DOCTOR: Of course we should interfere. Always do what you’re best at, that’s what I say.

RIGG: Yes, but who do you work for?

DOCTOR: Work for? I don't work for anybody. I'm just having fun.

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.

CAPTAIN RIGG: It's totally inexplicable!

DOCTOR: Nothing's inexplicable.

CAPTAIN RIGG: Then explain it!

DOCTOR: ... It's inexplicable.

CAPTAIN RIGG: Yes, and I'd like to know just who you are.

DOCTOR: Me? I told you, I'm from Galactic.

CAPTAIN RIGG: Galactic went out of business twenty years ago.

DOCTOR: I wondered why I hadn't been paid.

OFFICER COSTA: Name and date of birth?

DOCTOR: Well how would I know? I don't even know who he is yet!

OFFICER COSTA: Your name and date of birth.

DOCTOR: Oh, well, I'm called the Doctor. Date of birth, difficult to remember. Sometime quite soon, I should think.

ROMANA: How many were on your ship?

TRYST: Ah, well, to begin with there was ten, but we lost one.

ROMANA: How?

TRYST: He died.

ROMANA: How did he die?

TRYST: He died.
