“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: Who's she?

SARDICK: Nobody important.

DOCTOR: Nobody important. Blimey, that's amazing. Do you know, in nine hundred years of time and space, I've never met anyone who wasn't important before.

CLARA: Doctor, you are not the only person who ever lost someone. It's the story of everybody. Get over it. Beat it. Break free. 

(Her hand touches his cheek.)

CLARA: Doctor, it's time. Get up, off your arse, and win!

“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.”

“Everybody lives, Rose. Just this once, everybody lives!”

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

“You can tell the President, and please use these exact words, he's not my boss, and he's certainly not turning this into a war.”

“The best thing that you can do is to change gender again.”

“Meep meep!”

DOCTOR: Cheer up. Look, there's a mouse.

CHARLEY: I am deeply cheered.

“...”

“There's this emperor and he asks this shepherd's boy, how many seconds in eternity? And the shepherd's boy says there's this mountain of pure diamond. It takes an hour to climb it, and an hour to go around it! Every hundred years, a little bird comes and sharpens its beak on the diamond mountain. And when the entire mountain is chiselled away, the first second of eternity will have passed! You must think that's a hell of a long time. Personally, I think that's a hell of a bird.”

BUCKINGHAM: You would dare to take on one of the finest swordsmen in England?

DOCTOR: Hasn't anybody told you? We're in France!

CYBERMAN: Love is not a mission. Love is an emotion. Emotions are not missions.

BEL: And that's why you're dead on floor, and I put you there. (shoots it again) Love is the only mission. Idiot.

HARCOURT: Doctor Constantine.

CONSTANTINE: Mrs Harcourt. How much better you're looking.

HARCOURT: My leg's grown back. When I come to the hospital, I had one leg.

CONSTANTINE: Well, there is a war on. Is it possible you miscounted?

DOCTOR: You know, my dear, there's something very satisfying about destroying something that's evil, don't you think?

DODO: (enthusiastically) YES!

“I died fifteen years ago. Saw it in the times. "Professor Edward Travers, CBE. Silly old fool. No flowers, by request." But they still sent them. No one listens.”
