PERI: Do you think this wise, Doctor?

DOCTOR: My dear girl, if I stopped to question the wisdom of my actions, I'd never have left Gallifrey.

PERI: Sometimes I wish you hadn't.

PERI: Can we rest a moment? Oh, Doctor. Doctor!

YRCANOS: Open a vein. Let out the evil those devils have put into him.

PERI: Oh, it's Peri. Peri!

DOCTOR: So far up above myself on the table down below.

YRCANOS: Sorcerers. Evil demons. Soul stealers. They have my equerry Dorf in a dungeon somewhere. We must release him or die in the attempt. Were you captured by the slugs who rule this ball of mud and water?

PERI: Yes.

YRCANOS: We must find some weapons. Some of those that turn one's enemies to slime. We must kill all who stand between us and victory. We'll grind every last slug beneath our feet, yes?

PERI: Yes. Look, I just want to get out of here.
