Doctor: No second chances. I'm that sort of a man. (to the Sycorax gathering): By the ancient rites of combat, I forbid you to scavenge here for the rest of time. And when you go back to the stars and tell others of this planet, when you tell them of its riches, its people, its potential, when you talk of the Earth, then make sure that you tell them this: It is defended.
