DOCTOR: Charley, C'Rizz, Lucie, Tamsin, Molly. Friends, companions I've known, I salute you. And Cass, I apologise. Physician, heal thyself.

DOCTOR: I'm a doctor. But probably not the one you're expecting.

DOCTOR: People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey... stuff.

DOCTOR: Everybody lives, Rose. Just this once, everybody lives!

DOCTOR: The Daleks have failed! Why don't you finish the job and make the Daleks extinct. Rid the Universe of your filth. Why don't you just die?

DALEK: You would make a good Dalek.

DOCTOR: You feel that pounding in your heart? That tightness in the pit of your stomach? The blood rushing to your head, do you know what that is? That's adventure. The thrill and the fear, and the joy of stepping into the unknown. That's why we're all here, and that's why we're alive!

PERI: I think you fainted.

DOCTOR: I never faint. I remember now. I felt a weakness. I felt a weakness and then I, I was in another place.

PERI: Can I get you anything? Celery! That's what you need.

DOCTOR: Celery, yes. And the tensile strength of jelly babies! But I, I had a clarinet. Or was it a flute? Something you blew into.

PERI: A glass of water?

DOCTOR: Water? No, don't think so. A recorder! That's what it was. Some kind of mind lock.

PERI: I only hope it believes you.

DOCTOR: Well, if it doesn't, I shall beat it into submission with my charm.

DOCTOR: Whatever else happens, I am the Doctor, whether you like it or not.

DOCTOR: The very powerful and the very stupid have one thing in common. They don’t alter their views to fit the facts, they alter the facts to fit their views. Which can be uncomfortable if you happen to be one of the facts that needs altering.

DOCTOR: But the final responsibility is mine, and mine alone. Listen, if someone who knew the future pointed out a child to you and told you that that child would grow up totally evil, to be a ruthless dictator who would destroy millions of lives, could you then kill that child?

SARAH JANE: Doctor, you're being childish.

DOCTOR: Well of course I am. There's no point in being grown up if you can't be childish sometimes.

DOCTOR: When you get back to Skaro, you’ll all be national heroes. Everybody’ll want to hear about your adventures. So be careful how you tell that story, will you? Don’t glamourize it. Don’t make war sound like an exciting and thrilling game. Tell them about the members of your mission that will not be returning. Like Maro, Vaber and Marat. Tell them about the fear. Otherwise your people might relish the idea of war. We don’t want that.

DOCTOR: You look very nice in that dress, Victoria.

VICTORIA: Thank you. Don't you think it's a bit--

DOCTOR: A bit short? Oh, I shouldn't worry about that. Look at Jamie's.
