Oswin: Oswin Oswald. Junior Entertainment Manager, Starship Alaska. Current status: crashed and shipwrecked somewhere... not nice. Been here a year, rest of the crew missing. Provisions good, but keen to move on.
The Doctor: A year? Are you okay? Are you under attack?
Oswin: Some local lifeforms. Been keeping them out.
The Doctor: Do you know what those lifeforms are?
Oswin: I know a Dalek when I hear one, yeah.
The Doctor: What have you been doing on your own against the Daleks for a year?
Oswin: Making soufflés?
The Doctor: Soufflés. Against the Daleks.
