“We all change, when you think about it. We're all different people all through our lives. And that's okay, that's good, you've got to keep moving, so long as you remember all the people that you used to be. I will not forget one line of this. Not one day. I swear. I will always remember when the Doctor was me.”

“And now it's time for one last bow, like all your other selves. Eleven's hour is over now. The clock is striking twelve's.”

DOCTOR: Yaz, I can't fix myself to anything, anywhere or anyone. I've never been able to. That's what my life is.

YASMIN: Yeah, of course.

DOCTOR: Not because I don't want to, because I might. But if I do fix myself to somebody I know, sooner or later, it'll hurt.

DOCTOR: You look, er, amazing.

RIVER: Doctor, you have no idea whether I look amazing or not.

DOCTOR: Well, you've moved your hair about, haven't you?

RIVER: Well done. It's very sweet of you to try.

“You know what I said earlier about not being a bad date? Well, dates are not something I really do, you know. I mean, I used to. Have done. And if I was going to, believe me, it'd be with you. I think you're one of the greatest people I've ever known.”

CLARA: So, you must have thought I was dead for a while?

DOCTOR: Yeah.

CLARA: How was that?

DOCTOR: Longest month of my life.

CLARA: It could only have been five minutes.

DOCTOR: I'll be the judge of time.

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.
