ROMANA: How long am I going to be tied up here?

ROHM-DUTT: Well, that depends.

ROMANA: On what?

ROHM-DUTT: On whether you cooperate. If you don't, you'll rot there. Won't take long in this climate.

ROMANA: And that doesn't bother you?

ROHM-DUTT: Young woman, I'm indifferent.

ROMANA: Emotional insulation is usually indicative of psychofugal trauma.

ROHM-DUTT: I didn't know that.

THAWN: Don't you worry about the Swampies. We'll look after them, provided they see reason.

DOCTOR: What, teach them to carry trays?

FENNER: Why not? Tell me, would you let a small band of semi-savages stand in the way of progress?

DOCTOR: Well, progress is a very flexible word. It can mean just about anything you want it to mean.
