MASTER: I hope I'm not interrupting anything important.

DOCTOR: No, no, indeed not. You've come here to kill me, of course.

MASTER: But not without considerable regret.

DOCTOR: How very comforting.

MASTER: You see, Doctor, you're my intellectual equal. Almost. I have so few worth opponents. When they've gone, I always miss them.

DOCTOR: How did you get in here?

MASTER: Oh, don't be trivial, Doctor. I see you've been working on the Nestene autojet. My own small contribution to their invasion plan.

DOCTOR: Vicious, complicated and inefficient. Typical of your way of thinking.

MASTER: Now, come, come, Doctor. Death is always more frightening when it strikes invisibly.

DOCTOR : Injustice is the rule, but I want justice. Suffering is the rule, but I want to end it. Despair accords with reality, but I insist on hope. I don't accept it because it is unacceptable. I say no.
