DOCTOR: I'm a doctor. But probably not the one you're expecting.

OHILA: We restored you to life, but it's a temporary measure. You have a little under four minutes.

DOCTOR: Four minutes? That's ages. What if I get bored? I need a television, couple of books, anyone for chess? Bring me knitting.

DOCTOR: Charley, C'Rizz, Lucie, Tamsin, Molly. Friends, companions I've known, I salute you. And Cass, I apologise. Physician, heal thyself.

DOCTOR: Doctor no more.

DOCTOR: I don't suppose there's any need for a Doctor, anymore. Make me a warrior, now.

CASS: Is this a TARDIS?

DOCTOR: Yes, but you'll be perfectly safe, I promise you.

CASS: Don't touch me!

DOCTOR: I'm not part of the war. I swear to you, I never was.

CASS: You're a Time Lord.

DOCTOR: Yes, I'm a Time Lord, but I'm one of the nice ones.
