CYBERMAN: Love is not a mission. Love is an emotion. Emotions are not missions.

BEL: And that's why you're dead on floor, and I put you there. (shoots it again) Love is the only mission. Idiot.

CLARA: Do you hear me? I did this. This is my fault.

DOCTOR: I don't care!

CLARA: Liar. You always care. Always have. Your reign of terror will end with the sight of the first crying child and you know it.

DOCTOR: I don't.

CLARA: I do.

DOCTOR: I’m old enough to know that a longer life isn’t always a better one. In the end, you just get tired; tired of the struggle, tired of losing everyone that matters to you, tired of watching everything you love turn to dust. If you live long enough, Lazarus, the only certainty left is that you’ll end up alone.

DOCTOR: Hello.

DAVID: Get back or I'll use the gun.

DOCTOR: Yes, I imagine you will. You like guns, don't you.

DAVID: This is a specialised weapon. It's designed for roof duty, designed for long range. I've never used one up close before.

ALEX: Let him go.

DAVID: No.

DOCTOR: No. In fact, let him come a little closer.

DAVID: Stay where you are.

DOCTOR: Why? Scared? Why should you be scared? You're the one with the gun.

DAVID: That's right.

DOCTOR: You like guns, don't you.

ALEX: He'll kill you.

DOCTOR: Of course he will. That's what guns are for. Pull the trigger, end a life. Simple, isn't it.

DAVID: Yes.

DOCTOR: Makes sense, doesn't it.

DAVID: Yes.

DOCTOR: A life killing life.

ALEX: Who are you?

DOCTOR: Shut up. Why don't you do it then? Look me in the eye, pull the trigger, end my life. Why not?

DAVID: I can't.

DOCTOR: Why not?

DAVID: I don't know.

DOCTOR: No, you don't, do you.

(The Doctor takes the gun from David.)

DOCTOR: Throw away your gun.

(Alex drops his gun.)

LARRY: Phil? Phil, it’s Larry. Your brother Larry. Think, Phil! Remember me!

PHIL: You are both runaways.

LARRY: Angela. Your wife, Angela! I’ll take you to her.

PHIL: You must both be punished.

IAN: It’s no good, Larry.

LARRY: No, no! No, Ian!

IAN: Come on!

LARRY: Ian, get clear. Run while you’ve got the chance! Run, Ian. Run.

(Larry throttles Phil while Phil shoots Larry)

LARRY: Run, Ian, run.

PHIL: Larry.

(They die, and the alarm goes off)
