DOCTOR: In 900 years of time and space, I’ve never met anyone who wasn’t important.

DOCTOR: Goodbye, Jamie.

JAMIE: I won't forget you, you know.

DOCTOR: I won't forget you. Don't go blundering into too much trouble, will you?

JAMIE: Oh, you're a fine one to talk.

DOCTOR: Our lives are different to anybody else’s. That’s the exciting thing. There’s nobody in the universe can do what we’re doing.
