DOCTOR: I’ve seen Slake and the others now. They don’t deserve to be kept alive. Not at the cost of other’s suffering and death.

SAM: Isn’t that my line?

DOCTOR: Of course, you were right.

SAM: But what about all that stuff you were saying, about everyone having the right to live-

DOCTOR: Oh, that’s right as well.

HARRIS: But they completely contradict each other?

DOCTOR: You’re right too. Now all you need to do is figure out how we can all be right at the same time, then you’ll have it.

DOCTOR: What do you want me to be? Someone who knows exactly what he’s doing and has it all under control, or just some fellow who makes it up as he goes along, and still makes it happen? Which do you want it to be? Magic tricks, or magic?
