STEFFEN: (communicator) Steffen receiving, over.
JACKSON: I've got a contact. Target is no longer airborne, repeat, target is no longer airborne.
STEFFEN: (communicator) Take it out. Kill it.
ROSE: Winterlack, Winterlack...
JACKSON: What on...
(Machine gun bursts. Buzzing fades away.)
JACKSON: Target in retreat. It flew off. Over.
ROSE: Distress. Distress. Distress...
JACKSON: Did you say something, Steffen?
STEFFEN: (communicator) Negative.
ROSE: Distress. Distress. Distress...
JACKSON: Must be hearing things.
STEFFEN: (communicator) Oh, forget about that. There must be others out there. Keep scanning.

THE AUTHORITY: Distress. Distress.
THE DOCTOR: Now, that's a weird signal. Faint, but still strong.
LILLY: It is the last signal of the Authority.
(Moving body.)
THE DOCTOR: I think this is your Authority, Lilly. The signal is strongest here, near this body.
LILLY: This is where the Authority should reside.
THE DOCTOR: Centre of the nest. It makes sense. Poor old girl. This must be her. Or what's left of her.
THE AUTHORITY: Distress. Distress...

(Bleeping of scanner.)
JACKSON: Jackson to base.
STEFFEN: (communicator) Go ahead.
JACKSON: I've got zero motion. That must have been the only target. Over.
STEFFEN: (communicator) Maybe. If you scared it off that's good for us. Maybe these are the last ones left alive. Runts of the litter or something.
JACKSON: Yeah, I guess so.
(Faster bleeping.)
JACKSON: Something on the scope.
STEFFEN: (communicator) Reload, you idiot! Take it out, Jackson!
JACKSON: Aye-aye, sir.
(Approaching person.)
ELIZABETH KLEIN: Don't shoot. Don't shoot.
STEFFEN: (communicator) Jackson? Sit rep, over.
JACKSON: Who the hell are you?
ELIZABETH KLEIN: Who the hell are you?
STEFFEN: (communicator) Jackson, please respond!

STEFFEN: Jackson, respond.
JACKSON: (communicator) There's someone here.
STEFFEN: What? Who?
JACKSON: (communicator) A woman.
STEFFEN: A human?
JACKSON: (communicator) She was very ... unhappy to see what we'd done to the xenomorphs. She's, well, she's demanding to see you, sir.
STEFFEN: Ah, Geo-Police.
(Banging fist down twice)
STEFFEN: Dammit! Dammit!
JACKSON: (communicator) Jackson to base. Please advise.
STEFFEN: Fine, Jackson. Bring her back to the ship. Tell her I look forward to meeting her. Base out.

THE AUTHORITY: Distress ... distress ... distress ... distress...
LILLY: Is the Authority functioning?
THE DOCTOR: No, Lilly. She was killed along with all the others. Her last signal was still in the air after many days.
LILLY: Killed by the Winterlack.
THE DOCTOR: Yes. The nerve gas got them all, including the Authority. Hmm. Does the Authority lay the eggs?
LILLY: Yes.
THE DOCTOR: And there is only one Authority?
LILLY: Only one Authority.
THE DOCTOR: Then the only eggs that are left are the ones like yours, the ones that she laid before the attack. How many of those are there?
LILLY: I cannot say for sure.
THE DOCTOR: Take a guess.
LILLY: Not many.
THE DOCTOR: Oh dear.
LILLY: Perhaps only eight times eight times eight times eight.
THE DOCTOR: What? That's ... that's more than four thousand eggs left to hatch. The place is going to be crawling with worker Vrill.
LILLY: No. Most of the remaining eggs were unfertilised. There will be no more like me. Just me now, if Rose does not return.
THE DOCTOR: Hmm ... There's something ... something I'm missing. You Vrill aren't quite like bees but your life-cycle is similar enough.
LILLY: I do not understand.
THE DOCTOR: Er - no Lilly, don't worry, just left me think, let me think, let me think ... I've known plenty of beekeepers, haven't I ... I should have listened, I mean, Aristotle never stopped wittering on about them, and ... I was stuck in a tea party with Thomas Jefferson and he wouldn't shut up about them. Now ... Aha! Lilly...
LILLY: What is it, Doctor?
THE DOCTOR: Bees can make a new queen to make new eggs. C-can you do that? I mean, can you make a new Authority?
LILLY: We require an Authority to order the correct nutrients. Without an Authority, we cannot make another one.
THE DOCTOR: Hmm ... Oh Lilly, you poor, poor thing. The Winterlack really have wiped you out. You might be the last of your kind.

(Walking through forest, then stopping.)
ELIZABETH KLEIN: That's not a very big ship.
JACKSON: It's big enough. There's only two of us now.
(Walking out of ship.)
ELIZABETH KLEIN: And yet you took on an entire race. Impressive.
STEFFEN: Hello. My name is Steffen. Pleased to meet you.
ELIZABETH KLEIN: What are you doing on this planet? Who the hell are you?
STEFFEN: Dismissed, Jackson.
JACKSON: Sir.
(Walking away.)
STEFFEN: Perhaps I should be asking you the same question.
ELIZABETH KLEIN: My name is Klein, that is all you need to know. How did you get here? Why are you here? Why are you shooting the Vrill?
STEFFEN: Hey, hey, easy now. Come aboard, one question at a time. We have nothing to hide from the Geo-Police. I have every respect for your work.
(Walking.)
ELIZABETH KLEIN: I see. Good. Then you can start by telling me about the nerve gas.
STEFFEN: Oh. You know about that.
ELIZABETH KLEIN: I saw it with my own eyes.
STEFFEN: You've been inside the nest?
ELIZABETH KLEIN: Yes I have. And thanks to your nerve gas, I was forcibly ejected as well.
STEFFEN: You were there when we drilled through?
ELIZABETH KLEIN: No, you idiot! I was there to witness the aftermath. And the Vrill were so confused they thought I was you and threw me out.
STEFFEN: Look - the what? Why are you calling them Vrill?

LILLY: Doctor, the Carrion has reached the hatching yard.
THE DOCTOR: Fine. Let's put a stop to this. Come on.
LILLY: No Doctor, we must flee. You are walking towards it.
THE DOCTOR: Absolutely, Lilly. I'm going to make friends.
LILLY: It will not listen. It never listens.
THE DOCTOR: It's a Vrill warrior, right? It's one of you. When I tell you I'm your friend, you believe me. The Carrion will too.
LILLY: Doctor, we must flee, or it will kill us. It only knows killing.
(THE CARRION roars.)
THE DOCTOR: Crikey. Klein was right.
LILLY: Doctor, this way.
THE DOCTOR: I mean you no harm. I mean you no harm!
(Creature roars.)

PART THREE

(Opening Doctor Who theme music composed by Keff McCulloch.)
ANNOUNCER: Doctor Who. Survival Of The Fittest, by Jonathan Clements. Starring Sylvester McCoy and Tracey Childs. Part Three.

LILLY: Doctor, we must flee, or it will kill us. It only knows killing.
(THE CARRION roars.)
THE DOCTOR: Crikey. Klein was right.
LILLY: Doctor, this way.
THE DOCTOR: I mean you no harm. I mean you no harm!
(Creature roars. THE DOCTOR cries as though being thrown aside by the creature.)
LILLY: It doesn't work, Doctor. It can't hear you. It only sees an enemy to be destroyed.
THE DOCTOR: I can smell the honey. I know my signal's being transmitted. Why won't it respond?
LILLY: It has never responded. It broadcasts signals, but never receives.
THE DOCTOR: The nerve gas. Of course.
(Creature roars. Rushing off.)
THE DOCTOR: Quick, Lilly, it's coming back. In the shadows - hide among the eggs.
(Creature roars.)

(Bleeping instrument panel.)
ELIZABETH KLEIN: That xenomorph you were shooting at had a name, you know. She was called Rose.
STEFFEN: Oh. Okay. Friend of yours?
ELIZABETH KLEIN: We had a little misunderstanding, that much is true, and - yes, she did intend to kill me.
STEFFEN: So I expect you'll want to thank us for saving you.
ELIZABETH KLEIN: No I will not. I talked her out of it.
STEFFEN: Her?
ELIZABETH KLEIN: The scent signals were overpowering, but the Doctor was right. Out in the wind, out in the breeze they blew away.
STEFFEN: This is all a bit far fetched...
ELIZABETH KLEIN: I talked her out of it. Do you see, I talked her out of it. She set me down safely in the forest.
STEFFEN: Right, and what does this have to do with me again?
ELIZABETH KLEIN: You were shooting at her like a bunch of cowboys. You scared her off again. And it's a long walk back through the forest to the nest entrance.
STEFFEN: Honestly Madam, you are talking and words are coming out of your mouth but I have no idea what you are saying.
ELIZABETH KLEIN: I didn't think so.
(Moving door open.)
ELIZABETH KLEIN: Come with me to the forest.
STEFFEN: I don't take orders.
ELIZABETH KLEIN: Come with me, now.

LILLY: It will find us. We are too close.
THE DOCTOR: It won't hurt the eggs. It's only trouble is with, well, anything else that moves.
LILLY: What do you mean?
THE DOCTOR: The Carrion hatched first. It's the oldest surviving Vrill. It must have hatched while the gas was still in the air.
LILLY: This gas is the Winterlack weapon?
THE DOCTOR: Yes, no wonder you've been able to evade the Carrion for so long. It hasn't been on our trail at all. It's been wandering the corridors at random. It can only go on what it sees.
(Fluttering noise.)
THE DOCTOR: Lilly?
LILLY: Yes, Doctor?
THE DOCTOR: There's something alive inside this egg.
(More fluttering sounds.)

(Bushes being moved aside as they walk through the forest.)
ELIZABETH KLEIN: So tell me Steffen, what are you doing injecting nerve gas into the centre of the Vrill nest?
STEFFEN: You appear to know quite a lot about these aliens.
ELIZABETH KLEIN: These aliens as you call them are the native species on this planet, and one that you humans are busy exterminating.
STEFFEN: It's kill or be killed on this planet. Creatures like your friend are why we are now down to just two of us.
ELIZABETH KLEIN: This is the place. This is where they had their little encounter. See the broken branches, the scuffed earth?
STEFFEN: So what? The native life-forms are dangerous.
ELIZABETH KLEIN: The native life-forms are terrified, of you. Did you try communicating with them?
STEFFEN: (laugh.) I don't have time for this. Come back with you...
(Struggle. STEFFEN cries out.)
STEFFEN: Let ... let go of me!
ELIZABETH KLEIN: If a headlock's what it takes ... Now, down on your knees.
STEFFEN: I'm warning you, Klein.
ELIZABETH KLEIN: Warn away. Smell the ground.
STEFFEN: You've got to be kidding.
ELIZABETH KLEIN: I am deadly serious. Tell me what you can smell.
STEFFEN: Er...
(Sniffs.)
STEFFEN: Burning toast? That's weird. Why do I smell burning toast?
ELIZABETH KLEIN: Go on.
STEFFEN: Er ... carpet? Lilies, maybe.
VRILL VOICE: Distress...
STEFFEN: Did you say something?
ELIZABETH KLEIN: No Steffen, I did not.
VRILL VOICE: Distress. Distress.
ELIZABETH KLEIN: Now can you hear it?
STEFFEN: What's going on?
ELIZABETH KLEIN: The Vrill communicate by scent markers. When you shot this one she put clouds of invisible pheromones into the air.
STEFFEN: Saying "distress."
ELIZABETH KLEIN: Saying "help me." Saying "why are they hurting me?" Saying "danger."
STEFFEN: How can I hear it if it's communicating by smell? What the hell's going on here?
ELIZABETH KLEIN: Just trust me. Right now you and the Vrill will be able to understand each other. You'll hear their signals as words and they will hear your words as...
STEFFEN: Smells? This is ludicrous. This is utterly ludicrous.
ELIZABETH KLEIN: Really? I've just proved it to you, haven't I?
STEFFEN: But ... How come I've never noticed this before? Oh! Oh, I get it. Is this some sort of Geo-Police experiment?
ELIZABETH KLEIN: I ... I am not authorised to discuss classified matters.
STEFFEN: That's why this world is closed off. You're experimenting with some sort of xeno communication deal here.
ELIZABETH KLEIN: Had it occurred to you that this world is closed off because it is not possible to communicate with the natives?
STEFFEN: But now it is possible? How did this happen? Why can I suddenly hear what they're saying?
ELIZABETH KLEIN: The whole forest will talk to you, if you'd just use your nose.

THE DOCTOR: Lilly, I thought you said the eggs wouldn't hatch.
LILLY: I said that there would be no more Vrill like me.
(Fluttering.)
THE DOCTOR: What's this one? This one is trying to get out. The egg is so huge that I can only imagine...
LILLY: It is a Warrior Vrill, Doctor.
THE DOCTOR: And when a Vrill hatches, is it ready for anything? Awake, adult?
LILLY: That is correct.
THE DOCTOR: Then that's what we need. A Warrior Vrill on our side.
(Tapping on egg shell.)
LILLY: It has not yet hatched.
THE DOCTOR: It's knocking on the egg. It's trying to get out.
LILLY: Yes, Doctor. Hatching is imminent.
THE DOCTOR: Then let's help it.

STEFFEN: Typical Geo-Police. Barging in wherever you feel like it, claiming to represent the interests of indigenous life-forms.
ELIZABETH KLEIN: Since you're killing them off you clearly don't care yourself. I don't care who's the inferior race here, I care that there is an entire alien civilisation that can be studied.
STEFFEN: Please, Klein. If you were from the Geo-Police we can ... work something out.
ELIZABETH KLEIN: Can we?
STEFFEN: We're not invaders, we're colonists.
ELIZABETH KLEIN: There are only two of you. How long do you expect your new society to endure?
STEFFEN: Obviously, Klein, we are the advance party, the other colonists will come after us.
ELIZABETH KLEIN: Once you've wiped out the dominant species on this planet.
STEFFEN: The Vrill are dangerous. They attacked us.
ELIZABETH KLEIN: Would that be before or after you invaded their world and started shooting at anything that moved?
STEFFEN: Klein, my home world is drastically overcrowded. It was never intended for long-term habitation.
ELIZABETH KLEIN: What's your point?
STEFFEN: The air is dirty. The food is getting more toxic by the day, there's no privacy, no nature. My home world is a slum.
ELIZABETH KLEIN: So find another.
STEFFEN: Which brings me here.
ELIZABETH KLEIN: This planet is taken. Look up in the sky, Steffen, there is an entire galaxy there.
STEFFEN: This world is the nearest and the best for us. We need the ... What's the word?
ELIZABETH KLEIN: Lebensraum.
STEFFEN: I'm sorry?
ELIZABETH KLEIN: Living space. You've bred like rabbits and taken everything you can get from your home world, and now you want to take it from everyone else.
STEFFEN: (laugh) You make us sound like we're the bad guys.

(Banging.)
THE DOCTOR: Come on, crack, open!
LILLY: Doctor, what you are doing is not ordained.
THE DOCTOR: If it saves our lives, it's ordained enough for me.
LILLY: The egg must hatch itself. Without aid, it will hatch in time.
THE DOCTOR: Time is one thing we don't have, Lilly, I need something to cut the outer membrane. Ah yes.
LILLY: What is that? It looks Winterlack.
THE DOCTOR: No Lilly, it's just the key to my TARDIS, just a key.
LILLY: What does it do?
THE DOCTOR: It opens things. Come on, Lilly.
LILLY: It is not ordained.
THE DOCTOR: Help me open this egg, if you want to live.

STEFFEN: We just don't have the resources to search further out for a suitable inhabited world, not without help, but you Geo-Police won't do that, will you?
ELIZABETH KLEIN: Won't we?
STEFFEN: No. You'll interfere. You'll tell us where we can go, where we can't go, but if we don't meet your requirements for civilisation you won't actually help us.
ELIZABETH KLEIN: Ah - unternecht. I shall enjoy mentioning this to the Doctor.
STEFFEN: What?
ELIZABETH KLEIN: You are - if you will forgive me Steffen - you are an inferior race. The Geo-Police will not help you. You must help yourself.
STEFFEN: Your big non-interference policy cuts both ways, Klein. You mark my words. If you ever find yourself in a tight spot and in need of my help...
ELIZABETH KLEIN: Yes?
STEFFEN: I'll be sure not to interfere while some alien life form eats you alive.

(Noises of trying to open the egg.)
THE DOCTOR: Right now, Lilly, we just need to open the membrane, that's all. There.
(Buzzing.)
BUTTERFLY: I am alive. I am ready. I am ready.
THE DOCTOR: Good. We need your help.
BUTTERFLY: I am reporting for duty.
THE DOCTOR: We are in danger.
BUTTERFLY: Are you The Authority?
THE DOCTOR: No, I - I'm a friend. Tell it, Lilly.
LILLY: The Doctor is our friend. The Carrion is trying to kill us.
BUTTERFLY: Is the Carrion our enemy?
THE DOCTOR: Sadly it is, and we cannot stop it.
BUTTERFLY: I am a Warrior Vrill. I shall protect you.
(Growl of THE CARRION.)
LILLY: Doctor, the Carrion approaches.
THE DOCTOR: Come on, Lilly.
BUTTERFLY: Protect the Vrill.
THE CARRION: New intruder detected.
(Buzzing.)
LILLY: Doctor, why are we not running? Now is our chance.
(Buzzing.)
THE DOCTOR: Because it's over, Lilly. It's already over.
LILLY: But there is still danger.
THE DOCTOR: The Carrion had given everything it could. It was already weakened. This new hatchling only has to deliver the killing blow.
(Buzzing, thudding as though attacking THE CARRION.)
BUTTERFLY: Protect the nest.
THE CARRION: Kill the intruder. Distress. Distress.
(Fall, thud.)
THE CARRION: Alarm.
LILLY: The Carrion is gone?
THE DOCTOR: Yes, Lilly. Poor thing.
LILLY: You mourn an enemy?
THE DOCTOR: Was it really our enemy, Lilly? It didn't stand a chance born in agony, its wings malformed, its senses dulled, all alone in the nest.
LILLY: It tried to kill us.
THE DOCTOR: Yes Lilly, but only because it grew up alone and friendless, unaware of any other Vrill, thinking that everything it saw, even a fellow Vrill, was an intruder.
LILLY: I think I understand.
THE DOCTOR: That was why it had to die.
(Buzzing as Butterfly flies back to them.)
BUTTERFLY: The Carrion is defeated. I await orders.
THE DOCTOR: Thank you, my protector. Thank you for saving us.
BUTTERFLY: I protect the nest. It is my duty.
THE DOCTOR: I suppose we need a name for you too. Hmm. You are a beautiful creature. The Carrion's wings were never quite developed, maybe damaged in a dozen battles, but yours - yours are magnificent.
(Buzzing.)
THE DOCTOR: Butterfly.

STEFFEN: Just one Vrill is strong enough to tear apart a platoon of armed soldiers.
ELIZABETH KLEIN: This is a military operation.
STEFFEN: This is pest control.
ELIZABETH KLEIN: These are not rats in a barn, they are sentient creatures.
STEFFEN: How do you know?
ELIZABETH KLEIN: I pay attention, which is more than you have done if you hadn't been listening to what the Vrill are broadcasting.
STEFFEN: That is, admittedly, a new development.
ELIZABETH KLEIN: New? It is the beginning of a new epoch. Don't you see? Now you can talk to the Vrill. You can negotiate with them.
STEFFEN: Somehow I don't think that's going to work.
ELIZABETH KLEIN: But you won't even try?
STEFFEN: It's survival of the fittest, Klein. We are the master race here.
ELIZABETH KLEIN: I ... Oh.
STEFFEN: Are you all right?
ELIZABETH KLEIN: Yes. Yes ... Well ... it's been a while since I heard that term, I ... I never really expected to hear it from ... someone else.
STEFFEN: Humanity is the inheritor of Nature, its master, its warden. We should be able to treat is as we please.

ROSE: Sister, can you hear? Lilly, are you there? There is no signal from the Carrion. Somewhere in the nest, the Carrion has been defeated.
BUTTERFLY: Find the one called Klein. Find the one called Klein. Searching for the one called Klein.
ROSE: Something approaches. Welcome, new hatchling. Welcome to the nest.
BUTTERFLY: Find the one called Klein. Find the one called Klein.
(Buzzing past.)
BUTTERFLY: Searching for the one called Klein.
ROSE: Where are you going? Why are you heading outside? Under what authority? Who commands you?

ELIZABETH KLEIN: So this is how a colonial operation works, Steffen. Two men in a ship full of weapons grade chemicals drop out of the sky, kill off the locals, and everything's ready for the settlers.
STEFFEN: You sound surprised. You must have seen things like this before.
ELIZABETH KLEIN: There are still Vrill left alive, you know.
STEFFEN: I know, and nerve gas isn't cheap.
ELIZABETH KLEIN: So how do you know when they're all dead and it's safe for you to move in?
STEFFEN: There'll be a few stragglers hatching after the attack, but they won't last. We wait to see no movement on the readouts.
ELIZABETH KLEIN: The readouts?
STEFFEN: Behind you.
(Turning round. Bleeps of instrument.)
ELIZABETH KLEIN: This ... is an image of the Vrill hive. I can see all the passages.
STEFFEN: Yes. We've put GI physics units in a grid for a three-mile radius.
ELIZABETH KLEIN: So this is live?
STEFFEN: Yes. We can't really get much in terms of life readings, but we can get the tunnels and the major heat sources.
ELIZABETH KLEIN: I'm seeing one heat source, one huge heat source right here at the centre.
STEFFEN: That's the heart of the nest.
ELIZABETH KLEIN: The hatching yard?
STEFFEN: There's some sort of isotope or volcanic extrusion at the lowest point of the nest.
ELIZABETH KLEIN: Yes, there's a huge underground lake of boiling nutrients that incubates the eggs.
STEFFEN: How about that.
ELIZABETH KLEIN: You didn't know? You know enough about the Vrill's social structure to gas their entire nest, but you don't know how their nest works?
STEFFEN: Our camera gave us what we needed to know. Eggs in the hatching yard along with nutrient pods, thousands of them - although without any Vrill workers to tend to them, I guess they're just sitting around now.

(Bubbling sound nearby.)
LILLY: Now what do we do, Doctor?
THE DOCTOR: I sent Butterfly to find Klein and bring her back safe.
LILLY: If she is still alive.
THE DOCTOR: She will be, if she listened to me.
LILLY: What did you tell her to do?
THE DOCTOR: I told her to ... Well, Lilly, these Vrill orders - they overpower you when you're all yelling together, but out in the open, the signal strength dissipates quite fast.
LILLY: Oh, I see.
THE DOCTOR: Besides the Vrill's idea of removing a danger is simply to throw it out of the nest. Klein will be somewhere in the forest, I imagine, but Lilly...
LILLY: Yes, Doctor?
THE DOCTOR: Butterfly saved our lives, but why was there a warrior egg down here that was ready to hatch in the first place?
LILLY: To make a worker, the correct nutrients must be added on the order of the Authority.
THE DOCTOR: And if there is no authority?
LILLY: Then the eggs remain in their default condition.
THE DOCTOR: Ah. Now I understand. Oh dear. We're going to have to warn them.
LILLY: Who?
THE DOCTOR: Everyone.

(Electronic alarm.)
STEFFEN: Incoming airborne mass reading. It's twice the size of your friendly neighbourhood Vrill. Lock and load.
ELIZABETH KLEIN: Wait. Wait, Steffen!
STEFFEN: No time for this now, Klein.
ELIZABETH KLEIN: Don't shoot, what are you doing?
STEFFEN: Base to perimeter. Sit rep, over.
JACKSON: (intercom) Target is on a south-easterly trajectory.
ELIZABETH KLEIN: South east?
STEFFEN: Yes, south east. Wait. What?
ELIZABETH KLEIN: It's not heading for your base, it's not attacking you at all. It's scanning the terrain. It's looking for something.

THE DOCTOR: Lilly, I have to leave the nest and get down the hill to the forest. I have to get to Klein. And the Winterlack if necessary.
LILLY: It is a long climb down the mountainside. Can you not fly?
THE DOCTOR: Well, in a manner of speaking, Lilly. Only a fool would walk all the way down the mountain through the forest. No, I can get down there in my TARDIS.
LILLY: In your what?
THE DOCTOR: Er, the blue box. It will take me. I can just nudge it a few miles to the south and re-materialise. Yes.
(Patting his pockets.)
LILLY: What is the meaning of this strange dance?
THE DOCTOR: It's not a dance, Lilly, it's erm ... I can't seem to find my ... Have you, er ... seen the key to my TARDIS anywhere?

STEFFEN: (communicator) Jackson, the xenomorph appears to be moving away from the base.
JACKSON: What? No way.
(Bleeps of scanner.)
JACKSON: It's turning back again. It's definitely making sweeps of the area. It's getting closer again.
STEFFEN: (communicator) Do you have a clear sight line?
JACKSON: I'll try. It's tough to get a lock on.
STEFFEN: (communicator) I don't care. Get it out of my sky!
JACKSON: Roger that. It's coming this way. Nearly there.
STEFFEN: (communicator) Shoot it down, Jackson!
(Buzzing. Shots.)
JACKSON: Damn.

(Buzzing.)
BUTTERFLY: Find the one called Klein. Find the one called Klein. Searching for the one called Klein.

JACKSON: (communicator) What the hell is that voice?
STEFFEN: What voice, Jackson? What voice?
ELIZABETH KLEIN: Did it talk to him? Was it putting out a signal?
STEFFEN: What voice, Jackson!
JACKSON: (communicator) It's like a message. It's really loud. Can't you hear it? Keeps saying "Find the one called Klein."
ELIZABETH KLEIN: It's looking for me. Give me a radio.
(Trying to take radio.)
STEFFEN: Hey, those aren't cheap. You can't talk to it on a radio.
ELIZABETH KLEIN: It's so I can talk to you, stupid. It knows my name, it's looking for me. I'm going outside. The Doctor must have sent it.
(Walking off.)
STEFFEN: Who?
(Opening door, closing door.)
STEFFEN: Klein? Come back. You'll get yourself killed! Well. Every cloud has a silver lining.

(Trudging downhill.)
THE DOCTOR: Oh, only a fool. Me and my big mouth. Fool indeed.
(Shots fired.)
THE DOCTOR: Hey! Don't shoot at it!
(Shot fired.)
THE DOCTOR: What are you idiots doing?
(Shots fired.)
THE DOCTOR: Klein! Klein!
(Shots fired.)
THE DOCTOR: If you're down there ... Oh, what's the use.
(Shots fired.)

(Door opened, running down ramp.)
BUTTERFLY: Find the one called Klein...
ELIZABETH KLEIN: Hey!
BUTTERFLY: Find the one called Klein...
ELIZABETH KLEIN: Hey, Vrill in the sky, I am Klein.
BUTTERFLY: Searching for the one called Klein...
ELIZABETH KLEIN: I'm the one called Klein. Over here!
(Shots fired. Erratic buzzing.)
BUTTERFLY: (weakly) Find the one called Klein ... find the one called Klein ... Distress. Distress.
ELIZABETH KLEIN: You found me. I'm here.
BUTTERFLY: (weakly) You are Klein?
ELIZABETH KLEIN: Yes. Yes I am.
BUTTERFLY: (weakly) I am Butterfly. Distress. Distress. Alone.

STEFFEN: Did we get it?
ELIZABETH KLEIN: (communicator) Yes, Steffen, you got it.
STEFFEN: Good.
ELIZABETH KLEIN: Not really. It must have been working for the Doctor. Nobody else would call a Vrill warrior Butterfly.
STEFFEN: (communicator) What?
ELIZABETH KLEIN: Butterfly.
STEFFEN: (communicator) Who is this Doctor you keep talking about?
(Walking over.)
THE DOCTOR: Oh, that would be me.
ELIZABETH KLEIN: Doctor. I can't believe it.
THE DOCTOR: That I made it down the hill?
ELIZABETH KLEIN: That I'm actually pleased to see you.
STEFFEN: (communicator) Klein? Are you there? Please respond.
THE DOCTOR: Oh, likewise Klein, I'm sure. Oh no. Aw. My poor little Butterfly. What have they done to you?
ELIZABETH KLEIN: They shot it down, Doctor.
THE DOCTOR: It saved my life. It saved Lilly and me from The Carrion in the hatching yard. Poor little thing. I'm sorry, Butterfly. It wasn't much of a life, was it?
ELIZABETH KLEIN: You were right, by the way. Rose was more susceptible to reason once the wind blew away the signal residue.
THE DOCTOR: You talked her out of it?
ELIZABETH KLEIN: Her wings were already failing her, but we landed safely in the forest.
STEFFEN: (communicator) Steffen to Klein. Are you receiving, over.
ELIZABETH KLEIN: Wait.
STEFFEN: (communicator) Steffen to Klein...
ELIZABETH KLEIN: Doctor, we haven't got much time. The Winterlack are humans.
THE DOCTOR: Yes, Klein. I found the canister in the nest. But listen. I...
ELIZABETH KLEIN: They say they're colonists, an advance party clearing this world for habitation.
THE DOCTOR: I don't care what they are. Klein, we have to get everyone off this planet.
ELIZABETH KLEIN: Doctor, they seem to think I'm working for some kind of protective organisation called the Geo-Police.
THE DOCTOR: Whatever. But we...
ELIZABETH KLEIN: When were you going to tell me about the Geo-Police?
THE DOCTOR: Oh, it never came up.
ELIZABETH KLEIN: Funny that, because whoever they are, they're Fascists, aren't they?
THE DOCTOR: Well, the Geo-Police among the worlds above the galactic plain are very picky about which civilisations they will deal with, and they are very protective of resources, and if they ring-fence a world for whatever reason they expect other races to leave it alone.
ELIZABETH KLEIN: They are Fascists. Your big bright future has got fascists in it.
THE DOCTOR: Oh Klein, if you want Fascists I'll get you a date with a Dalek.
ELIZABETH KLEIN: I quite like pretending to be from the Geo-Police. It gets me a lot of respect around here.
THE DOCTOR: I'll make you a special hat.
ELIZABETH KLEIN: But the moment they find out I'm not from the Geo-Police they will shoot me, and my accomplice.
THE DOCTOR: What accompli...? Oh, you didn't.
ELIZABETH KLEIN: They think we're working together. They think we're the Geo-Police. I'm pretty sure it's all that stops them from shooting you where I stand.
THE DOCTOR: All right, so you want me to play along, do you?
ELIZABETH KLEIN: This is no joke, Doctor. Their leader is called Steffen, he's sure to be here any moment.
THE DOCTOR: You want me to pretend to be a...?
(Approaching person.)
THE DOCTOR: Ah! Agent Klein. I wonder when I would find you. How is the Geo-Police operation going?
ELIZABETH KLEIN: Everything's fine, Doctor. Some misunderstandings with the local population but I think we can sort it out.
THE DOCTOR: Good. Ah. You must be Steffen.
STEFFEN: And you must be the Doctor.
THE DOCTOR: I see my reputation precedes me.
STEFFEN: I've been explaining to your underling...
ELIZABETH KLEIN: Underling?
STEFFEN: We are mere colonists.

(Cracking of egg shell, buzzing.)
VRILL: I am alive. I am ready. I am ready. I am reporting for duty. Where is the Authority? Where are the others? Am I alone?

STEFFEN: So what will it be, Doctor? Where are your fellow officers of justice or are you alone?
THE DOCTOR: Steffen, your operation here has been a grey area. I can see that. But I'm sure we can come to some arrangement.
STEFFEN: Are you asking me to bribe you? Doctor, you are much more fun to deal with than Klein.
THE DOCTOR: Listen to me, Steffen. You have to get off this planet. You have to leave immediately.
STEFFEN: That's not going to happen.
THE DOCTOR: It must happen.
STEFFEN: These things take time. I've lost most of my men. The Geo-Phys units and weaponry doesn't come cheap. We can't leave until our mission is a success.
THE DOCTOR: It's not a matter of success, Steffen. It's a matter of saving lives.
STEFFEN: Whose?
THE DOCTOR: Yours.
STEFFEN: I can look after myself.
THE DOCTOR: Listen to me. This is not about bribery, this is not about your mission. This is about getting all humans off this planet before we all die.

(Buzzing.)
VRILL: I am alive. I am ready. I am ready. I am reporting for duty. Where is the Authority? I am reporting for duty. Where is the authority?
(More buzzing, sounds of multiple VRILL Warriors.)
VRILL: I am alive ... I am ready ... I am reporting for duty ... I am ready...

STEFFEN: Doctor, I will not give in to scare-mongering. You'll get a sufficient bribe, don't worry.
THE DOCTOR: Unless your pitiful little band thinks it can take on an army of Vrill Warriors, you need to get out of here.
ELIZABETH KLEIN: Doctor, I don't understand. There are no more Vrill. You said yourself, there will be no more new eggs.
THE DOCTOR: The egg-laying female in a Vrill nest...
ELIZABETH KLEIN: The Queen?
THE DOCTOR: Yes, the Authority they call her - she can arrange for the development of any Vrill she likes.
ELIZABETH KLEIN: I see you've been busy while I've been away.
THE DOCTOR: I've learned what I can about the Vrill society, which is not easy when fleeing a berserk monster.
STEFFEN: What's your point?
THE DOCTOR: The Vrill Authority lays eggs. She can order them to receive particular nutrients. Some are fertilised, others are not.
ELIZABETH KLEIN: Like bees on Earth?
THE DOCTOR: Not unlike bees on Earth, yes. If a Vrill Authority thinks that she is dying, she can even authorise the right nutrients in the right egg to create a new Authority, given time.
ELIZABETH KLEIN: Ah, I see. The operative word being time.
THE DOCTOR: Yes. The Vrill society works perfectly. You saw how big the nest is. They didn't build that in a day.
ELIZABETH KLEIN: And the Authority was completely safe at the centre of the nest.
THE DOCTOR: With the Warriors on the outside protecting everyone. See? Absolutely marvellous, absolutely foolproof.
STEFFEN: What's the problem, then?
THE DOCTOR: You're the problem. You are. You drilled straight into the heart of their nest and rolled in nerve gas.
STEFFEN: It worked, didn't it?
THE DOCTOR: Genocide. You killed the Authority before she knew what hit her. It takes days to make a new Queen. You killed every adult Vrill in the nest. You murdered them all in one awful half-hour, and now the only eggs that will hatch are the ones that had already been laid.
ELIZABETH KLEIN: If the Authority is dead, surely there will only be a few more eggs hatching. A few more workers, posthumous children and then nothing.
THE DOCTOR: No. That's what you'd expect if they were bees. They're not - they're Vrill. Big difference.
STEFFEN: Well, make up your mind.
THE DOCTOR: Vrill workers are female. They hatch from fertilised eggs. There are four thousand eggs left in the hatching yard, and they are all unfertilised.
ELIZABETH KLEIN: Which means they won't hatch at all.
THE DOCTOR: No, it means they hatch as Warriors.
STEFFEN: Wait. They do what?
THE DOCTOR: The Authority is female, the workers are female, drones which I've never seen are male, the Warriors are neuter.
ELIZABETH KLEIN: And they're the default setting when the Authority is dead?
STEFFEN: This could be tricky.
THE DOCTOR: Vrill Warriors, Steffen, thousands and thousands of them, all hatching at once, right about now.

(Vrill Warriors in the nest speaking at once)
VRILL: I am ready ... I am ready ... I am reporting for duty ... Where is the Authority? ... I am alive ... I am ready ... I am ready ... I am reporting for duty ... Where is the Authority? ... Kill the Winterlack ... kill the Winterlack ... kill the Winterlack ... kill the Winterlack ... kill the Winterlack...
(Multiple Vrill speaking at once in a cacophony of buzzing and Vrill voices.)

(Closing Doctor Who theme music composed by Keff McCulloch.)

PART FOUR

(Opening Doctor Who theme music composed by Keff McCulloch.)
ANNOUNCER: Doctor Who. Survival Of The Fittest, by Jonathan Clements. Starring Sylvester McCoy and Tracey Childs. Part Four.

THE DOCTOR: The Authority is female, the workers are female, drones which I've never seen are male, the Warriors are neuter.
ELIZABETH KLEIN: And they're the default setting when The Authority is dead?
STEFFEN: This could be tricky.
THE DOCTOR: Vrill Warriors, Steffen, thousands and thousands of them, all hatching at once, right about now.

(Multiple Vrill speaking at once, chanting "Kill the Winterlack" in a cacophony of buzzing and Vrill voices.)

STEFFEN: Doctor, I've put everything I had into this operation. I can't leave without it.
ELIZABETH KLEIN: You've killed an entire race. Isn't that enough?
STEFFEN: I have Jackson to think of, and the dependants of the dead.
THE DOCTOR: Very well, Steffen. I understand your position.
STEFFEN:/ELIZABETH KLEIN: You do?
THE DOCTOR: Yes. I understood it the moment you said you couldn't leave without it.
ELIZABETH KLEIN: Without what?
THE DOCTOR: Good question, Klein. Without what?
STEFFEN: We're colonists. We're the advance party of colonists.
THE DOCTOR: Of course you are, Steffen, and that's what we'll say on the paperwork. But you're not really, are you?
ELIZABETH KLEIN: Doctor.
STEFFEN: I don't know what you mean.
THE DOCTOR: Klein here is new to the Universe at large. She's unlikely to have thought through the implications of some of your claims.
ELIZABETH KLEIN: You are infuriating when you're like this.
THE DOCTOR: Two men and a ship full of military hardware aren't colonists. And even if they were, no colonial organisation would pick a world infested with giant alien insects.
STEFFEN: Where are you going with this, Doctor?
THE DOCTOR: Where are you going, Steffen? A drill straight into the hatching-yard, nerve gassing an alien race. And all for what? Is it the eggs? Is it the building material of the nest?
ELIZABETH KLEIN: Doctor, are you suggesting that these people are just ... miners? Egg thieves?
STEFFEN: We are more like farmers.
ELIZABETH KLEIN: Not if you have to commit genocide to bring in your crops.
THE DOCTOR: Call it what you like. Butchers kill livestock, don't they? Bee-keepers steal honey. You're harvesting something, aren't you, Steffen?
ELIZABETH KLEIN: And killing another species.
STEFFEN: Farming another species.
ELIZABETH KLEIN: Well, I don't like how this smells.
THE DOCTOR: Smells. (Laugh.) Yes, Klein. You've got it.
ELIZABETH KLEIN: (simultaneously=1) I have?
STEFFEN: (simultaneously=2) She has?
THE DOCTOR: You don't want the Vrill at all. You just want their nutrients.
STEFFEN: Very good, Doctor.
ELIZABETH KLEIN: What are you talking about?
THE DOCTOR: Vrill nourish their eggs with super-concentrated nutrients. They grow to a huge size in a matter of days. It's a super-food.
STEFFEN: It can be diluted to feed humans.
THE DOCTOR: Steffen, please pay me the courtesy of not lying any more.
ELIZABETH KLEIN: But he's right, Doctor. Vrill nutrients could be food for millions.
THE DOCTOR: And if undiluted, a wonder drug? A hyper-growth hormone? Priceless, I'm sure. You're not colonists at all. You're a smash and grab operation. Some military surplus hardware and a few desperate men, and Bob's your uncle.
STEFFEN: You're no fool, are you, Doctor?
THE DOCTOR: So, what do you say? Are you ready to deal?
STEFFEN: Doctor, we'll pay the Geo-Police fines, if that's what it takes. You know we'll still make a handsome profit. But we need the nutrients. Just a few flasks of it will pay all our bills and your fines and make our fortunes.
ELIZABETH KLEIN: Is it that simple? An act of genocide written off with a penalty fee?
THE DOCTOR: Very well. This is what I propose.
ELIZABETH KLEIN: Doctor, what are you doing?
THE DOCTOR: Prepare your ship for lift-off.
STEFFEN: I'm not leaving without the nutrient gel.
THE DOCTOR: I understand. You and I will go back into the nest and get some from the hatching-yard.
ELIZABETH KLEIN: Doctor, you said yourself, the place will be crawling with Warrior Vrill.
THE DOCTOR: Well, not really. They're not going to be deaf-blind confused creatures like The Carrion. They won't wander aimlessly.
ELIZABETH KLEIN: They're going to find their way out?
THE DOCTOR: As soon as they get their bearings and sniff the dead Authority's distress signal, they are going to come streaming out of the nest, ready to kill the Winterlack.
STEFFEN: What's a Winterlack?
ELIZABETH KLEIN: That would be you.
THE DOCTOR: So, the hatching yard might be the safest place on this planet, if we can get behind the enemy lines, so to speak.
STEFFEN: You would risk your life for me?
THE DOCTOR: I think my life is already at risk, Steffen. I'm just trying to minimise the danger.
STEFFEN: And you'll drop all pending charges from the Geo-Police?
THE DOCTOR: I will see what I can do.
ELIZABETH KLEIN: Doctor...
THE DOCTOR: Shut up, Klein.
STEFFEN: Yes Klein, shut up.
THE DOCTOR: There's no time to lose, Steffen. Go back to your ship. I'll make ready.

JACKSON: (singing) And if one green bottle should accidentally fall, there'll be four hundred and twenty-seven green bottles, sitting on the...
(Bleeps of communicator.)
STEFFEN: (communicator) Jackson, we're leaving.
JACKSON: But the harvest.
STEFFEN: (communicator) The Doctor knows his way around the Vrill nest. He's got a plan.
JACKSON: He's gonna help you take the nutrients?
STEFFEN: (communicator) What can I say? We've found one who'll take a backhander. He's found a compromise that's going to get us out of here safely.
JACKSON: Roger that.
STEFFEN: (communicator) Heat up the engines. We're going to need a quick lift-off.
JACKSON: Why so quick?
STEFFEN: (communicator) Because any moment now we're going to be facing an army of Vrill.

ELIZABETH KLEIN: What was that about?
THE DOCTOR: What was what about?
ELIZABETH KLEIN: You're handing him what he wants on a plate. I told you to bluff a little, not collaborate.
THE DOCTOR: I don't need a lecture on moral high ground from you of all people.
ELIZABETH KLEIN: You're taking a bribe, you're helping him steal from the Vrill.
THE DOCTOR: If it'll get him off-world, why not?
ELIZABETH KLEIN: What about the Vrill?
THE DOCTOR: They will be turning up very soon to kill everyone.
ELIZABETH KLEIN: I thought you made that bit up.
THE DOCTOR: No. They really will.
ELIZABETH KLEIN: And so you want to go back into the middle of the nest? You said it's crawling with Vrill, and they are not happy.
THE DOCTOR: It's crawling with Warrior Vrill. They're too big to fit down the drill tunnel. We'll only be in danger at...
ELIZABETH KLEIN: At either end.
THE DOCTOR: Come with me or stay here, Klein. It's up to you.
ELIZABETH KLEIN: You're up to something.
THE DOCTOR: The very thought of it.
ELIZABETH KLEIN: What aren't you telling me?
THE DOCTOR: I need to get back into the hatching yard.
ELIZABETH KLEIN: Why?
THE DOCTOR: To help ... the Vrill.
ELIZABETH KLEIN: There's more to it than that. You're hiding something.
THE DOCTOR: I can't abandon the Vrill.
ELIZABETH KLEIN: They're doomed. No more eggs.
THE DOCTOR: Well, the workers think they're doomed, the warriors are just going to try and kill us all, but I ... I just need to have another look around the hatching yards.
ELIZABETH KLEIN: And then what? You'll be behind enemy lines. The Warrior Vrill will be heading this way, they'll be attacking the ship...
THE DOCTOR: I imagine that they will, yes.
ELIZABETH KLEIN: The TARDIS. You're going to get back in the TARDIS and run away, aren't you? Aren't you?
THE DOCTOR: If the situation really isn't possible to resolve then yes, Klein. We will have no choice but to walk away.
ELIZABETH KLEIN: So, perhaps you could be a little clearer when telling me it is in my interest to go with you.
THE DOCTOR: All right. I'm not saying I approve, Klein, but what choice do we have?
ELIZABETH KLEIN: We could go back to the TARDIS right now. Abandon Steffen, abandon him to a death by poetic justice, torn apart by a hundred Vrill.
THE DOCTOR: I'm not ready to give up yet, not even on Steffen.
ELIZABETH KLEIN: What are you going to do?
THE DOCTOR: I have everyone's best interests at heart, Klein. Bear with me.
ELIZABETH KLEIN: Everyone's? Every human's.
THE DOCTOR: Theirs and yours and mine. I have a very delicate but very well-meaning plan.
ELIZABETH KLEIN: And the Vrill? What about the Vrill? The common good comes before the private good.
THE DOCTOR: The Vrill too. Trust me, Klein. I'm a Doctor.

(JACKSON singing while tapping controls.)
JACKSON: I'm a pre-flight checker, I'm a pre-flight check. I'm engines go, and airlocks closed, and all looks green on tech.
STEFFEN: (communicator) Jackson, do you read?
JACKSON: Loud and clear.
STEFFEN: (communicator) We're up the Vrill tunnel.
JACKSON: Roger that.
STEFFEN: (communicator) You've got to head straight up, out of the atmosphere, otherwise the flying Vrill will get you.
JACKSON: Aye-aye.
STEFFEN: (communicator) Once we've got what we need, I'll radio you when we're ready for collection. Then you're going to have to drop down as fast as you can, be ready to head back out again.
JACKSON: Yeah, I've got it.
STEFFEN: (communicator) Seriously. You're going to need to drop out of orbit like a stone and pull five G's heading back up, got that?
JACKSON: Got it. Base out. Honestly, do I look stupid?

(Moving through bushes.)
ELIZABETH KLEIN: Here it is, Doctor. Rose dragged me the whole length of the tunnel before dumping me in the forest.
THE DOCTOR: We've got to get in there before the first wave of warriors comes out of the main entrance...
(Buzzing starts.)
STEFFEN: All right, all right, let's do it.
THE DOCTOR: Oh! Here they come!
STEFFEN: Steffen to Jackson, this is not a test. Take off. Take off now, they're coming!
THE DOCTOR: Inside! In the tunnel!
JACKSON: (communicator) Steffen, the mass reading's off the scale. There's hundreds of them. Thousands!

STEFFEN: (communicator) Get out of there, Jackson.
JACKSON: Okay. Here we go.
STEFFEN: (communicator) Put the guns on automatic, give yourself a covering blanket of fire. Might slow them down.
JACKSON: Will do.
(Guns firing.)
JACKSON: Launching now. Here we go!
(Rocket taking off as guns fire.)

STEFFEN: That's it. He's taking off.
THE DOCTOR: Good, good. As long as he gets ahead of the Warriors, we're laughing.
ELIZABETH KLEIN: Okay. I'm just hoping we don't run into a worker coming up the passage.
THE DOCTOR: Just in case we do perhaps it's best if I go first.
(Walking forwards.)
ELIZABETH KLEIN: You couldn't work that out before we got in the tunnel...
THE DOCTOR: Oh, just let me pass. Budge over.
ELIZABETH KLEIN: This had better work.
(Movement. THE DOCTOR groans with effort.)
THE DOCTOR: Ah! Through. How's that for lebensraum?
STEFFEN: Are you two entirely sure that you know what you're doing?
THE DOCTOR: (simultaneously=1) Yes.
ELIZABETH KLEIN: (simultaneously=2) No.
STEFFEN: That's what I was afraid of.

STEFFEN: (communicator) Steffen to Jackson. We're proceeding into the nest. How are you doing? Are you in orbit yet?
JACKSON: Not yet. Bugs are in pursuit. I'm letting them chase me for a few miles.
STEFFEN: (communicator) What? Why?

JACKSON: (communicator) Because once they lose sight of the ship, they're probably going to turn round and head back to you.
STEFFEN: Good thinking. Lead them as far away as possible first. Smart.
(Walking over, walking stops.)
THE DOCTOR: Here we are. Hatching yard.
ELIZABETH KLEIN: I don't see any Vrill.
STEFFEN: All the Warriors are off chasing my ship. Doctor, you're a genius.
THE DOCTOR: Well, I try.
STEFFEN: Wait! Everybody down!
THE DOCTOR: No! Put down the gun. Point it at the...
(Blast.)
STEFFEN: Are you crazy? Let go of the rifle. There's a Vrill.
THE DOCTOR: Indeed there is.
LILLY: Welcome, Doctor.
THE DOCTOR: Hello, Lilly. It's good to see you again.
LILLY: Doctor, I am pleased that you are not dead.
THE DOCTOR: Aren't we all, Lilly.
LILLY: The Warriors have hatched, by eight times eight times eight...
THE DOCTOR: Yes, yes, that is a lot. Lilly, I would like to introduce Steffen and Klein, whom you already know.
LILLY: Is she...?
THE DOCTOR: She's not that thing that you probably shouldn't say out loud, no. She's a friend.
LILLY: Welcome, Klein. Welcome, Steffen.
STEFFEN: This is unreal. I can't believe this is happening, it's ... talking. It's really talking.
THE DOCTOR: Yes, she is.
STEFFEN: Quickly Doctor, we need to find...
THE DOCTOR: Steffen, be very careful what you say. Lilly?
LILLY: Yes, Doctor?
THE DOCTOR: Would you be kind enough to show Klein the place where we defeated the Carrion?
ELIZABETH KLEIN: What? Why on earth would I want...?
THE DOCTOR: She'd love to see it, wouldn't you, Klein?
LILLY: Of course, Doctor.
ELIZABETH KLEIN: But Doctor...
THE DOCTOR: Klein, you go with Lilly and look at the far side of the hatching yard, far away from Steffen and myself?
ELIZABETH KLEIN: Ah! Oh, right. With Lilly, you mean?
THE DOCTOR: Yes. With Lilly.
LILLY: Come, Klein. Let me show you.
ELIZABETH KLEIN: That would be great.
(Rubbing.)
STEFFEN: Doctor, what are you doing?
THE DOCTOR: Lilly is our friend for as long as we act like hers.
STEFFEN: Oh. Right.
THE DOCTOR: So I think it's best, considering you know why we're here that she's far away from you-know-what until you-know-when.
STEFFEN: Why are you being so coy? Can't you just say...?
THE DOCTOR: Shh! The Vrill believe everything they hear. And I don't want them hearing something that ... upsets them.

(Bubbling.)
ELIZABETH KLEIN: So this is where The Carrion died.
THE CARRION: (faint) Distress...
LILLY: I can still hear its last signals in the air.
THE CARRION: Distress, intruder...
LILLY: I am afraid.
ELIZABETH KLEIN: No, Lilly. It's definitely dead. So, show me where you and the Doctor helped the Warrior Vrill to hatch.
LILLY: It was not I. It was the Doctor. We should not help the Warrior Vrill hatch. They must hatch themselves.
ELIZABETH KLEIN: All right. All right, Lilly. Show me where the Doctor did it.
LILLY: We hid among the eggs, but The Carrion saw us.
ELIZABETH KLEIN: Where did you retreat?
LILLY: Here. This is where it hatched.
(Walking over.)
LILLY: The warrior that the Doctor called Butterfly.
ELIZABETH KLEIN: Oh, the egg shards are very tough. Not really brittle ... I can't break one in half. How exactly did you help the Warrior Vrill hatch?
LILLY: The Doctor had a piece of unknown substance, a thing that was like a shard of sharpened material. I thought it was of Winterlack manufacture, but he said it was a "Just the key to my TARDIS." Then he lost the "Just the key to my TARDIS."
ELIZABETH KLEIN: He lost the key?
LILLY: Yes.
ELIZABETH KLEIN: Of course.
LILLY: Of course what?
ELIZABETH KLEIN: That's what the Doctor wouldn't tell me. He wanted to come back to look for the key. Oh, Lilly. Listen very carefully. I want you to trace your own scent markers. I want you to show me exactly where you and the Doctor were when you were running from The Carrion.
LILLY: We were here.
ELIZABETH KLEIN: No, Lilly. I mean exactly . Step by step.

(Walking, then stopping.)
THE DOCTOR: This is the place. This is the centre of the nest.
STEFFEN: Are you sure?
THE DOCTOR: That dead body over there? That's The Authority.
STEFFEN: Oh. Okay.
(Walking off.)
STEFFEN: In which case the gel pods should be somewhere nearby.
THE DOCTOR: Don't touch them.
STEFFEN: What are you afraid of, Doctor? It's just a sort of alien honey, I suppose.
(Tasting.)
STEFFEN: Here. Why don't you try some? The Vrill don't need it.
THE DOCTOR: I'd rather not, thank you. So these pods here, they contain the gel that turns neuter eggs into new workers?
STEFFEN: Yeah, but we don't want those. We want something much rarer.
(Walking.)
STEFFEN: Ah. This is what I came for.
THE DOCTOR: What's that?
STEFFEN: These, Doctor, are the most valuable things you can imagine.
THE DOCTOR: I have a very vivid imagination.
STEFFEN: They are very special Vrill nutrients.
THE DOCTOR: But they're not the usual colour.
STEFFEN: No, they're not. This is very rare.
THE DOCTOR: How rare?
STEFFEN: Just a few handfuls are probably all there is in the nest.
THE DOCTOR: What's it for?
STEFFEN: For? It's for me.
THE DOCTOR: What does it do?
STEFFEN: Do? Doctor, just a drop of this is a wonder drug.
THE DOCTOR: I know that, I mean, what does it do for the Vrill?
STEFFEN: Oh, they don't need it any more - you said it yourself, they're already dead, they just don't know it yet.
THE DOCTOR: But what would it do?
STEFFEN: It would make a new Supreme Vrill, like this dead one here.
THE DOCTOR: It would create a new Authority?
STEFFEN: A new consort, too.
THE DOCTOR: An Adam and Eve for the Vrill. Why not let them?
STEFFEN: What's the point?
THE DOCTOR: I don't care how many full flasks you take out, but leave one authority gel and one consul gel here with me.
STEFFEN: Or what?
THE DOCTOR: Try me.
STEFFEN: You're a puny little man, and I'm the man with the gun.
THE DOCTOR: Just how fast can you shoot before I can shout out to Lilly what you really are, and then you're a dead man just the same. Shall I give it a whirl?
STEFFEN: Doctor, these are ... these are worth so much money.
THE DOCTOR: To the Vrill they're worth everything, so take as much as you can carry, but leave one of each gel behind here for me.
STEFFEN: This is stupid! We are part of the natural order of things. Survival of the fittest. It applies everywhere in nature apart from to the human race. We're supposed to just tiptoe around other cultures out of some insane sense of fair play.
THE DOCTOR: Makes perfect sense to me. You've got more than enough to pay your debts, so back away now, and head for the exit.
STEFFEN: You drive a hard bargain, Doctor.
THE DOCTOR: Tough.

(Vrill movement.)
LILLY: And this is where the Doctor opened Butterfly's egg.
(Rummaging.)
ELIZABETH KLEIN: Come on. About time my luck changed. Aha! Oh Lilly, you are a good Vrill.
LILLY: Am I?
ELIZABETH KLEIN: I found the key.
LILLY: The Doctor will be pleased.
ELIZABETH KLEIN: Yes. Erm ... I'll tell him myself, if that's all right with you. When the time is ... right.
LILLY: I should not tell the Doctor that you have found it?
ELIZABETH KLEIN: No Lilly, I will tell him.
(Walking over.)
STEFFEN: Time to leave.
ELIZABETH KLEIN: You've got everything you need?
STEFFEN: So the Doctor says.
THE DOCTOR: (off) Lilly? Can you buzz over here a moment?
LILLY: The Doctor calls me?
ELIZABETH KLEIN: Yes, Lilly, go to him.
LILLY: As he commands.
(Buzzing of flying over.)
STEFFEN: So, back to the drill tunnel.
ELIZABETH KLEIN: No. We should head out through the main tunnels, through the atrium.
STEFFEN: But the drill tunnel is the quickest route.
ELIZABETH KLEIN: And it's jam-packed with our recent scent marks.
STEFFEN: You mean, the Warriors?
ELIZABETH KLEIN: The Warriors will smell our signals on the exit. They'll be waiting for us when we leave.
STEFFEN: You know them that well?
ELIZABETH KLEIN: It's what I'd do. Come on, we've got a better chance going out through the atrium. (Calling, echoed) Hurry up, Doctor, we don't have much time!

(Buzzing.)
LILLY: You wanted to see me, Doctor?
THE DOCTOR: Tell me, Lilly. How are the new Vrill made?
LILLY: Authority gel on one egg, consort gel on one egg, and a mating pair is created.
THE DOCTOR: How much of this gel do you need?
LILLY: Only a small amount. A handful.
(Jar opened.)
THE DOCTOR: This much?
LILLY: That will be sufficient.
THE DOCTOR: Are there any unhatched eggs left? Any at all?
LILLY: Just a few. Less than eight.
THE DOCTOR: We only need two.
LILLY: There are two.
THE DOCTOR: That's all we need. We've got the gel, we've got the eggs. We can made an Adam and Eve for a new generation of Vrill. We can save the nest.
LILLY: We cannot.
THE DOCTOR: What? Oh, don't tell me there's small print?
LILLY: The Authority must order the use of the gel. Only an Authority can order the making of a new Authority. Only an Authority can provide the gel.
THE DOCTOR: Okay Lilly, er ... Lilly, I want you to think about this, all right?
LILLY: Think about what?
THE DOCTOR: Who is the only one who can provide the gel?
LILLY: The Authority.
THE DOCTOR: And who's got the gel right now?
LILLY: You have, Doctor.
THE DOCTOR: Right. So what does that make me?
LILLY: Doctor? Are you an Authority?
THE DOCTOR: I most certainly am. Right Lilly, you've got your mission. Take these flasks, one for Adam, one for Eve. Put them on the two best-looking unhatched eggs you can find, get them in the bubbling waters in the right place, all right? Because you know what that means?
LILLY: It will create a new Authority.
THE DOCTOR: Yes, Lilly, that's exactly what it will do.
LILLY: Do you wish it so?
THE DOCTOR: Yes, I wish it so. Now, go.
(Buzzing.)
THE DOCTOR: Go. Do it. (Laughs.) A new beginning. (Laughs.)

(Echoed walking.)
ELIZABETH KLEIN: Now what's keeping the old fool?
STEFFEN: Beats me. How far to the atrium?
ELIZABETH KLEIN: We're nearly there. If I remember right... Ah. Here we are.
STEFFEN: (sigh of relief) I've never been so pleased to see daylight.
ELIZABETH KLEIN: Me neither. Well Steffen, this is where we part company.
STEFFEN: You're not coming with me on the ship?
ELIZABETH KLEIN: Er, no. I have my own transport. Call Jackson down and get out of here before the Warrior Vrill come back.
STEFFEN: But what about the Doctor?
ELIZABETH KLEIN: He'd better hurry. No time. Come on. Call it in. Get your ship down here.

STEFFEN: (communicator) Steffen to Jackson. Don't wimp out on me now.
JACKSON: Jackson receiving. Over.
STEFFEN: (communicator) We're at the main entrance to the nest. Get down here fast.
JACKSON: Coming in hot.
STEFFEN: (communicator) The hotter the better. Whatever holds off any Vrill.
JACKSON: Roger that. ETA, one minute.
(Rocket motors.)

(Walking quickly.)
THE DOCTOR: Hello, you two. Did I miss anything?
STEFFEN: They're on their way.
ELIZABETH KLEIN: Better make it fast.
(Distant buzzing.)
THE DOCTOR: Not quite fast enough, I fear. I hear buzzing.
ELIZABETH KLEIN: It's the Warriors. They're already back. To the TARDIS, quick.
THE DOCTOR: I'm afraid the TARDIS isn't much help to us now.
VRILL: Unidentified intruders ... identify yourselves ... identify yourselves ... identify or die ... identify ... identify yourselves ... identify or die...
STEFFEN: I can shoot the first couple, but after that we're dead.
THE DOCTOR: No Steffen, don't shoot anything.
ELIZABETH KLEIN: Doctor, they'll listen to you. Hold them back.
THE DOCTOR: All right, all right. All Vrill listen to me. I am the Doctor. I am The Authority. Do not attack anyone. Stay where you are. Do not interfere.
(Buzzing.)

JACKSON: Jackson to Steffen. We're nearly there. Get ready to run for the ship. You can't miss us - the hull's going to be glowing red-hot.
STEFFEN: (communicator) Stand by.
(Rocket motors descent sound.)

STEFFEN: My cue to leave, I think.
ELIZABETH KLEIN: You got that right.
THE DOCTOR: Klein, Klein, the exit is that way.
ELIZABETH KLEIN: I'm not going that way, Doctor, I have somewhere else to be.
(Walking off.)
THE DOCTOR: Klein, where on Earth ... No. No, you can't.
ELIZABETH KLEIN: Oh, but I can. The TARDIS is right here in the atrium.
THE DOCTOR: Klein, we can't leave the planet, not yet.
(Buzzing.)
ELIZABETH KLEIN: Let me through, there's a good Vrill, let me through. Thank you.
VRILL: You are not an intruder. You are a friend.
THE DOCTOR: Klein, you are playing with fire.
ELIZABETH KLEIN: I am the Doctor, you know. I am The Authority, so you should just back away and let me through.
THE DOCTOR: Klein!
ELIZABETH KLEIN: If I've got the right idea, it would seem that the truth is whatever the Vrill hear, and they are happy, for as long as they hear only things they like the sound of. So, I am the Doctor. I am The Authority, and let me through.
THE DOCTOR: Klein, we can't leave yet.
ELIZABETH KLEIN: Because you haven't found your precious key?
THE DOCTOR: How do you know about my...?
(Metal jingling.)
THE DOCTOR: The key to the TARDIS. Hand it over, Klein.

ELIZABETH KLEIN: The shoe's on the other foot now, Doctor. Now I am in the driving-seat.
THE DOCTOR: Haven't you learned anything on our travels together, Klein?
ELIZABETH KLEIN: Attention all Vrill. Do not let that creature approach the blue box. If he tries you must kill him.
(Agitated buzzing.)
THE DOCTOR: What are you doing?
ELIZABETH KLEIN: Don't contradict me. You know how the Vrill don't like it.
THE DOCTOR: No, no ... you don't understand.
ELIZABETH KLEIN: Oh yes I do. You manipulated me. Tricked me into obliterating my own history. My own future. Did you really believe that I could just forget about that?
THE DOCTOR: I thought we were making progress.
ELIZABETH KLEIN: Because that's what you wanted to believe. That I could somehow be rehabilitated to see the Universe through your blinkered eyes. You condescending hypocrite! Well, now it's my turn. Every journey we've made, I've been watching and learning as you operated the TARDIS. Now it's mine again. All Time and Space will lay before me, a thousand-year Reich.

THE DOCTOR: Once a Nazi, always a Nazi, Klein. You'll ruin everything.
ELIZABETH KLEIN: The Reich will rise again. It will be my victory.
THE DOCTOR: Not on Earth. Here! You'll ruin everything here!
ELIZABETH KLEIN: What do you mean?
THE DOCTOR: The moment the TARDIS leaves this continuum, the gift will be revoked.
ELIZABETH KLEIN: The what?
THE DOCTOR: The translation. There will be no more translation. Vrill and humans will be unable to communicate. Steffen or some fool like him will just repeat the cycle. All hope of a treaty will be lost. It will just be the Vrill and humans in a struggle to the death.
ELIZABETH KLEIN: In which case, Doctor ... you'd better start running.
(Door opened.)
THE DOCTOR: No!
(Door closed. TARDIS dematerialisation.)

JACKSON: Jackson to Steffen. ETA, thirty seconds. Get ready to run.
(Rocket motors.)

(Multiple buzzing.)
STEFFEN: The blue box. It just ... disappeared.
THE DOCTOR: Time to run, Steffen.
STEFFEN: You had transmat technology and you never told me?
(Walking.)
STEFFEN: Hey, it's awfully quiet all of a sudden.
THE DOCTOR: Really, Steffen, start walking down the hillside, quick as you like.
(Buzzing in background.)
STEFFEN: Why are the Vrill approaching again? I thought you ordered them to stop.
THE DOCTOR: They can't hear me any more, Steffen.
STEFFEN: And we can't hear them?
THE DOCTOR: That's right. Keep walking, keep walking.
STEFFEN: What's happened?
THE DOCTOR: We've lost the gift of the TARDIS.
STEFFEN: The what?
THE DOCTOR: There's no more communication between us, Steffen. Us and the Vrill. We're deaf to each other.
STEFFEN: So what's the problem? Doctor, why the sudden retreat?
THE DOCTOR: Because the very last thing that the Vrill heard was someone claiming to be the Doctor leaving them.
STEFFEN: But it was Klein.
THE DOCTOR: The Vrill aren't too hot on truth and lies, Steffen. They are quite gullible like that.
STEFFEN: Okay Doctor, whatever.
THE DOCTOR: If you value your life, keep walking down the hillside.
STEFFEN: I'm not playing your game. I'm going to play Klein's.
THE DOCTOR: Not advisable. Your ship is approaching. We're nearly out of trouble. Steffen! Come back! It's too dangerous. They won't hear you!
STEFFEN: Hello, Vrill!
(Buzzing.)
STEFFEN: Remember me? I am the Doctor. I am the Doctor. I just need to go back to the hatching yard.
THE DOCTOR: (distant) Steffen, the ship is here!
STEFFEN: Let me through, there's a good Vrill.
(Movement.)
STEFFEN: Hey, no shoving. Hey...
(Angry buzzing. Attacking. STEFFEN screams.)

(Ship door opened.)
JACKSON: Doctor, where are the others? Steffen!
(Running up.)
THE DOCTOR: Too late. He's gone. They've both gone.
(Buzzing continues.)
JACKSON: The Vrill are coming. They're heading this way.
THE DOCTOR: Get us up, straight up into orbit. Out of the atmosphere.
JACKSON: Roger that.
(Rocket motors. Buzzing.)

(Inside rocket.)
JACKSON: Orbit achieved.
THE DOCTOR: We're out of the atmosphere?
JACKSON: Yeah, like I said, we're in orbit.
THE DOCTOR: Thanks, Jackson. You saved my life.
JACKSON: Oh, just returning the favour, Doctor. If you hadn't warned us about the Vrill they'd have torn us apart on the ground.
THE DOCTOR: Well, I guess we're even.
JACKSON: I guess we should give it a couple of weeks in orbit.
THE DOCTOR: What? Why?
JACKSON: Well, there's nothing but Warriors down there. Without workers to find them food they'll starve to death by then. Then we can go back down and clean up. Grab what we want.
THE DOCTOR: I'm not all that sorry to disappoint you, Jackson, but that's not going to happen.
JACKSON: But Steffen said...
THE DOCTOR: I don't care what Steffen said. The Vrill have a new Authority. They've made it through by the skin of their teeth. But by the time this generation of Warriors dies off, the nest will be entirely repopulated.
JACKSON: What? How did that happen?
THE DOCTOR: Well, er...
(Exhales air through his lips.)
THE DOCTOR: The Vrill are sneakier than you might think.
JACKSON: Oh. I guess so. Sorry about Klein.
THE DOCTOR: What?
JACKSON: Sorry about Klein, dying down there.
THE DOCTOR: Oh, she's not dead. She got clean away.
JACKSON: Oh, good.
THE DOCTOR: Not really. Might have been better for us all if the Vrill had got her too.
JACKSON: I thought she was your friend.
THE DOCTOR: No. We were never really friends.
JACKSON: But if she got away then, where did she go?
THE DOCTOR: Where indeed? She could be anywhere, literally anywhere, and there's nothing I can do to stop her. The Universe had better watch out.
