MARCO POLO: I saw again the years and years we spent on the road, in the trackless wastes, in the forests and jungles, in the shining deserts. Always heading on, and on. Always knowing we had to keep moving, and never looking back. Like we thought we’d never run out of world. And like we’d never run out of years.

DOCTOR: You always were a terrible judge of character. Look at me!

BERNICE: Happily.

DOCTOR: Have you had a good life?

BERNICE: All things considered.

DOCTOR: Quite. And you’ve just saved the universe again.

BERNICE: I have, haven’t I? Something to tell the cats when I get home.

DOCTOR: Cats, eh? Plural?

BERNICE: Plural.

DOCTOR: How many? Not too many?

BERNICE: No such thing. Oh, you’re going to love them. Come on.

DOCTOR: Back home?

BERNICE: And beyond.

DOCTOR: The mediator between the head and the hands must be the heart. If only.

DOCTOR: Who I am is where I stand. Where I stand is where I fall.

DOCTOR: Time And Relative Dimension In Space. TARDIS for short. You're safe in here. You're safe in here and you always will be.

IRIS WILDTHYME: Stories, hidden inside stories! Ooh, I love all that. Makes me feel right at home.

LEELA: She is quicksilver. I prefer steel.

DOCTOR: Do you know Puff the Magic Dragon?

BERNICE: We went out a few times. He was very immature.

DOCTOR: Do you know the bit where Jackie Paper leaves him? Leaves him all alone?

BERNICE: I really don’t want to hear this.

DOCTOR: The dragon can’t be brave without the little boy. He doesn’t have anything to be brave for. He might as well go, might as well drift off into myth, and just be something in old stories.

BERNICE: But what would happen then? There are other monsters, other terrible things out there beside the Hoothi.

DOCTOR: Many of them. Yes.

BERNICE: Well, they must be fought. Because—and this is important. You can’t just be alone. That’s a childish thing to be. You can’t just isolate yourself from everything, no matter what terrible things have happened. You have to help other people.

DOCTOR: That’s what Jackie Paper would have said.

BERNICE: Oh. Oh, I see.

DOCTOR: What do you think?

NOBODY NO-ONE: I’m going to kill everything! Everything that crawls, grows, wiggles and swims in all of reality. Bang! The whole lot! Finished! Kaput! Finito-complete-o! Gone! How’s that for a plan?

DOCTOR: Evelyn. Evelyn, can you hear me?

EVELYN: Oh, it’s you. I thought you might be my Doctor.

DOCTOR: You know me, never knowingly punctual.

EVELYN: You’re not surprised, are you? How did you know?

DOCTOR: Remember that calendar you had in the TARDIS, with all your old friends' birthdays written on it? Let’s just say I have something like that.

DOCTOR: Lucie, there's a lot of darkness out there. Some of it where Orbis used to be. But you know something? We wouldn't notice any of it if it weren't for all those little pinpricks of light; planets and stars. And that's where I go whenever I feel sad. The next bit of light in the darkness. Keep on moving. Never look back. Well, hardly ever.

NYSSA: He took my hands and he kissed my forehead. Then he started to walk forward towards the white figure. He turned back once and looked around, and somehow he found where all of us were looking at him.

DOCTOR: Thank you, all of you. Goodbye.

NYSSA: He said. And then he started to run with determination, without a hint of reluctance, because he still had things to do. He had someone to save back in the real world. He had a whole other self that he had to be to do that. He ran right into the white figure of the Watcher and he fell, fell into the figure, spiralling down until he was lost in the distance. I suppose if I never meet him again and grow old myself, I'll have to say that was the last time I saw him, in a dream. But without evidence, I'll say to people that I know he's still alive, somewhere out there. I'll know he's still travelling. I'll know that he's still having adventures. I'll know he always will be.

LEELA: I was so alone in the world of dreams when you left… The wildlands were dark and so quiet. I… I do not wish to be alone.

ROMANA: There will be a place for you with me. For always. Whatever face I wear.

DOCTOR: Tears from the depth of some divine despair rise in the heart and gather to the eyes, in looking on the happy autumn fields, and thinking of the days that are no more. I don't just switch my emotions on and off, Evelyn. It may look as though I do, but I don't. It's not a conscious thing. I can't help the way I am. Perhaps in my next regeneration I'll be different. Perhaps I'll take everything to heart, although, having met me, I'd say that was unlikely. A small type with an odd accent. Not looking forward to that at all.

EVELYN: I'm not asking you to change, Doctor, and I don't actually want you to change. I like you. I want to put all this behind us now. Now that we understand one another better.

DOCTOR: What about you? Will you miss Rossiter?

EVELYN: Mmm hmm. I will. A great deal. He calmed me down, made me see the value in not concentrating on the less important things.

DOCTOR: It's a challenge for me in some ways to travel with you, you know, Evelyn. I mean, I'm so terribly, terribly fond of all my companions. Each of them has been special to me, unique. It's not just anyone I let into the TARDIS.

EVELYN: And it's not just anyone who could put up with your mood swings.

DOCTOR: Indeed, indeed. But they've all been, well, I suppose I have to say younger.

EVELYN: Thank you.

DOCTOR: No, no, no, no. Perhaps I mean less experienced. Less well-rounded. I've travelled with my intellectual equals, with my emotional betters, but no one other than you, Evelyn, has been. Well, I've travelled with an American for some time recently, and I'm sure she would have told me the phrase I was looking for, however much it irks me to utter it. It was the whole kit and caboodle.

(Evelyn laughs.)

DOCTOR: Come here, Doctor Smythe. I think we both need a cuddle.

CHARLEY: Come on. Take my hand.

DOCTOR: But we can see now. We don’t need to hold on to each other.

CHARLEY: I know. Take my hand anyway.

MICKEY: The audio medium. It can be so deceptive…

DOCTOR: Love. Huh! Wrote a treatise on the chromosomal origins of love once, when I was a small boy. Proved categorically which gene began it, which enzymes carried it, which electrochemical receptors translated it… Took all the fun out of it. Got a rubbish grade, too. My tutor told me I’d missed the point.

GILBROOK: My great-grandfather was just a kid, working in the fields when it happened.

BRODLIK: When what happened?

GILBROOK: Fields. Can you imagine that? Huge areas of land where crops would grow. Crops that could feed dozens of people. And my great-granddad. He looked up into the sky. And so he told his son, and so he told my dad. He saw that Koteem ship explode. He saw it… He said it was like paint spilling across a table. It seemed that fast… He said.. He said it was almost beautiful.

DOCTOR: As for making a difference, I don’t think we really influenced anything at all.

DOCTOR: Sometimes, if you stare at a painting for too long and get too close to it, all you can see are the brushstrokes. The harder you stare, the more formless and meaningless it seems to become.

NYSSA: And that’s your analogy for the whole of the universe, is it? A painting you don’t want to look at too closely in case it doesn’t mean anything?

DOCTOR: I don’t know. Sometimes I think of it that way, yes.

DOCTOR: I'm a Time Lord. I can't change things, but I have one thing that no one else has, and that's the gift of Time. I gave that to Evelyn, so that she could give it to you. An extra night. Get through the night, they say. Things are darkest just before the dawn.

DOCTOR: Break, damn you! Break! You've never had a spanner like this thrown in you! Chew on me till your teeth crack. Grind me up till your gears lock. I'm the nail in your tyre, the potato jammed in your exhaust pipe, the treacle poured in your petrol tank. I'm the banana peel beneath your foot, the joker that ruins your straight flush, the coin that always comes up heads and the gun you didn't know was loaded. I am the Doctor!

DOCTOR : Injustice is the rule, but I want justice. Suffering is the rule, but I want to end it. Despair accords with reality, but I insist on hope. I don't accept it because it is unacceptable. I say no.

FITZ: I’ve been engineered to love you, Carmodi. With the Doctor... it’s the real thing.
