DOCTOR: I'm not a Chuldur. I'm something much older and far more powerful. I'm a Lord of Time from the lost and fallen planet of Gallifrey. Now, let me go, bounty hunter. We have work to do.

DOCTOR: Rogue, I am telling you, you've got the wrong man, okay? And I can prove it. This authenticates me as non-Chuldur.

(Psychic paper.)

ROGUE: It says you're hot.

DOCTOR: Does it? I'm sorr... No, it's broken.

ROGUE: Is it you're hot, or I'm hot?

DOCTOR: No, it is just that it's...

ROGUE: Who's hot, Doctor?

DOCTOR: It means the temperature.

ROGUE: It suits you, flustered. It's a good look. You should try it more often.

DOCTOR: You lost someone.

ROGUE: How do you know that?

DOCTOR: Because I know.

ROGUE: There was... Yeah. We travelled together. We had fun, y'know? And then a day came along, and at the end of that day... I lost them. What about you?

DOCTOR: I lost everyone.

ROGUE: At the party, I saw you with that woman.

DOCTOR: Mmm. My best friend.

ROGUE: Do you ever wonder... why keep going?

DOCTOR: Because we have to. We have to live each day because they can't. You don't have to stay a bounty hunter, Rogue. You could travel with me. Oh, the worlds I could show you, Rogue.

ROGUE: And what if I like what I do? Would you travel with me?

DOCTOR: That is quite an argument. I'll tell you what. When we both get out of this, let's argue across the stars.

ROGUE: I'd like that.

DOCTOR: I don't care what you think. And you can say whatever you want. You can think absolutely anything. I will do anything if you just allow me to save your lives.

BREWSTER: If you'll turn away, ladies, before you're contaminated.

DOCTOR: You will die out there! And I can save your lives! Now let me!

SARAH: I'm not just gonna wait for him to get killed. I don't care if he's a weirdo. And he is. He is a weirdo, you know, but he's decent. And he's got a good heart. My friend Lauren actually says that good-hearted weirdos are actually the keepers, so...

(Yaz looks at the Doctor)

DOCTOR: What?

YASMIN: No, nothing.

DOCTOR: Time loop.

YASMIN: Time loop.

DAN: Groundhog Day. Same difference.

YASMIN: It felt cruel... to be shown something I couldn't have any more. Felt like, er, I'd rather not have known. I'd rather not have met her, cos having met her and then... being without her, that's worse. How do you deal with that?

HARKNESS: When I was with the Doctor, I saw more than I could have ever dreamed. And then... we lost each other. I didn't know what happened to him. If he was alive or... if I was ever going to see him again. Hard way to live. Being with the Doctor, you don't get to choose when it stops. Whether you leave her or... she leaves you.

HARKNESS: How many people in the universe get to meet the Doctor, let alone travel with her? We're the lucky ones, Yaz. Enjoy the journey while you're on it. Cos the joy... is worth the pain.

ROMANA: Oh, I do love the spring. All the leaves, the colours.

DOCTOR: It's October.

ROMANA: I thought that you said we were coming here for May week.

DOCTOR: I did. May week's in June.

ROMANA: I'm confused.

DOCTOR: So was the TARDIS.

ROMANA: Oh, I do love the autumn. All the leaves, the colours.

NARDOLE: Don’t die. Because if you do, I think everybody in the universe might just go cold.

DOCTOR: Never be cruel. Never be cowardly. Hate is always foolish. Love is always wise. Always try to be nice, but never fail to be kind.

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: Human progress isn't measured by industry, it's measured by the value you place on a life. An unimportant life. A life without privilege. The boy who died on the river, that boy's value is your value. That's what defines an age. That's what defines a species.

CLARA: I don't think I could ever forget you.

DOCTOR: Clara, I don't think you're ever going to have to.

CLARA: No. Why would you even do that? I was dead! I was dead and gone. Why? Why would you even do that to yourself?

DOCTOR: I had a duty of care.

DOCTOR: A long time ago, there was a student at the Academy. He got in here, disappeared for four days. Showed up in a completely different part of the city. Said the Sliders talked to him, they showed him the secret passage out. And we just need the code.

CLARA: What, and the kid told you the secret?

DOCTOR: Ah, no, he didn't tell anyone anything. He went completely mad, never right in the head again. So they say. Last I heard, he stole the moon and the President's wife.

CLARA: Was she... Was she nice, the President's wife?

DOCTOR: Ah well, the was a lie put about by the Shabogans. It was the President's daughter. I didn't steal the moon, I lost it...

CLARA: I'd know you anywhere.

CLARA: Doctor, you are not the only person who ever lost someone. It's the story of everybody. Get over it. Beat it. Break free. 

(Her hand touches his cheek.)

CLARA: Doctor, it's time. Get up, off your arse, and win!

DOCTOR: If you think because she is dead I am weak, then you understand very little. If you were any part of killing her, and you're not afraid, then you understand nothing at all. So, for your own sake, understand this. I am the Doctor. I'm coming to find you, and I will never, ever stop.

DOCTOR: I didn't leave Gallifrey because I was bored! That was a lie, that has always been a lie!

(The Veil continues approaching)

DOCTOR: Not enough? You want more?

(The Veil continues approaching)

DOCTOR: I was scared! I ran because I was scared! Is that what you want me to say? Is that true enough for you?

DOCTOR: There's this emperor and he asks this shepherd's boy, how many seconds in eternity? And the shepherd's boy says there's this mountain of pure diamond. It takes an hour to climb it, and an hour to go around it! Every hundred years, a little bird comes and sharpens its beak on the diamond mountain. And when the entire mountain is chiselled away, the first second of eternity will have passed! You must think that's a hell of a long time. Personally, I think that's a hell of a bird.

DOCTOR: As you come into this world, something else is also born. You begin your life, and it begins a journey towards you. It moves slowly, but it never stops. Wherever you go, whatever path you take, it will follow. Never faster, never slower, always coming. You will run. It will walk. You will rest. It will not. One day, you will linger in the same place too long. You will sit too still or sleep too deep, and when, too late, you rise to go, you will notice a second shadow next to yours. Your life will then be over.

DOCTOR: I can't! Why is it always me? Why is it never anybody else's turn? Can't I just lose? Just this once?

CLARA: Do you hear me? I did this. This is my fault.

DOCTOR: I don't care!

CLARA: Liar. You always care. Always have. Your reign of terror will end with the sight of the first crying child and you know it.

DOCTOR: I don't.

CLARA: I do.
