- The Doctor: [to himself about the TARDIS] It's still a police box! Why hasn't it changed? Dear, dear - how very disturbing!
- Susan Foreman: We've left 1963.
- The Doctor: Oh, yes, undoubtedly. I'll be able to tell you where presently. Zero? That's not right. I'm afraid this yearometer is not calculating properly. Hm! Well, anyway, the journey's finished.
- [looking at Ian on the ground]
- The Doctor: What are you doing down there?
- Barbara Wright: What have you done?
- Ian Chesterton: Barbara, you don't believe all this nonsense.
- Susan Foreman: Well, look at the scanner screen.
- The Doctor: Yes, look up there. They don't understand and I suspect they don't want to. Well, there you are. A new world for you.
- Ian Chesterton: Sand and rock?
- The Doctor: Yes. That's the immediate view outside the ship.
- Barbara Wright: But where are we?
- Ian Chesterton: You mean that's what we'll see when we go outside?
- Susan Foreman: Yes, you'll see it for yourself.
- Ian Chesterton: I don't believe it.
- The Doctor: You really are a stubborn young man, aren't you?
- Ian Chesterton: All right, show me some proof. Give me some concrete evidence. I'm sorry, Susan. I don't want to hurt you, but it's time you were brought back to reality.
- Susan Foreman: But you're wrong, Mr. Chesterton.
- The Doctor: They are saying I'm a charlatan. What concrete evidence would satisfy you? Hmm?
- Ian Chesterton: Just open the doors, Doctor Foreman.
- The Doctor: Eh? Doctor who? What are you talking about?
- Ian Chesterton: Just a minute. You say we've gone back in time?
- The Doctor: Yes, quite so.
- Ian Chesterton: So that when we go out of that door, we won't be in a junkyard in London in England in the year 1963?
- The Doctor: That is quite correct. But your tone suggests ridicule.
- Ian Chesterton: But it is ridiculous. Time doesn't go round and round in circles. You can't get on and off whenever you like in the past or the future.
- The Doctor: Really? Where does time go, then?
- Ian Chesterton: It doesn't go anywhere. It just happens and then it's finished.
- The Doctor: [to a skeptical Ian] 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?
- Susan Foreman: It should have changed. Wonder why it hasn't happened this time.
- Barbara Wright: The ship, you mean?
- Susan Foreman: Yes, it's been an Ionic column and a sedan chair.
- Barbara Wright: Disguising itself wherever it goes.
- Susan Foreman: Yes, that's right. But it hasn't happened this time. I wonder why not?
- Barbara Wright: You're very quiet.
- Ian Chesterton: I was wrong, wasn't I?
- Barbara Wright: Oh, look, I don't understand it anymore than you do. The inside of the ship, suddenly finding ourselves here. Even some of the things Doctor Foreman says...
- Ian Chesterton: That's not his name. Who is he? Doctor who? Perhaps if we knew his name, we might have a clue to all this.
- Ian Chesterton: Strange.
- Barbara Wright: What?
- Ian Chesterton: This sand. It's cold. It's nearly freezing.
- Za: It's good to have someone to laugh at!
- The Doctor: I'm sorry, it's all my fault. I'm desperately sorry.
- Susan Foreman: Don't blame yourself grandfather.
- The Doctor: Look at that. Look at it.
- Ian Chesterton: They're all the same... They've been split wide open.
