RUTH: (To the Thirteenth Doctor) Have you ever been limited by who you were before?

KO SHARMUS: You can be a pacifist tomorrow. Today, you have to survive.

MASTER: Look upon my work, Doctor, and despair. Remember how we used to run through those streets as children? The alleys where we'd hide from Borusa as we skipped classes? All gone now. Come on, ask me why I did this.

DOCTOR: Why did you do this?

MASTER: Not telling you. (laughs) Oh, crack a smile.

DOCTOR: Proud of yourself?

MASTER: Definitely.

DOCTOR: All this death finally made you happy?

MASTER: Ecstatic.

DOCTOR: And has it calmed all the rage?

MASTER: I don't think anything will ever do that.

MASTER: I wish it wasn't true, but it is. You know what I find the most infuriating? You always behaved like you were different, like you were... like you were special. And you were. You can see... you can see why I'm angry. A little piece of you is in me. All I am is somehow because of you, and believe me when I say, I cannot bear that.

DOCTOR: Whatever you want with me, fine. But save my friends. Don't let the Cybermen take them. If the history between us means anything to you...

MASTER: I do believe you're appealing to my better nature. And we both know I don't have one. I'm not going to help them, and neither are you. And the history between us does mean something. It's the rage and pain in my hearts.
