DOCTOR: This is Clara, not my assistant. She's, er, some other word.

CLARA: I'm his carer.

DOCTOR: Yeah, my carer. She cares so I don't have to.

RUSTY: I see your mind, Doctor. I see your universe.

DOCTOR: And isn't the universe beautiful?

RUSTY [OC]: I see beauty.

DOCTOR: Yes, that's good. That is good. Hold on to that.

RUSTY [OC]: I see endless, divine perfection.

DOCTOR: Make it a part of you. Remember how you feel right now. Put it inside you and live by it.

RUSTY [OC]: I see into your soul, Doctor. I see beauty. I see divinity. I see hatred.

DOCTOR: Hatred?

RUSTY: I see your hatred of the Daleks and it is good.

DOCTOR: No, no, no. You must see more than that, there must be more than that.

RUSTY: Death to the Daleks. Death to the Daleks. Death to the Daleks.

DOCTOR: No, there must be more than that. There must be more than that. Please.

RUSTY: Daleks are evil. Daleks must be exterminated. Daleks are evil.

(Rusty approaches his former comrades from the rear, while Morgan and his surviving soldiers prepare for them to break through the bulkhead door.)

MORGAN: God save us all.

RUSTY: Daleks must be exterminated.

(The Daleks turn and Rusty shoots them to pieces.)

RUSTY: Exterminate.

DALEK: Under attack from a Dalek!

(KaBOOMs all round!)

RUSTY: The Daleks are exterminated.

[Rusty's mind]

DOCTOR: Of course they are. That's what you do, isn't it?
