“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.”

“Nothing’s sad until it’s over, and then everything is.”

“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?”

“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.”

“Who I am is where I stand. Where I stand is where I fall.”

“Do you know what thinking is? It’s just a fancy word for changing your mind.”

“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.”

DAN LEWIS: I've only been back a month, and I've got to say, I'm glad I'm not on the verge of being exterminated any more. But I do miss her.

IAN CHESTERTON: Sorry. Did you say her?

“You know what I think? I think it's not over, because I don't think she's dead. I really don't. That's not just me being mad, cos I honestly think in my heart and soul that he came back for her. Right at the end, the Doctor came back for his Sarah Jane, and he said, shall we go? Out into the stars? One last trip? And she said, oh yes please. And I think they're out there now, Sarah Jane and the Doctor in the TARDIS, travelling through space and time forever, in a story that never ends.”

“She's the one who told me that Sanjay was looking at me in that way, and she's the one who told me to go and talk to him. And now we've been married for five years. That's the greatest gift she ever gave me. I may have been created by the Bane, but Mum, she gave me life.”

“Fear makes companions of all of us.”

DOCTOR: He asked you a question. Will you help me?

CLARA: You shouldn't have been listening.

DOCTOR: I wasn't. I didn't need to. That was me talking. You can't see me, can you? You look at me, and you can't see me. Have you any idea what that's like? I'm not on the phone, I'm right here, standing in front of you. Please, just, just see me.

“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.”

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

“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?”

“Well, I am that mysterious adventurer in all of time and space, known only as Doctor Who. And these are my disposables, Exposition and Comic Relief.”

“There's this moment where you're sure you're about to die and then you're born. It's terrifying. Right now I'm a stranger to myself. There's echoes of who I was and a sort of call towards who I am. And I have to hold my nerve and trust all these new instincts. Shape myself towards them. I'll be fine. In the end. Hopefully. Well, I have to be, because you guys need help and if there's one thing I'm certain of, when people need help, I never refuse. Right? This is going to be fun.”

“We all change, when you think about it. We're all different people all through our lives. And that's okay, that's good, you've got to keep moving, so long as you remember all the people that you used to be. I will not forget one line of this. Not one day. I swear. I will always remember when the Doctor was me.”

BILL: So, the Time Lords, bit flexible on the whole man-woman thing, then, yeah?

DOCTOR: We're the most civilised civilisation in the universe. We're billions of years beyond your petty human obsession with gender and its associated stereotypes.

BILL: But you still call yourselves Time Lords?

DOCTOR: Yeah. Shut up.

“Without hope. Without witness. Without reward.”

DOCTOR: Relax, he's a fifty first century guy. He's just a bit more flexible when it comes to dancing.

ROSE: How flexible?

DOCTOR: Well, by his time, you lot have spread out across half the galaxy.

ROSE: Meaning?

DOCTOR: So many species, so little time.

ROSE: What, that's what we do when we get out there? That's our mission? We seek new life, and, and-

DOCTOR: Dance.

“If you could touch the alien sand and hear the cries of strange birds and watch them wheel in another sky, would that satisfy you?”

“Sometimes the only choices you have are bad ones. But you still have to choose.”

STRAX: There we go. Just a standard electro-cardio restart. She'll be fine.

VASTRA: Are you all right, my love? Can you hear me?

STRAX: The heart is a relatively simple thing.

VASTRA: I have not found it to be so.

DOCTOR: Hello, Sarah Jane.

SARAH JANE: [softly] It's you. Doctor. Oh, my God, it's you, isn't it? [realizing] You've regenerated.

DOCTOR: Oh. Half a dozen times since we last met.

SARAH JANE: You look.... incredible.

DOCTOR: So do you.

SARAH JANE: Hm. I got old. What are you doing here?

DOCTOR: Well. UFO sighting. School gets record results. I couldn't resist. What about you?

SARAH JANE: Same.

“Good evening. I'm a Lizard Woman from the Dawn of Time, and this is my wife.”

DOCTOR: Kate Lethbridge Stewart, a word to the wise. As I'm sure your father would have told you, I don't like being picked up.

CLARA: That probably sounded better in his head.

“They're not your rescuers. They're your replacements. The end point of capitalism. A bottom line where human life has no value at all. We're fighting an algorithm, a spreadsheet. Like every worker, everywhere, we're fighting the suits.”

“No broken bones. Slight loss of dignity. No change there then.”

“It's been good, though, hasn't it? All of us. All of it. Everything we did. (to Donna) You were brilliant. (to Jack) And you were brilliant. (to Rose) And you were brilliant. Blimey.”

JACK: Just my luck. I climb through two miles of ventilation shafts, chasing life signs on this thing, and who do I find? Mickey Mouse.

MICKEY: You can talk, Captain Cheesecake.

SARAH: So there's three of you?

ROSE: Three Doctors?

JACK: I can't tell you what I'm thinking right now.

DOCTOR: Tell me, Gwen Cooper, are you from an old Cardiff family?

GWEN: Yes, all the way back to the eighteen hundreds.

DOCTOR: Ah, thought so. Spatial genetic multiplicity.

ROSE: Oh, yeah.

DOCTOR: Yeah, it's a funny old world.

MR SMITH: I regret I will need remote access to TARDIS base code numerals.

DOCTOR: Oh, blimey, that's going to take a while.

SARAH: No, no, no. Let me. K9, out you come!

K9: Affirmative, Mistress.

DOCTOR: Oh! Oh ho! Oh, good dog!

“ (To Martha) You know, I'm not sure about UNIT these days. Maybe there's something else you could be doing?”

DONNA: Was it me, or was Isaac Newton hot?

DOCTOR: He was, wasn't he? He was so hot. Oh! Is that who I am now?

DONNA: Well, it was never that far from the surface, mate. I always thought…

“It's funny, cos I wonder where the TARDIS goes at random. Maybe it lands on some outcrop by the sea. And there's a tribe and they worship it for 100 years. Then they grow up and try to burn it. Then they get wise. They preserve it. Then they build a city all around it, till the TARDIS is just a tiny little dot, surrounded by skyscrapers and monorails. Time passes and the city falls. It all gets swept away. And there's the TARDIS… still on its outcrop… by the sea. She's the only thing I've got left.”

DOCTOR: Wilfred Mott. Oh, now I feel better. Now nothing is wrong, nothing in the whole wide world! Hello, me old soldier!

WILF: I never thought I'd see you again after all these years. Oh, Doctor, that lovely face! It's like springtime.

“My arms are too long.”

“I came to this universe with such delight. And I played them all, Doctor. I toyed with supernovas, turned galaxies into spinning tops. I gambled with God and made him a jack-in-the-box. I made a jigsaw out of your history. Did you like it? The Master was dying and begged for his life with one final game, and when he lost, I sealed him for all eternity inside my gold tooth. There's only one player I didn't dare face. The One Who Waits.”

DOCTOR: It's my back.

RIVER: Your back?

DOCTOR: Yeah, my back's playing up. It simply refuses to carry the weight of an entirely pointless stratum of society who contribute nothing of worth to the world and crush the hopes and dreams of working people.

DOCTOR: My entire understanding of physical space has been transformed! Three-dimensional Euclidean geometry has been torn up, thrown in the air and snogged to death! My grasp of the universal constants of physical reality has been changed forever!

DOCTOR: Sorry. I've always wanted to see that done properly.

DOCTOR: Times end, River, because they have to. Because there's no such thing as happy ever after. It's just a lie we tell ourselves because the truth is so hard.

RIVER: No, Doctor, you're wrong. Happy ever after doesn't mean forever. It just means time. A little time. But that's not the sort of thing you could ever understand, is it?

RORY: I have a message and a question. A message from the Doctor and a question from me. Where is my wife? Oh, don't give me those blank looks. The Twelfth Cyber Legion monitors this entire quadrant. You hear everything. So you tell me what I need to know. You tell me now, and I'll be on my way.

CYBERLEADER: What is the Doctor's message?

(Outside, all the other ships in the Legion explode.)

RORY: Would you like me to repeat the question?

RORY: I've come from the Doctor too.

RIVER: Yes, but at a different point in time.

RORY: Unless there's two of them.

RIVER: Now, that's a whole different birthday.

NIXON: You were my second choice for this, Mister Delaware.

CANTON: That's okay. You were my second choice for President, Mister Nixon.

AMY: Okay, why did you lie?

RIVER: Never let him see the damage. And never, ever let him see you age. He doesn't like endings.

“But you can't rewrite history! Not one line!”

KARVANISTA: You defile the sacred legacy of my forebears.

DAN: You don't look anything like four bears.

(Dan knocks out a Sontaran by hitting it in the back of the head with a wok)

DAN: How'd you like that, eh? Pan-fried Sontaran! Now I'm gonna... wok right out of here!

CLARA: What are you doing?

MISSY: Murdering a Dalek. I'm a Time Lady. It's our golf.

YASMIN: Make a wish and skim it.

DOCTOR: I wish...

YASMIN: You can't say your wish out loud!

DOCTOR: You can where I'm from. I wish... I wish this would go on forever.

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

RAM: What about football?

DOCTOR: Unbelievably boring sport. Now, darts? Darts is something worth practising for. Maths and alcoholic beverages. The best way to spend a morning.

“I'm being set up! Again! It's obvious. Why would I help you if I was the terrorist? I'm being set up, I tell you. Surely even you can see that. You can't let her stab me, K9, it's not legal!”
