POLO [OC]: Success. My plan has worked. The strangers and their unusual caravan accompany me to Lop. Our route takes us across the Roof of the World, down to the Kashgar Valley and southeast to Tarkand. Here we join the Old Silk Road, along which the commerce and culture of a thousand years has travelled to and from Cathay. I wonder what the strangers' reaction will be when I tell them what I propose to do?

IAN: Oh, it's enormous!

BARBARA: Look at the joins in the blocks, Ian.

IAN: Yes, no mortar. Must have been built with tremendous accuracy.

BARBARA: Yes, the Egyptians did the same thing. So did the Indians of Central and Southern America.

IAN: A precise distribution of weight, that's the key, isn't it?

BARBARA: Yes. Marvelous, isn't it?

DOCTOR: Yes, now before you two get carried away, I think we'd better go and find Susan, hmm?

BARBARA: Yes, you're quite right.

SUSAN: It's too far for you, Grandfather.

DOCTOR: Well, if it is, I shall have to give up, and I'm not going to give up before I've tried. And remember, you must think of the other two. They must be constantly reminding themselves they're only one inch high. There's only the two of us to help them.

SUSAN: All right. But you let me go first.

DOCTOR: Yes, yes, yes, go on.

PRAPILLUS: Hilio, the Menoptra have no wisdom for war. Before the Animus came, the flower forest covered the planet in a cocoon of peace. Our ancestors carved temples like this for resting places of our dead, but that was all the work we did. There were no other plans to make. Light was our God and we existed in light, flying above thought. Our banishment has taught us of enemies and weapons, and my captivity has taught me strategy. They tore my wings from me and I felt, as you feel, that all was lost. But if our Gods favour our survival, we must learn their lesson and use our brains and not our wings. This Earth woman we must trust, for she can show us how to exist without wings, to survive and flourish. What should we do?

(Morton slaps the Doctor on the back)

MORTON: Hot diggety! I knew I was right. You should be wearing Police uniforms, you all is, you all is in a chase.

DOCTOR: Chase? Yes, as a matter of fact, young man, that's exactly what this is. Now, if you'll excuse me, I must be getting along. It's the chase, you know?

MORTON: Sure thing, Mister! I understand. Just wait til I tell the folks back home I met some real live movie pe- (knocks on TARDIS door) Do you know Cheyenne Bodie? Look, just wait a minute, I want to get this thing on celluloid.

(The TARDIS dematerialises)

MORTON: That's real clever, how they done that. Sure if it don't beat all.

BARBARA: What's that awful noise?

DOCTOR: I beg your pardon? awful noise? That's no way to talk about my singing!

BARBARA: No, Doctor, not that awful noise, the other one. Listen to it!

VICKI: Doctor? He says the TARDIS isn't a time machine.

DOCTOR: Oh, does he now?

VICKI: Tell him.

DOCTOR: I don't see why I should, my child. He'll learn soon enough.

STEVEN: Look, Doctor, I've seen some spaceships in my time, admittedly nothing like this. Well, what does this do?

DOCTOR: That is the dematerialising control and that, over yonder, is the horizontal hold. Up there is the scanner, those are the doors, that is a chair with a panda on it. Sheer poetry, dear boy. Now please stop bothering me.

STEVEN: All women?

MAAGA: Women?

DOCTOR: Yes, feminine. Ah, female.

MAAGA: Oh, we have a small number of men, as many as we need. The rest we kill. They consume valuable food and fulfill no particular function.

* (Maaga indicates the two Drahvins)*

MAAGA: And these are not what you would call human. They are cultivated in test tubes. We have very good scientists. I am a living being. They are products, and inferior products. Grown for a purpose and capable of nothing more.

STEVEN: Grown for what purpose?

MAAGA: To fight. To kill.

MALPHA: This is indeed an historic moment in the history of the universe. We six from the outer galaxies, joining with the power from the solar system, the Daleks! The seven of us represent the greatest war force ever assembled. Conquest is assured! Mars! Venus! Jupiter! The moon colonies!

BLACK: They will all fall before our might. But the first of them will be Earth!

ZENTOS: Doctor, for the fact that I mistrusted you, misjudged you, I'm sorry.

DOCTOR: Remember your journey is very important, young man, therefore you must travel with understanding as well as hope. Goodbye, Zentos.

ZENTOS: Goodbye Doctor.

DOCTOR: Oh, my dear Dodo, my dear Dodo. You know you're fast becoming a prey to every cliche-ridden convention in the American West. And it's high time we left. Now, come along.

STEVEN: Thank goodness for that.

DODO: What are my instructions?

(The machine makes some groaning noises and then finally produces coherent sounds.)

WOTAN: Doctor Who is required. Bring him here.

KRAIL: You must come and live with us.

POLLY: But we cannot live with you. You're, you're different. You've got no feelings.

KRAIL: Feelings? I do not understand that word.

DOCTOR: Emotions. Love, pride, hate, fear. Have you no emotions, sir?

KRAIL: Come to Mondas and you will have no need of emotions. You will become like us.

POLLY: Like you?

KRAIL: We have freedom from disease, protection against heat and cold, true mastery. Do you prefer to die in misery?

POLLY: You know, those dresses really do suit you, Doctor.

DOCTOR: Oh, you saucy girl.

KIRSTY: You're the very image of my old granny McLaren.

POLLY: You're wonderful, Doctor.

DOCTOR: I know.

BEN: The voices tell me what to do.

KLIEG: It's you. Over to that wall, all of you. All of you! Now.

DOCTOR: Yes, as you say, such a combination between intelligence and power would make you formidable indeed. Why you'd be commander of the universe with your brilliance! It makes the imagination reel with the possibilities!

KLIEG: Why, Doctor, if I had only known you shared my imagination, you might even have worked for me.

DOCTOR: Perhaps it's not too late?

JAMIE: Doctor!

DOCTOR: No, Jamie, don't you see?

(The Cybermen are waking but Klieg has his back to them.)

DOCTOR: Don't you see what this is going to all mean to all the people who come to serve Klieg the All Powerful? Why, no country, no person would dare to have a single thought that was not your own. Eric Klieg's own conception of the, of the way of life!

KLIEG: Brilliant! Yes, yes, you're right. Master of the world.

DOCTOR: Well now I know you're mad. I just wanted to make sure.

DOCTOR: Now, this won't take a minute. I just want to clean it off. Be as gentle as I can. There we are. Who are these men? Why are they so determined to kill us?

ASTRID: Kill you. They hate you.

DOCTOR: Me? I'm the nicest possible person.

DOCTOR: Oh, it's all right. You can relax. The electricity is off.

JAMIE: What was all that about?

DOCTOR: If there had been a current running through these rails, you'd have been fried!

JAMIE: Hey?

DOCTOR: Electrified. Brunched! Burnt up! Now, come along. It's safe now, I think, but we'd better be careful. Follow me.

DOCTOR: What's the matter, Victoria?

PRICE: She can't scream, sir.

DOCTOR: Oh no! Oh Victoria, that's ridiculous.

VICTORIA: Jamie, you can't scream just like that!

DOCTOR: Everything depends upon you screaming.

(Victoria screams.)

DOCTOR: There you are. I knew you could.

JAMIE: Doctor, come on, will ye? The whole place is going to blow up.

DOCTOR: Oh, it's quite all right, Jamie. The planet is quite safe. There's just going to be a localised volcanic eruption. It'll only affect the island.

JAMIE: Maybe so, but we happen to be on the island.

DOCTOR: Oh, my word!

DOCTOR: Which way, do you think?

ZOE: To the right.

DOCTOR: They both look equally unattractive to me.

ZOE: But it must be to the right. I've been working it out as we went along.

JAMIE: Doctor.

DOCTOR: Shush. How?

ZOE: Well, as soon as we avoided the dead ends, it soon fell into a clear pattern. One left, two right, three left, four right and so on. It's a simple arithmetic progression.

JAMIE: Yes, but Doctor.

DOCTOR: Shush, Jamie.

DOCTOR: What it is to have an arithmetical brain. What do you want?

JAMIE: The thread's run out. Now, should we not go back?

DOCTOR: No, you stay here.

JAMIE: Ah.

DOCTOR: And Zoe and I will explore a little further. There must be another way out of this maze and I mean to find it.

ISOBEL: Well, all I need is my cameras from the house and then I'm all set.

BRIGADIER: Now, wait a minute, This is hardly a job for you.

ISOBEL: Why ever not?

BRIGADIER: Well, you're a young woman. This is a job for my men.

ISOBEL: Well, of all the bigoted, anti-feminist, cretinous remarks-

BRIGADIER: This is no job for a girl like you. Now that's final.

ISOBEL: Oh, you, you, you man!

BRIGADIER: I'll get in touch with my photographic unit and get them onto it.

ISOBEL: Oh, that stupid bigoted idiotic-

JAMIE: Aye, well, he's right, you know.

ZOE: Jamie McCrimmon!

JAMIE: Well, he is.

ZOE: Just because you're a man you think that you're superior, do you?

JAMIE: Now, I didn't say that. Of course, it's true.

ZOE: Is it really? Right. Coming, Isobel?

ISOBEL: What a splendid idea.

JAMIE: Where are you going?

ZOE: Do you think we should let him come with us?

ISOBEL: Oh, I don't know. Men aren't much good in situations like this.

JAMIE: Just a moment. Where are you're going?

ISOBEL: London. Coming?

JAMIE: London? Now we shouldn't do anything without the Doctor! Och.

WATKINS: Vaughn, obviously I can't choose but to work for you. If I refuse, you'll torture me or kill me. I know I can't stand up to torture, and I don't want to die. You're an evil man, Vaughn. You're sadistic. You're a megalomaniac. You're insane. I pity you, but if I get half a chance, I'll kill you.

VAUGHN: Kill me? Would you? Give me your gun, Packer.

( Packer gives Vaughn his pistol. Vaughn points it at Watkin's head then turns it round and offers it to him.)

VAUGHN: Take it. There you are. Take it.

(Vaughn puts the gun in Watkins' hand. Gregory and Packer and the guard back away.)

VAUGHN: Now you're free to shoot me, Professor. Shoot. Shoot!

(Vaughn knocks Watkins down.)

VAUGHN: Come on, the gun's loaded, or haven't you got the courage to pull the trigger?

(Watkins gets up and fires three times, point blank, then faints. Vaughn has three smoking holes in his shirt, but is standing there laughing.)

VAUGHN: Take him away. Get work started on the machine immediately.

VAUGHN: Excellent.
