We mustn't change history,' Susan pouted. Ian had been so awed by her work on the portal, he'd almost forgotten she was just in her teens.'But Susan,' said the Doctor in his softest voice, 'we change history every time we step out of the door of the Ship.''You said that—' began Barbara.The Doctor whirled on her. 'Do you really want to know, Miss Wright?' he said. 'Do you really want to know? The TARDIS is built specifically not to change history. We can visit, we can observe, and the Ship can disguise itself so no one need ever know we were there. But only so long as we never step outside. We watch it all on the scanner. My people, you see...' He paused, searching for the words.'Doctor?' Barbara prompted.'I couldn't do that, could you?' he said. 'It's not travel, it wouldn't be real. We've seen the most incredible things, but without stepping out of those doors, I might as well have stayed in your time, content with your television sets.

When he pursed his lips and dropped a hand into his coat pocket, the last thing Nur expected him to pull out was a cricket ball. "I'd hoped for a disruptor at least," she muttered reprovingly. The Doctor slipped three fingers around the ball and hefted it experimentally. "I thought we'd try something a little less excessive." He breathed gently on to the maroon leather and polished it on his leg as the Sontaran finally tossed the Kshatriya aside and stopped to pick up its fallen weapon. He stepped around the corner, sighting along his free arm as the Sontaran straightened, its back fully turned. The cricket ball flashed down the length of the corridor in the blink of an eye, punching into the back of the Sontaran's collar and ricocheting away. To Nur's astonishment, the alien spasmed and crashed to the floor like a falling tree. "Out for a duck," the Doctor commented, blowing across his fingertips. "I've never seen anything killed by a cricket ball before." "You haven't yet. He'll wake up in a few minutes.

He took her by the hand and led her out of the control room and into a little side room. There, amid a lot of sculpting paraphernalia, was her statue. The statue from the museum. The statue of Fortuna. New and gleaming.Rose gaped. 'But I never posed for this.''No need,' said the Doctor, patting it on the arm -- an arm which still had a hand attached.'What d'you mean?''I mean,' he explained, 'that you won't have to pose for it. As Mickey said -' the Doctor smiled to himself - 'it was sculpted by someone who knew you pretty well.'He ran a hand through his hair and looked as though he was expecting applause.Rose walked round the statue. 'Is my bum really that--''Yes,' the Doctor interrupted testily. 'This statue is accurate in every detail. Bum. Arms. Legs. Nose. Broken fingernail on your right hand.'* * *Rose stood looking at the statue for a bit longer. 'It is perfect,' she said at last.'I was inspired.'They smiled at each other. All was right with the world again.

Rose Tyler: The time war ends. Emperor Dalek: I will not die! I cannot diieee! [we see Rose's eyes light up, and the Dalek Emperor and his entire fleet disappear in an explosion of golden dust] The Doctor: Rose, you've done it, now stop. [Rose stares straight ahead] The Doctor: Just let go. Rose Tyler: How can I let go of this? I bring life. [we see Jack start breathing again and open his eyes] The Doctor: But this is wrong! You can't control life and death! Rose Tyler: But I can. The sun and the moon, the day and night... but why do they hurt? [she is crying] The Doctor: The power's gonna kill you and it's my fault! Rose Tyler: I can see everything... all that is... all that was... all that ever could be. The Doctor: [stands up] But that's what *I* see. All the time. And doesn't it drive you mad? Rose Tyler: [Rose nods, barely able to speak] My head... The Doctor: Come here. Rose Tyler: ...is killing me. The Doctor: I think you need a Doctor. [He leans down and kisses her, and the golden light transfers from her to him through their lips]

The Doctor. He grabbed hold of Rory's ankle, dragging him protesting out from under the table. 'Rory!' he grinned, wrapping him in an enourmous bear hug that squeezed the breath out of him. 'I've been you!''Right,' mumbled Rory.'You've had a gorgeous time, I bet.''Not... especially, no.'The Doctor stepped back, his eyes were wide and dancing. 'Did you escape from any monsters? Did you set anything on fire? I'm always doing that. Honestly, one minute it's Tell Me Your Plans, the next it's BOOOM! My insurance premiums are terrible... Anyhow, you're all back to normal, yes?''Yes.' Rory was ever so tight-lipped.The Doctor nudged him with his elbow. 'Go on then. What was it like being me? Wasn't it just a bit brilliant? Did it open up your tiny mind?'Rory looked a little ill. 'It's nice to be me, actually. I'm not a hero... And what was it like being me?' he asked.The Doctor tugged at his braces, embarrassed. 'Oh, don't apologize - I'm sure I'll get over it.

He had on – oh wow, he was wearing that outfit again. The one he’d lost in the prison. ‘Hang about,’ Sam managed.‘How’d you get –’‘I made a little side trip,’ said the Doctor. ‘There’s a tailor in Neo Sydney who was more than happy to make these up for me.’ Now she was close enough to touch, she could see it wasn’t the same – every last detail of the design was right, but so much more care and workmanship had gone into this outfit than the original. She ran her hands over the fabric: that coat was real velvet, not costume shop velveteen, and the cravat had the softness of real silk. Instead of the hasty costume stitching, which frayed badly even under normal wear (much less Doctor wear), these seams were reinforced, built to last. These clothes were meant to be worn for real. She looked up at him, still grinning. Only he would get an expensive tailor to use authentic period materials to re create a fancy dress outfit. And all so it could be worn by a man who wasn’t from the same century, or even the same planet.

River Song: Use the stabilisers! The Doctor: It doesn't have stabilisers! River Song: The blue switches! The Doctor: The blue ones don't do anything, they're just... blue! River Song: Yes they're blue: they're the blue stabilisers! [presses the button and the TARDIS indeed stabilises] See? The Doctor: Yeah? Well, it's boring now, isn't it? They're boring-ers! They're blue... boring-ers! Amy: Doctor, how come she can fly the TARDIS? The Doctor: You call that flying the TARDIS? [scoffs] Ha! River Song: Okay, I've mapped the probability vectors, done a foldback on the temporal isometry, charted the ship to its destination and... [presses a button, the cloister bell clangs] parked us right alongside. The Doctor: Parked us? But we haven't landed! River Song: Of course we've landed; I just landed her. The Doctor: But it didn't make the noise. River Song: What noise? The Doctor: You know, the... [does an impression of the TARDIS materialisation sound] River Song: It's not supposed to make that noise. You leave the brakes on.The Doctor: Yes, well, it's a brilliant noise. I love that noise.

Creatures from another world, only statues when you see them. Lonely Assassins, that's what they used to be called. No one quite knows where they came from, but they're as old as the Universe, or very nearly. And they have survived this long because they have the most perfect defence system ever evolved. They are Quantum Locked. They don't exist when they are being observed. The moment they are seen by any other living creature they freeze into rock. No choice, it's a fact of their biology. In the sight of any living thing, they literally turn into stone. And you can't kill a stone. Of course, a stone can't kill you either, but then you turn your head away. Then you blink. Then, oh yes, it can. That's why they cover their eyes. They're not weeping, they can't risk looking at each other. Their greatest asset is their greatest curse. They can never be seen. Loneliest creatures in the Universe. And I'm sorry. I am very, very sorry. It's up to you now. Don't blink. Don't even blink. Blink and you're dead. They are fast. Faster than you can believe. Don't turn your back, don't look away, and DON'T blink. Good luck.

Donna to the policewoman: Don't you touch this car!The Doctor watching: She's not changed.Wilfred: Oh. There he is. Shawn Temple. They're engaged. Getting married in the Spring.The Doctor: Another wedding.Wilfred: Yeah.The Doctor: Hold on, she's not going to be called Noble-Temple. It sounds like a tourist spot.Wilfred: No it's Temple-Noble.The Doctor: Right. Is she happy? Is he nice?Wilfred: Yeah, he's sweet enough. He's a bit of a dreamer. Mind you he's on minimum wage. She's earning tuppence so all they can afford is a tiny little flat. And then sometimes I see this look on her face. Like she's so sad. And she can't remember why.The Doctor: She's got him.Wilfred: She's making do.The Doctor: Aren't we all.Wilfred: How 'bout you? Who've you got now?The Doctor: No one. Travelling alone. I thought it would be better. But I did some things, it went wrong. I need— {he starts to cry}Wilfred: Oh my word. I—The Doctor: Mm. Merry Christmas.Wilfred: Yeah. And you.The Doctor: Look at us.Wilfred: Don't you see? You need her, Doctor. I mean, look, wouldn't she make you laugh again? Good ol' Donna. -Doctor Who

The Doctor: [hologram, speaking towards the console] This is Emergency Programme One. Rose, now listen, this is important. If this message is activated, then it can only mean one thing: we must be in danger, and I mean fatal. I'm dead, or about to die any second with no chance of escape. Rose Tyler: No! The Doctor: And that's OK, I hope it's a good death. But I promised to look after you, and that's what I'm doin'. The TARDIS is takin' you home. Rose Tyler: I won't let you. The Doctor: And I bet you're fussing and moaning now, typical. But hold on, and just listen a bit more. The TARDIS can never return for me. Emergency Programme One means I'm facing an enemy that should never get their hooves on this machine. So this is what you should do: let the TARDIS die. Just let this old box gather dust. No one can open it, no one will even notice it. Let it become a strange little thing standing on a street corner. And over the years, the world will move on, and the box will be buried. And if you wanna remember me, then you can do one thing. That's all, one thing. The Doctor: [hologram turns to face Rose, and with a full voice] Have a good life. Do that for me, Rose. Have a fantastic life.

Okay then. That's what I'll do. I'll tell you a story. Can you hear them? All these people who lived in terror of you and your judgment. All these people whose ancestors devoted themselves, sacrificed themselves to you. Can you hear them singing? Oh you like to think you're a god. But you're not a god. You're just a parasite. Eaten with jealousy and envy and longing for the lives of others. You feed on them. On the memory of love and loss and birth and death and joy and sorrow, so... so come on then. Take mine. Take my memories. But I hope you're got a big a big appetite. Because I've lived a long life. And I've seen a few things. I walked away from the last great Time War. I marked the passing of the Time Lords. I saw the birth of the universe and watched as time ran out, moment by moment, until nothing remained. No time, no space. Just me! I walked in universes where the laws of physics were devised by the mind of a madman! And I watched universes freeze and creation burn! I have seen things you wouldn't believe! I have lost things you will never understand! And I know things, secrets that must never be told, knowledge that must never be spoken! Knowledge that will make parasite gods blaze! So come on then! Take it! Take it all, baby! Have it! You have it all!

Amy: Oh, typical bloke. Straight to fixing his motor.The Doctor: Well, that's the thing, Amy. I am not a typical bloke.Amy: Sorry, did I do something wrong? 'Cause I'm getting kind of mixed signals here!The Doctor: Mixed signals? How?Amy: Oh, come on. You turn up in the middle of the night, get me out of my bed in my nightie, which you then don't let me change out of for ages, and take me for a spin in your time machine? No, no, you're right, no mixed signals there. That is just a signal! Like a great, big Bat-signal in the sky. "Get your coat, love, the Doctor is in."The Doctor: ... No! No! Nonononononono, it's... not like that. That's not what I'm like!Amy: Then what are you like?The Doctor: I dunno, Gandalf. Like a space Gandalf. Or that little green guy in Star Wars... [spins around, making a lightsaber sound effect]Amy: [stifles a chuckle] You really are not. You. Are. A bloke.The Doctor: I'm the Doctor.Amy: Every room you walk into, you laugh at all the men and show off to all the girls.The Doctor: Do not.Amy: What about Rory? [the Doctor snort-laughs, gesturing toward his nose] You laughed!The Doctor: No, that was just an involuntary snort... of... fondness!Amy: You are a bloke and you don't know it. [puts her arms around him] And here I am to help.The Doctor: [pushing her away] That is not why you're here.Amy: Then why am I here?The Doctor: Because! [lowers his voice] Because I can't see it anymore.Amy: See what?The Doctor: I'm 907. After a while... you just can't see it!Amy: See what?The Doctor: Everything! I look at a star and it's just a big ball of burning gas and I know how it began and I know how it ends and I was probably there both times. After a while, everything is just stuff! That's the problem. You make all of space and time your backyard and what do you have? A backyard. But you, you can see it. And when you see it, I see it.Amy: And that's the only reason you took me with you?The Doctor: There are worse reasons.Amy: [snorts] I was certainly hoping so. [pause] Does that mean I'm not the first, then? There've been others travelling with you?The Doctor: [chuckles nervously] Yeah, sure. Loads of 'em, but just friends. You know, chums, pals, mates, buddies--not mates, forget mates.Amy: And out of all those friends, how many would you say, just out of curiosity, were girls?The Doctor: [getting increasingly uncomfortable] Oh... some of them, I suppose. Must have been.Amy: "Some?"The Doctor: It's hard to tell. It's a grey area.Amy: Under half, over half?The Doctor: Probably... slightly... a little bit over?Amy: Hmm. Young?The Doctor: Everyone's young, compared to me.Amy: [chuckles] Hot?The Doctor: No, no no no no no no, none of them. Not really. Not at all. Probably not... [scratches his cheek nervously] ... maybe one or two. I didn't really notice.Amy: Well, this big ol' machine must have some kind of visual records.The Doctor: Oh, god, I mean no--and anyway, they're voice-locked!Amy: [laughs] Oh, voice-locked. So I'd just have to say... "Show me all visual records of previous TARDIS inhabitants?"The Doctor: No, nonono, I mean voice-locked. I would have to say, "Show me all visual records of previous TARDIS inhabitants."Amy: Awww. Thank you.The Doctor: No, no! No! No![The TARDIS makes some noises as pictures of past female companions flip by on the viewscreen]Amy: Ha-ha! Ooh, Gandalf!The Doctor: [to the TARDIS] Thanks. Thanks, dear. Miss out the metal dog, why don't you?Amy: Is that a leather bikini? [pictures of Leela start to flip by]The Doctor: Right! That's it. Rory. We're going to find Rory, and we're gonna find him now!Amy: He's at his stag night.The Doctor: Well, then. Let's make it a great one.
