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 Tyler: What happened?
Doctor: There was a war, and we lost.
Rose Tyler: 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 Tyler: There's me.
Doctor: You've seen how dangerous it is. D'you wanna go home?
Rose Tyler: I don't know. I want... Can you smell chips?
Doctor: Yeah. Yeah!
Rose Tyler: I want chips.
Doctor: Me too.
Rose Tyler: Right, then. Before you get me back in that box, chips it is. And you can pay.
Doctor: No money.
Rose Tyler: What sort of date are you? Come on, then, tightwad. Chips are on me.
