Doctor Who (1963) s15e08 Episode Script

(DOCTOR WHO THEME) Destroy them.
Destroy them now! No! We must find out what happened.
We must restore them to their full size and interrogate them.
(SNARLING) NUCLEUS: Help me out.
Professor Marius.
Oh, no, not you, too.
Yes, Doctor.
Contact has been made.
-Now I serve the purpose.
-What? That pathetic crustacean, your leader? You're speaking of the Nucleus, the Nucleus of the Swarm.
NUCLEUS: Take me to him.
-Finding the macro world difficult? -NUCLEUS: It suits me well.
-I thought I had got rid of you.
-NUCLEUS: You were mistaken.
I made use of your escape route, through the eye.
Yes.
You'd have known about that, wouldn't you? Another mistake and a costly one, Time Lord, because now, thanks to your dimensional stabiliser, I am no longer forced to exist in the micro world to breed and multiply.
My Swarm, when it is hatched on Titan, will no longer be invisible microbes, prey to all, but mighty and invulnerable creatures.
Invincible.
The age of man is over, Doctor.
The age of the virus has begun.
I've heard it all before! You megalomaniacs are all the same.
Bring him with us to Titan, to be consumed by the Swarm.
-How do I look? -K9: Friend, mistress.
If I can just get close enough to that Nucleus, we'll see how friendly I am.
Hostiles approaching, with the Doctor.
(WHISPERS) Come on.
Hurry.
Hurry.
It is time for the spawning.
I must get to the place prepared on Titan.
MARIUS: Nurse, take over here.
-I must assist the Nucleus.
-NUCLEUS: Hurry.
-Come with me.
-NUCLEUS: Breeding time approaches.
Nurse, not that way.
Stop them! -Take them away! -NUCLEUS: No.
They are simply trapped.
Marius, stay here to make sure the Doctor doesn't escape and make contact with all other staff in the Foundation.
Bring the Doctor to us later.
Hurry.
-Now what? -Now nothing.
Doctor, if we get to Titan first, we can still beat that thing.
No, we can't.
The dimensional stabiliser is still in the isolation ward.
Without it, the Tardis won't move an inch.
-You mean there's nothing we can do? -I didn't say that.
K9.
Now listen to me, K9.
Do you think you could poleaxe Do you think you could poleaxe Marius? -Poleaxe? -Yes.
-Knock him out.
-Affirmative.
My photon beam weapon ray has four levels of intensity, Doctor.
-Kill, paralyse -No, no, no, not kill.
Not kill.
-Just knock out.
-Affirmative.
Good dog.
All senior staff, report to reception.
This is Professor Marius speaking.
All senior staff, report to reception.
K9.
K9, I no longer require you to obey DOCTOR: You're a good dog, K9.
Good dog.
Come on, Leela, quickly.
We haven't got a moment to spare.
Not frightened of blood, are you? You, the mighty huntress.
Just hurry up.
Haven't we been through all this before? I had a virus then.
I'm immune now.
Something must have happened while you and I were inside my head.
I want to find out what.
(BEEPING) Ah! That's interesting.
You see that? That little fishhook is the only thing that you and I have in common.
It wasn't there before.
So it must be the antibody.
The immunity factor.
How did what I have get into your bloodstream? Quite simple.
Your clones absorbed into my bloodstream and passed on the immunity to me.
All we have to do is isolate it, analyse it, duplicate it, inject it into Marius and he in turn will be able to cure all the others.
What about the Nucleus? What about Titan? Come on, one thing at a time.
One thing at a time.
Faster.
Faster.
We can't.
We'll burn out the motors.
Let them burn out.
Once we reach Titan and the breeding tanks, our job is finished.
-What about the Doctor? -NUCLEUS: He will follow.
Marius will make sure of that, whatever happens.
Faster.
Use all the fuel.
Faster.
(WHIRRING GETS LOUDER) Doctor, look.
It's working.
Sometimes my brilliance astonishes even me.
Come on, Marius.
Wake up, wake up.
-Come on.
-Where's Parsons? What happened? He's dead, I'm afraid.
Do you remember anything? I remember Lowe coming in and then Parsons And then a flash and then nothing.
-Did the experiment work? -Yes and no.
Unfortunately, the Nucleus got away by means of the dimensional stabiliser.
It's on its way to Titan to breed.
-Was I taken over? -Yes, it got to you.
But we found the immunity factor.
So we're safe here for a while.
-What was it? -It was something in Leela.
Something we all missed.
This is it.
You'll have to cultivate a great deal more.
-Yes.
-If those antibodies can confer immunity, they can be used to attack the Nucleus.
Attack the Nucleus, oh, that's dangerous.
Of course, it's dangerous.
If we allow the Nucleus to breed and swarm, it'll go through the entire solar system like a plague of giant locusts.
But will you get to Titan on time? Yes, by means of the dimensional stabiliser.
Safran on Titan.
Safran on Titan.
The hive is prepared.
The breeding tanks are ready.
Temperature and humidity are set.
I await your arrival, from the generation of the Swarm.
Maximum speed.
We have reached maximum speed.
Faster.
We must go faster.
Now the time for spawning is very close.
(NUCLEUS BREATHING HEAVILY) -LEELA: How much longer? -We can't rush these things.
They're breeding as fast as they can.
K9 will tell us when they got the most powerful strain.
Doctor, why don't we just blow up Titan? Nucleus, breeding tanks, everything? It's your answer to everything, isn't it? Knock it on the head.
Effective, isn't it? Smash it once and for all.
-Well? -With what? -This is a hospital, not an arsenal.
-All right, what are you going to do? Confirm.
Confirm strain C53 1 has lethal capacity.
Doctor, we've done it.
Congratulations.
There's not a moment to be lost.
Cultivate C531 .
-Thank you, K9.
-And Now, just get it into the tanks and wait for it to attack the Nucleus in the same way it attacked us, microscopically.
-It's neat, don't you think? -Is that all? If we can get to Titan on time.
If we can get past Lowe and the others.
If it works when we get it in there.
If -I thought you didn't like killing.
-I don't.
Then why are you doing all this? The virus has a perfect right to exist as a virus.
Not as a giant storm threatening the entire solar system.
Everything has its place.
Otherwise the delicate balance of the whole cosmos is destroyed.
-I still say we should blow it up.
-MARIUS: Doctor.
The batch is complete.
Good.
Now for the Tardis.
(NUCLEUS BREATHES HEAVILY) Remember, I must be protected in the hive.
The future of the Swarm depends on you now.
-Good luck, Doctor.
-Thank you, Professor.
-Oh, Professor.
-Yes.
I don't suppose we could borrow K9, could we? -Borrow K9? -Shh.
-What for? -Well, I'm not at liberty to say, but he could be very useful.
Of course, I understand.
-K9, obey the Doctor.
-Affirmative.
(WHOOSHING) (WHOOSHING) -LEELA: Doctor, what is it? -They've started to hatch.
Let's go.
-Now what's the matter? -There's a man at the door.
(KNOCK ON DOOR) Come in.
(SCREAMING) Thank you, K9.
Well, Doctor, what's wrong? Why didn't my blaster work? They're developing a resistance to radiation.
-Their internal cell -Problem.
I have a problem.
Offensive capability seriously diminished.
Reserves very low.
K9's breaking up, my blaster's finished, what are we going to do? -Shall we try using our intelligence? -Well, if you think that's a good idea.
DOCTOR: Come on.
-(WHISPERING) K9, do you see that guard? -(WHISPERING) Affirmative.
I want you to decoy him.
(GUN FIRING) Mission accomplished.
Good job.
Your turn now, Leela.
(WHISPERING) See you back at the Tardis.
Or not.
Good luck, Doctor.
You know we should've done what I said.
-What was that? -Blow them up.
Goodbye, Doctor.
(GUN FIRING) Your futile attempt has failed.
As we knew it would.
Now, you will join the Nucleus.
-Well, I'd rather not, actually.
-You have no choice.
Oh, look.
Look, they appear to be hatching.
Are congratulations in order? You will join the Swarm, to be consumed, to become part of our purpose! (SCREAMING) Well done, K9, well done.
Come on.
Let's get out of here while there's still time.
-I cannot.
All reserves finished.
-What? Come on.
Come on, K9.
NUCLEUS: Come back, Doctor.
We need you.
-Did you kill it? -No, I lost the antibodies.
What? Never mind, Doctor.
I found the answer.
-What? -Knife them in the neck.
Can you do that to a thousand, a thousand thousand? -What are we going to do? -That's a good idea.
Take K9 back to the Tardis, he's out of juice.
NUCLEUS: Who's there? Is that you, Time Lord? Well, as far as I know, there's no one else except you and me here, so it must be me.
You're finished, Doctor.
-Not quite.
-There is no escape for you now.
You are destined to become part of the purpose.
Well, that depends on how long it's going to take you to get out of there.
NUCLEUS: Fool.
Do you think a metal barrier can contain the Swarm? (NUCLEUS SCREECHING) (WHOOSHING) Doctor! (WHOOSHING) (NUCLEUS SCREECHING) Why did you not wait? (WHOOSHING) (NUCLEUS SCREECHING) (DOCTOR LAUGHING) -It is gone? All of it? -Yes.
Yes.
Methane atmosphere, mix well with oxygen and run.
That was a good idea of mine, K9, to blow it up.
Affirmative.
What do you mean, it was a good idea of yours? It was my idea.
-What was? -To blow it up.
Well, then you should be feeling very happy.
Yes.
I am.
Shall we return K9 to the Professor? (DOCTOR CLICKING TONGUE) -Goodbye.
-Goodbye, Doctor.
And thank you for everything you've done for us.
It's been a pleasure, Professor.
It's been a pleasure.
Do you know that without K9 I think we'd have been part of the Swarm by now? We'd never have managed without him Her It.
Sorry, K9.
Apologies are not necessary.
Thank you, mistress.
I think K9 has taken to you.
Oh, actually, I have to return to Earth shortly and you could do me a great favour if Take K9 with us? -Yes.
-No.
Yes, please, Doctor, please, please, let's take him.
K9 seems to have made up his own mind.
(SNIFFING) I only hope he's Tardis trained.
(WHOOSHING)
