"Planet Earth. This is where I was born. And this is where I died. The first nineteen years of my life, nothing happened. Nothing at all, not ever. And then I met a man called the Doctor. A man who could change his face. And he took me away from home in his magical machine. He showed me the whole of time and space. I thought it would never end. … Well, that's what I thought. But then came the Army of Ghosts. Then came Torchwood and the war. That's when it all ended. This is the story of how I died."

"Five million Cybermen? Easy. One Doctor? Now you're scared!"

"I made my choice a long time ago, and I'm never gonna leave you."

"Right, now we're in trouble. And it's only just beginning..."

"Dalek [1.6] (30 April 2005)"

"You sent her home. She's safe."

"The Idiot's Lantern [2.7] (27 May 2006)"

"I've seen fake gods and bad gods and demigods and would-be gods; out of all that, out of that whole pantheon, if I believe in one thing... just one thing... I believe in her."

"The Shakespeare Code [3.2](7 April 2007)"

"She's just an invention. Rose, I call her. Rose. She seems to disappear later on."

"Oh, she was blonde! Oh, what a surprise!"

"I could go back in time and help Rose Tyler with her homework!"

"In the US remake of Broadchurch, Gracepoint, both of which star David Tennant, an enquiry sheet on his desk has the name R. Tyler written on it, enquiring about a wolf (a reference to Bad Wolf)."

"Rose was a girlfriend, really. I know we don’t say it."

"I travelled across the world. From the ruins of New York, to the fusion mills of China, right across the radiation pits of Europe. And everywhere I went I saw people just like you, living as slaves! But if Martha Jones became a legend then that's wrong, because my name isn't important. There's someone else. The man who sent me out there, the man who told me to walk the Earth. And his name is The Doctor. He has saved your lives so many times and you never even knew he was there. He never stops. He never stays. He never asks to be thanked. But I've seen him, I know him... I love him... And I know what he can do."

"I spent a lot of time with you thinking I was second best. But you know what? I am good."

"You need to be careful, because you know the Doctor's wonderful and he's brilliant, but he's like fire. Stand too close and people get burned."

"Suddenly, in an underground mortuary on a wet night in Cardiff, I hear the song of a nightingale!"

"That Martha must've done you good."

"Excellent bottom!"

"I've kind of made Jack a hero that I would like to have looked up to as a little boy because as a little boy, I knew I was gay but I didn't know what it was. Didn't know who to talk to about it. … I wanted kids to like him, and I wanted women, men, I wanted everyone to like him. But first I wanted people to hate him. I wanted them to think he was arrogant and pushy and too sure of himself. And I wanted them to follow the arc of the change he went through in the final episodes of Doctor Who."

"In terms of Jack's sexuality it was a really bold thing that Russell [T Davies] did putting him right in the middle of a show at seven o'clock. For young people to see a character who is such a positive role model, who is honest and decent and good and a hero, and for him to have a sort of non-defined sexuality I think it's a really important thing to see. Your sexuality doesn’t make you a good or bad person. And John was really keen on that too, he was really excited about the opportunity to do that I think."

"Captain Jack Harkness. I thought it was very refreshing to see such a lead character. He’s omnisexual and explores men, women, cupboards… You name it, he explored it."

"I could go on all Jack's stag parties in one night!"

"He likes to call himself Captain Jack, but I'm not buying it."

"I swear to you: If your duty is to protect the state above and beyond any other authority, then the one person you need right now is Jack Harkness."

"It's not... Men, it's...it's just him. It's only him."

"The problem seems to be an American with no sense of timing or fashion."

"Reset [2.6] (13 February 2008)"

"You always remember what you kill - Don't you, Jack?"

"...He is dashing, you have to give him that."

"Sleeper [2.2] (23 January 2008)"

"And the good thing is, he's not dead for long. I GET TO KILL HIM AGAIN!"

"Day One [1.2] (22 October 2006)"

"The Doctor Dances [1.10] (28 May 2005)"

"You have no idea what it felt like, coming back to life and knowing the world was empty...because you'd gone!"

"You've heard of immaculate conception, haven't you? Well..."

"If you've got forever, you don't notice the flecks in the concrete, or bother to touch the bricks... You send your friends into danger, knowing the stakes aren't the same for you, that you might get them killed - while you walk away unscathed."

"You need to figure out who's side you're on here, because if you don't know, you're not gonna make it out of this alive."

"You people and your quaint little categories."

"And before we go any further, who the hell orders pizza under the name of "Torchwood"?"

"There you go! I can taste it! Oestrogen. Definitely oestrogen. Take the pill, flush it away, it enters the water cycle. Feminizes the fish. Goes all the way up into the sky then falls all the way back down onto me. Contraceptives in the rain. Love this planet. Still, at least I won't get pregnant. Never doing that again."

"Sorry, old man! I gotta go meet a girl...But you've got an excellent bottom, too!"
