“Twice Upon a Time” quotes from Doctor Who

[Seeing her new face.] Oh, brilliant!

[as he takes in the TARDIS interior] Is this madness? Am I going mad?

Madness? Well, you're an officer from World War One at the South Pole being pursued by an alien through frozen time. Madness was never this good.

World War One?

Judging by the uniform, yes.

Yes, but what do you mean... "One"?

[realizing] Oh, sorry. Spoilers.

You… are me? No. No.

Yes. Yes, I'm very much afraid so.

Do I... become... you?

Well, there's a few false starts, but you get there in the end.

I thought...

What?

Well, I assumed I'd get... younger.

I am younger!

What's the matter?

I died a few hours ago and I refused to regenerate. Catches up with you, you know. It's like a big lunch.

I did exactly the same.

I know you did, but why? I don't remember this. Why are you refusing the regeneration?

Fear. I'm afraid. Very, very afraid. I don't normally admit that to anyone else.

Don't worry. Technically, you still haven't.

I adjusted the time frame, only by a couple of hours. Any other day, it wouldn't make any difference, but this is Christmas 1914... A human miracle is about to happen. The Christmas Armistice. It never happened again, any war, anywhere. But for one day, one Christmas, a very long time ago... everyone just put down their weapons... and started to sing. Everybody just stopped. Everyone... was just kind.

You've saved him!

Both of them. Never hurts, a couple fewer dead people on the battlefield.

So, that's what it means to be a Doctor of War...

You were right, you know. The universe generally fails to be a fairy tale... but that's where we come in!

Can't I ever have peace? Can't I rest?

Of course you can.

It's your choice.

Only yours.

We understand.

No. No, you don't. You're not even really here. You're just memories, held in glass. Do you know how many of you I could fill? I would shatter you. My Testimony would shatter all of you. A life this long -- do you understand what it is? It's a battlefield, like this one. It's empty. Because everyone else has fallen. Thank you. Thank you both, for everything that you were to me. What happens now... Where I go now.. has to be alone.

[prior to regeneration] Oh, there it is, silly old universe. The more I save it, the more it needs saving. It's a treadmill. Yes, yes, I know, they'll get it all wrong without me. Well, I suppose one more lifetime won't kill anyone. Well, except me. 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… 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. But nobody else. Nobody else, ever. Laugh hard. Run fast. Be kind. Doctor... I let you go.
