DOCTOR: Oh, there it is. Silly old universe. The more I save it, the more it needs saving. It's a treadmill.

(TARDIS bleeps)

DOCTOR: Yes, yes I know they'll get it all wrong without me.

(TARDIS bleeps and lights flash)

DOCTOR: Well I suppose... One more lifetime.... Won't kill anyone.

(The Doctor's hands glow with regeneration energy)

DOCTOR: Well, except me.

(Cloister bell rings)

DOCTOR: You wait a moment, Doctor. Let's get it right. I've got a few things to say to you. Basic stuff first: Never be cruel, never be cowardly, and never ever eat pears! Remember, hate is always foolish, and love is always wise. Always try to be nice, but never fail to be kind. Oh! And, you mustn't tell anyone your name. No one would understand it anyway. Except-

(The Doctor collapses to the floor)

DOCTOR: Except children. Children can hear it. Sometimes, if their hearts are in the right place and the stars are too, children can hear your name.

(The Doctor pulls himself up on the TARDIS console, struggling)

DOCTOR: But nobody else. Nobody else. Ever.

(The Doctor manages to stand)

DOCTOR: Laugh hard. Run fast. Be kind. Doctor, I let you go.

(The Doctor regenerates)

DOCTOR: Who I am is where I stand. Where I stand is where I fall.

DOCTOR: Winning? Is that what you think it's about? I'm not trying to win. I'm not doing this because I want to beat someone, or because I hate someone, or because, because I want to blame someone. It's not because it's fun and God knows it's not because it's easy. It's not even because it works, because it hardly ever does. I do what I do, because it's right! Because it's decent! And above all, it's kind. It's just that. Just kind. If I run away today, good people will die. If I stand and fight, some of them might live. Maybe not many, maybe not for long. Hey, you know, maybe there's no point in any of this at all, but it's the best I can do, so I'm going to do it. And I will stand here doing it till it kills me. You're going to die too, some day. How will that be? Have you thought about it? What would you die for? Who I am is where I stand. Where I stand, is where I fall. Stand with me. These people are terrified. Maybe we can help, a little. Why not, just at the end, just be kind?

CLARA: No, listen, whatever happens next, wherever she is sending you, I know what you're capable of. You don't be a warrior. Promise me. Be a doctor.

DOCTOR: What's the point of being a doctor if I can't cure you?

CLARA: Heal yourself. You have to. You can't let this turn you into a monster so I'm not asking you for a promise. I'm giving you an order. You will not insult my memory. There will be no revenge. I will die and no one else here or anywhere will suffer.

DOCTOR: What about me?

CLARA: If there's something I could do about that, I would. Guess we're both just gonna have to be brave.

DOCTOR: Because every time you see them happy you remember how sad they’re going to be. And it breaks your heart. Because what’s the point in them being happy if they’re going to be sad later? The answer is, of course, because they are going to be sad later.

DOCTOR: In 900 years of time and space, I’ve never met anyone who wasn’t important.
