Doctor: Right. Where d'you want to start?
Rose Tyler: Um... The inside's bigger than the outside.
Rose Tyler: It's... alien.
Rose Tyler: Are you alien?
Doctor: Yes. Is that all right?
Rose Tyler: Yeah.
Rose Tyler: But who is he? Who d'you think he is?
Clive: I think he's the same man. I think he's immortal. I think he's an alien from another world.
Clive: The Doctor is a legend, woven throughout history. When disaster comes, he's there. He brings the storm in his wake, and has one constant companion.
Rose Tyler: Who's that?
Clive: Death. If the Doctor's back, if you've seen him, Rose, one thing's for certain. We're all in danger. If he singled you out, if the Doctor's making house calls... then God help you.
Rose Tyler: Really, though, Doctor... Tell me. Who are you?
Doctor: Do you know like we were saying? About the Earth revolving? It's like when you're a kid. The first time they tell you the world's turning and you can't believe it cos it looks like everything's standing still... I can feel it. (takes her hand) The turn of the Earth. The ground beneath our feet is spinning at 1,000 miles an hour. The entire planet is hurtling round the sun at 67,000 miles an hour. 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... (lets go of her hand) That's who I am. Now forget me, Rose Tyler. Go home.
Doctor: What are you doing here?
Rose Tyler: I live here.
Doctor: What do you do that for?
Rose Tyler: 'Cos I do!
Rose Tyler: You pulled his arm off!
Doctor: Yep, plastic.
Rose Tyler: Very clever, nice trick. Who are they, students? A student thing?
Doctor: Why would they be students?
Rose Tyler: I don't know!
Doctor: You said it. Why students?
Rose Tyler: 'Cos... to get that many people dressed up and being silly they got to be students.
Doctor: That makes sense. Well done.
Rose Tyler: Thanks.
Doctor: They're not students.
