ROMANA: Which way?

DOCTOR: Let’s go east.

ROMANA: How do you know which way is east?

DOCTOR: Well, I don’t. We'll go that way and call it east.

ROMANA: Why not call it north?

DOCTOR: All right, we'll call it north.

ROMANA: Northeast?

ROMANA: I’ve never met such idiots as those customs men.

DOCTOR: Idiots? They’re worse than idiots, they’re bureaucrats. They just exist to tangle people up, wrap them round and round in red tape until they can’t move.

ROMANA: Who needs a sonic screwdriver?

DOCTOR (to Leela): Lead the way, huntress.

ROMANA III: Gallifrey faces its darkest hour. Again.

HELEN: Liv?

LIV: Hm?

HELEN: You’ve done this more than I have. What’s the standard amount of time we leave it before we follow him?

LIV: About three minutes.

RIVER: That’s a drill, this is a gun. I win!

(Shooting noise)

RUSLAN: Argh!

RIVER: Oh I bet you are rubbish at scissors, paper stone!

THE SONOMANCER: I will not be questioned by a rogue, a renegade. One who runs from the responsibilities of our people.

DOCTOR: Responsibility? What’s responsible about genocide?

CALEERA: You are a firefly to my blazing sun!

FOURTH DOCTOR: I am essentially a pacifist. Though that does sometimes involve blowing things up.
