DOCTOR: I saw the Fall of Troy! World War Five! I pushed boxes at the Boston Tea Party, and now I'm gonna die in a dungeon... in Cardiff!

ROSE: But, it's like, think about it, though. Christmas. 1860. Happens once, just once and it's gone, it's finished, it'll never happen again. Except for you. You can go back and see days that are dead and gone a hundred thousand sunsets ago. No wonder you never stay still.

DOCTOR: You think it'll last forever, people and cars and concrete, but it won't. One day it's all gone. Even the sky. My planet's gone. It's dead. It burned like the Earth. It's just rocks and dust before its time.

ROSE: What happened?

DOCTOR: There was a war and we lost.

ROSE: A war with who? What about your people?

DOCTOR: I'm a Time Lord. I'm the last of the Time Lords. They're all gone. I'm the only survivor. I'm left travelling on my own 'cos there's no one else.

ROSE: There's me.

DOCTOR: You lot, you spend all your time thinking about dying, like you're going to get killed by eggs or beef or global warming or asteroids. But you never take time to imagine the impossible, that maybe you survive. This is the year five point five slash apple slash twenty six. Five billion years in your future, and this is the day- hold on - this is the day the Sun expands. Welcome to the end of the world.

ROSE: You think you're so impressive.

DOCTOR: I am so impressive.

ROSE: You wish.

ROSE: If you are an alien, how comes you sound like you're from the North?

DOCTOR: Lots of planets have a North.

DOCTOR: I'm the Doctor, by the way. What's your name?

ROSE: Rose.

DOCTOR: Nice to meet you, Rose. Run for your life!

ROSE: Hold on a minute. You can't just go swanning off.

DOCTOR: Yes I can. Here I am. This is me, swanning off. See you.

ROSE: But that arm was moving. It tried to kill me.

DOCTOR: Ten out of ten for observation.

CLIVE: The Doctor is a legend woven throughout history. When disaster comes, he's there. He brings the storm in his wake and he has one constant companion.

ROSE: Who's that?

CLIVE: Death.

DOCTOR: Do you know like we were saying about the Earth revolving? It's like when you were a kid. The first time they tell you the world's turning and you just can't quite believe it because everything looks like it's standing still. I can feel it. The turn of the Earth. The ground beneath our feet is spinning at a thousand miles an hour, and the entire planet is hurtling round the sun at sixty seven thousand miles an hour, and I can feel it. We're falling through space, you and me, clinging to the skin of this tiny little world, and if we let go. That's who I am. Now, forget me, Rose Tyler. Go home.

IAN: It may only be a small opening. Don't count on it.

DOCTOR: Well you obviously are.

IAN: Of course I am. Any hope is better than none. Don't just lie there criticizing us. Do something. Help us all to get out of here.

SUSAN: Grandfather, we can make friends with them.

DOCTOR: Oh, don't be ridiculous, child.

BARBARA: Why? You treat everybody and everything as something less important than yourself.

DOCTOR: I tolerate this century, but I don't enjoy it. Have you ever thought what it's like to be wanderers in the fourth dimension? Have you? To be exiles? Susan and I are cut off from our own planet, without friends or protection. But one day we shall get back. Yes, one day. One day.

KAL: Za killed the old woman with his knife.

HUR: No.

KAL: Here. Here is the knife he killed her with.

DOCTOR: This knife has no blood on it. I said, this knife has no blood on it.

KAL: It is a bad knife. It does not show the things it does.

DOCTOR: It is a finer knife than yours.

KAL: I, Kal, say it is a bad knife.

DOCTOR: This knife can cut and stab. I have never seen a better knife.

KAL: I will show you one.

(Kal pulls out his flint knife)

DOCTOR: This knife shows what it has done. There is blood on it. (to Za) Who killed the old woman?

ZA: I did not kill her.

DOCTOR: (to Kal) You killed the old woman.

KAL: Yes! She set them free. She set them free. She did this. I, Kal, killed her.

DOCTOR: Is this your strong leader? One who kills your old women? He is a bad leader. He will kill you all.

BARBARA: Are you saying you don't know how to work this thing?

DOCTOR: Of course I can't! I'm not a miracle worker!

SUSAN: The TARDIS can go anywhere.

BARBARA: TARDIS? I don’t understand you, Susan.

SUSAN: Well, I made up the name TARDIS from the initials, Time And Relative Dimension In Space. I thought you’d both understand when you saw the different dimensions inside from those outside.

IAN: Just let me get this straight. A thing that looks like a police box, standing in a junkyard, it can move anywhere in time and space?

SUSAN: Yes.

DOCTOR: Quite so.

IAN: But that’s ridiculous.

DOCTOR: Fear makes companions of all of us.

DOCTOR: If you could touch the alien sand and hear the cries of strange birds and watch them wheel in another sky, would that satisfy you?

DOCTOR: It's still a police box. Why hasn't it changed? Dear, dear, how very disturbing.
