DOCTOR: I mean, basically the code came from nowhere, but then so did the universe, and no-one complains about that.

MEL: Is this thing safe?

DOCTOR: Absolute deathtrap, Melanie B.

CHERRY: I've given up on that cuppa and opted for a life of abstinence.

DOCTOR: I know these teeth. What? What? What?!

He [The Doctor] thinks I take him where he wants to go. But. I'll let you into a secret, shall I?

I take him where he needs to be. Which is sometimes also where he wants to be. But not always.

London 1965, for instance. I could have got there in a second. If only he'd asked nicely. If only he hadn't been having fun. If only he hadn't been learning a lesson. About who he really needed to be, not who he wanted to be. But there we go – the old man had run away from his people intent on being a wanderer and never interfering. Instead those two schoolteachers taught him more about himself than he'd have learned in a thousand years of walking alone in eternity.

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

'My people constructed huge bowships that could fire massive stakes made of incorruptible metal through the enormous black hearts of these creatures. The mistake we made, because fundamentally my people are very lazy, was making these bowships intelligent.

'Intelligent?' repeated MacFarlane. 'Is that even possible?'

'Everything is possible in an infinite universe. But yes, artificial intelligence is a thing. Not necessarily a good thing, though as we found. Some of the bowships refused to cooperate, and some went rogue. Some unionized, and refused to attack any Great Vampires without adequate compensation and guarantees of survival. And some developed ways of dealing with the Great Vampires that we hadn't anticipated. That, I'm afraid, is what we're dealing with here.'

DOCTOR: It's always premature to declare victory. There's always someone or something to carry on the fight.

"He wished he could believe that the Doctor knew exactly what he was doing, but he was beginning to suspect that the fellow just did whatever occurred to him, whenever it happened to occur."

I knew that the Doctor would never really let me come to real harm. Although as we approached the very depths of Rotten Cobs, I couldn't help remembering all the terrible times when he had let really awful things happen to me. In Chroma, for instance. And Paris. And that moon with all the robots, and all kinds of places. It wasn't quite true that he was there to whisk me out of peril. Sometimes Mrs. Wibbsey has to come to her own rescue.

DOCTOR: Where were we? We need as much intel as we can get. If we're going to protect Rosa, we need to know the facts of her life. Home address, daily routine, where she works, the routes she takes, and the church she attends. Also, the name of the driver she refused.

GRAHAM: I know that. It's James Blake.

RYAN: How do you know that?

GRAHAM: Well, your Nan, when she found out I was a bus driver, said to me, you'd better not be like James Blake. Blake the snake, that's what she called him. And I had to ask her who he was and she just said he gave all bus drivers a bad name.

YASMIN: She said that when you'd only just met?

GRAHAM: Yeah.

'Then why bring me back here!' Caxton asked. His voice was desperate, pleading. 'Why bring me back here if I'm not supposed to stop it! Does someone hate me that much?'

'Time doesn't hate.' I said. 'It doesn't think, or feel, or care. Time is implacable, immovable, unchangeable, and eternal. It isn't cruel, or kind. It just is.'

(Add Thomas Caxton Tag?)

"I stood in the console room, my hands hovering over the door control. A part of me wanted to run, to go and find something wonderful and incredible and fun to see. To remind myself of the wonders of history, rather than the horrors. But the turbulence in the time vortex around the war had grown too great to ignore. 'Somebody has to do something about it.' I said to myself as I opened the doors. 'I can't keep putting it off forever'. So I stepped out of the TARDIS into the last days of the First World War."

[On the First Doctor]

"I soon found myself distracted by the Doctor. He was sat in a chair beside a large, blue box that looked very out of place in the trench. It had the words 'Police Public Call Box' written across the top above the doors. But neither the chair nor the box seemed as out of place as the man himself. His hair was white, his face lined with age. He was clearly too old for service, but there was something more to him than that. Somehow, he seemed to be the antithesis of the war itself, an incarnation of absolute peace, as forceful as the total war waging in the world around him.

There had been an ugly period when they [the Tenth and Eleventh Doctors] discovered a VHS tape of the movie Daleks: Invasion Earth and had insisted on watching it. They nearly derailed the negotiations by shouting, cheering, and joining in, and they had spent the next hour calling each other Dr. Who and talking like Peter Cushing.

DOCTOR: I offer you all the wisdom of the Lords of Time at your fingertips and all you want is better fishing.

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: I’m looking for my granddaughter. She attends this school…

SHIVANI: What’s her name?

DOCTOR: Susan.

SHIVANI: We have quite a few Susans. What year is she in?

DOCTOR: 1963, madam. The same as you and I and everybody...

SHIVANI: No. I meant… How old is she?

DOCTOR: Ah. She is 73 years old.

SHIVANI: Are you…

DOCTOR: Worried? Of course! She mustn’t try to walk home through that!

SHIVANI: You know, when I first met you… I thought you were strange. The way you answered my

questions. The way you look. I was a bit frightened of you.

DOCTOR: Ah. The curse of the immigrant.

SHIVANI: Me?

DOCTOR: Me.

DOCTOR: Without hope. Without witness. Without reward.

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?

DOCTOR: I’m the Doctor. Google me, I dare you. It’ll blow your mind. The only true bits are the ones that are impossible to believe.

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