Rose: No signal. That’s the first time I’ve gone out of range. Mind you, even if I could… what would I tell her? Can you build another TARDIS?
The Doctor: They were grown, not built. And with my home planet gone we’re kind of stuck.
Rose: Well, could be worse. This lot said they’d give us a lift.
The Doctor: And then what?
Rose: I don’t know. Find a planet. Get a job. You live a life same as the rest of the Universe.
The Doctor: I’d have to settle down. Get a house or something, a proper house. With… doors and carpets. Me, living in a house. That, that, is terrifying.
Rose: You’d have to get a mortgage.
