Donna: I'll tell you what we'll do though: Christmas dinner. (The Doctor is puzzled) Oh come on...
The Doctor: I don't do that sort of thing.
Dona: You did it last year, you said so. And you might as well since mum cooks enough for twenty.
The Doctor: oooh... (Struggles with his answer) Alright, but you go first, better warn them. And, don't say I'm a martian. (Donna laughs) I just gotta... park her (referring to the TARDIS) properly, she might... drift off to the middle ages. I'll see you in a minute. (Enters the TARDIS)
(Donna turns away, and turns back when she hears the sound of the TARDIS about to fade away)
Donna: Doctor! DOCTOR!!! (The TARDIS fades back)
The Doctor: Blimey, you can shout!
