DOCTOR: There are worlds out there where the sky is burning, where the sea's asleep, and the rivers dream. People made of smoke, and cities made of song. Somewhere there's danger, somewhere there's injustice, and somewhere else the tea's getting cold. Come on, Ace, we've got work to do!

ACE: Master? Who's he?

DOCTOR: An evil genius. One of my oldest and deadliest of enemies.

ACE: Do you know any nice people? You know, ordinary people, not power-crazed nutters trying to take over the galaxy?

ACE: I felt like I could run forever, like I could smell the wind and feel the grass under my feet and just run forever.

DOCTOR: If we fight like animals, we'll die like animals!
