DOCTOR: Yeah, two minutes, no lingering. Plenty more universe to see and, quite frankly, your lifespan sucks.

DOCTOR: I'm a much bigger bang than you bargained for. I'm a lot more explosive than I look, and honey... I know how I look. Put a quantum chain reaction through me and I will shatter this silly little battlefield of yours into dust. All of it, in a heartbeat, into dust.

RUBY: Is that a monster?

DOCTOR: No. No, don't be silly, Ruby. There's no such thing as monsters, there's just... just creatures you haven't met yet.

RUBY: We made it. The human race, we survived. We went to the stars. And ten minutes ago, Doctor, just ten minutes ago, you said genocide. Your people are gone.

DOCTOR: Yeah.

RUBY: How do you keep going?

DOCTOR: For days like this, Ruby Sunday. I don't have a people. I don't have a home. But I don't have a job, either. I don't have a boss, or taxes or rent or bills to pay. I don't have a purpose or a cause, or a mission, but I have... ..freedom. And so I keep moving on, to see the next thing, and the next, and the next. And sometimes... it looks even better through your eyes.

DOCTOR: And do you want to know my secret? There's no one like me in the whole wide universe. No one like me exists, and that's true of everyone. It's not a problem, Captain Pops. It's a superpower.

DOCTOR: Okay. Name - the Doctor. Occupation - not a doctor. Current status - just passing by. Employer - myself. Address - that blue box over there. Now, if you don't mind, I just got snowmanned, and I would like to go home.

14th Doctor: You're me.

15th Doctor: No, I'm me. I think I'm really, really me. Oh, ho-ho, I am completely me! Don't just stand there, push!

15th DOCTOR: Look after him, you know? Now, you two, if you don't mind, there is a great big universe out there calling, and I've got to get going. So off you pop, old man.

14th DOCTOR: Oh. You're the old man. You're older than me.

DONNA: Actually, that is true. He's younger because you came after him. So you're the older Doctor.

15th DOCTOR: Okay, kid. I love you. Get out!

TOYMAKER: I have fallen in love with humanity. This world is the ultimate playground. All of the sport, the matches, the medals, the gambling and the anger and the children shackled to their bedrooms with their joysticks and their buttons. You make games out of bricks falling upon other bricks. You are exceptional. And then there are the mind games. Oh, the dating and ghosting, the deceit and the control. You make me dizzy. I am in no hurry to leave this place.

DOCTOR: Oh, the blossomiest blossom. That's the only sad thing. I want to know what happens next. Right, then. Doctor Whoever-I'm-about-to-be. Tag, you're it.

DOCTOR: Words matter! One death, one ripple, and history will change in a blink. The future will not be the world you know. The world you came from, the world you were created in won't exist, so neither will you.

DOCTOR: Cos sometimes this team structure isn't flat. It's mountainous, with me at the summit in the stratosphere, alone, left to choose.

DOCTOR: Come on, please. Give us this. It's all right, it's me! Stabilise. Come to Daddy. I mean Mummy.

DOCTOR: Bit of adrenaline, dash of outrage, and a hint of panic knitted my brain back together. I know exactly who I am. I'm the Doctor. Sorting out fair play throughout the universe. Now please, get off this planet while you still have a choice.

DOCTOR: When people need help, I never refuse.

DOCTOR: We’re all capable of the most incredible change. We can evolve while still staying true to who we are. We can honour who we’ve been and choose who we want to be next. Now’s your chance. How about it?

DOCTOR: Why are you calling me madam?

YASMIN: Because you're a woman.

DOCTOR: Am I? Does it suit me?

YASMIN: What?

DOCTOR: Oh yeah, I remember. Sorry, half an hour ago I was a white-haired Scotsman.

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?

MASTER: Well hello then young lady, I’m called the Master. Don’t listen to a word he says about me. He’ll make all these terrible claims saying I’ve done this; caused that; murdered these people; eradicated this species, but don’t believe any of it. In reality I am far, far worse.

DOCTOR: I don't need authority! I have a SCREWDRIVER!

MASTER: The title you chose: Doctor. Now, it’s not just a man of healing. It means “teacher”. It means “tutor”. Whereas I am a Master. We both want to change the universe, to make it better, it’s only the scale of our ambition separates us.

DOCTOR: What are you saying? You’d like to have been a Doctor but you didn’t have the patients?

DOCTOR: I'm a doctor. But probably not the one you're expecting.

DOCTOR: Charley, C'Rizz, Lucie, Tamsin, Molly. Friends, companions I've known, I salute you. And Cass, I apologise. Physician, heal thyself.

DOCTOR: I was once a man with a masterplan. I’d seek out injustices, topple governments, all in the name of the greater good. I’d started doing the maths, you see…. This is how evil starts, with the belief that the ends justify the means. But once you start down that road, there’s no turning back. What if you can save a million lives, but you have to let ten people die, or a hundred, or a hundred thousand. Where do you stop?
