Emperor Dalek: Explain yourself.
The Doctor: I said no.
Emperor Dalek: What is the meaning of this negative?
The Doctor: It means no!
Emperor Dalek: But she will be destroyed!
The Doctor: No! 'Cause this is what I'm gonna do - I'm gonna rescue her! I'm gonna save Rose Tyler from the middle of the Dalek fleet, and then I'm gonna save the Earth, and then - just to finish you off - I'm gonna wipe every last stinking Dalek out of the sky!
Emperor Dalek: But you have no weapons, no defences, no plan!
The Doctor: Yeah, and doesn't that scare you to death?

Doctor: Rose...Before I go, I just wanna tell you, you were fantastic. Absolutely fantastic. And d'you know what? So was I.
Chosen answer: The Master knows that deep down, he deserves death for the crimes that he's committed throughout his life, and since he regards The Doctor as his arch-foe, he expects it to be at his hands. The fact that The Doctor is still willing to forgive him for all of his crimes hurts him more deeply than death would.
