The Doctor: Oh, just in time! C’mon, we’re going to the country. Fresh air and geniuses. What more could you ask.
Donna: I’m not coming with you. I’ve been thinking. I’m sorry. I’m going home.
The Doctor: Really?
Donna: I’ve got to.
The Doctor: Well. If that’s what you want. Only it’s a bit soon. I had so many places I wanted to take you. The fifteenth broken moon of the Medusa Cascade. The lightning skies of Cotter Palluni’s World. Diamond coral reefs of Kataa Flo Ko. Thank you. Thank you, Donna Noble. It’s been brilliant. You’ve… you’ve saved my life in so many ways. You’re… you’re just popping home for a visit, that’s what you mean.
Donna: You dumbo.
The Doctor: And then you’re coming back.
Donna: Know what you are? A great big, outer space dunce.
The Doctor: Yeah.
