Rose Tyler: When you say 900 years…
Doctor: That’s my age.
Rose Tyler: You’re 900 years old.
Doctor: Yeah.
Rose Tyler: My mum was right. That is one hell of an age gap. Every conversation with you just goes mental. There’s no-one else I can talk to! I’ve seen all that stuff, up there, the size of it, and I can’t say a word. Aliens and spaceships and things… and I’m the only person on planet Earth who knows they exist.
From Doctor Who – Season 1 Episode 4: ‘Aliens of London’ (1×04)
