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.

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)
