MISSY: I am your friend.

DOCTOR: Makes no difference.

MISSY: I know it doesn't. I know I'm going to die. I have to say it, the truth. Without hope. Without witness. Without reward. I am your friend.

DOCTOR: Do you know a girl called Penny?

BILL: Well, yeah.

DOCTOR: What's she like?

BILL: Out of my league.

DOCTOR: No.

BILL: Sorry, what? No?

DOCTOR: No.

BILL: What does that mean, no?

DOCTOR: It means I'm a scary, handsome genius from space and I'm telling you no, she's not out of your league.

FIGURE: Greetings, sinner. Only in darkness are we revealed.

DOCTOR: I never sent for you.

FIGURE: Goodness is not goodness that seeks advantage. Good is good in the final hour, in the deepest pit without hope, without witness, without reward. Virtue is only virtue in extremis. This is what he believes, and this is the reason above all, I love him. My husband. My madman in a box. My Doctor.

(The figure is reading from a diary with a TARDIS-style cover. Then he pulls back the cowl to reveal himself.)

NARDOLE: Your missus wouldn’t approve.

DOCTOR: How the hell did you get here?

NARDOLE: Followed you from Darillium, on the explicit orders of your late wife, River Song. Warning, I have full permission to kick your arse.
