Tasha Lem: Once, there was a planet much like any other. And unimportant. This planet sent the universe a message. A bell tolling among the stars, ringing out to all the dark corners of creation. And everybody came to see. Although no one understood the message, everyone who heard it found themselves afraid. Except one man. The man who stayed for Christmas.
Clara: Emergency. You're my boyfriend.
The Doctor: Ding dong, okay, brilliant. I may be a bit... rusty in some areas but I will glance at the manual.
Clara: No, no, you're not actually my boyfriend.
The Doctor: Oh, that was quick. It's a roller coaster, this phone call.
Clara: So I may have... accidentally invented a boyfriend.
The Doctor: Yeah, I did that once. And there's no easy way to get rid of an android.
Linda: How's the turkey doing?
Clara: Great, yeah, yeah, it's doing great. Well, dead and decapitated but that's Christmas when you're a turkey. Ha.
The Doctor: Okay, homing in on the mysterious message. Ooh, yes, I like that. "the mysterious message."
Clara: You shaved your head.
The Doctor: Yep. Clever plan to get us past the shield.
Clara: You got bored one night, didn't you?
The Doctor: Yeah, tiny bit bored.
The Doctor: And she's back. (kisses Tasha) Never could resist a row.
Tasha Lem: Kiss me when I ask.
The Doctor: Well, you'd better ask nicely.
Tasha Lem: In your dreams.
Clara: You can fly the TARDIS.
Tasha Lem: Flying the TARDIS was always easy. It was flying the Doctor I never quite mastered.
The Doctor: Are you Barnable?
Young Man: No, Doctor.
The Doctor: It's okay, Barnable, don't worry. I have got a plan. Off you pop. (once he leaves) I haven't got a plan. The people love it when I say that.
Clara: You've been asking the question, and it's time someone told you you've been getting it wrong. His name... his name is the Doctor. All the name he needs and everything you need to know about him. And if you love him, and you should, help him. Help him.
Dalek: The rules of regeneration are broken! You have expended all your lives!
The Doctor: Sorry? What did you say? Did you mention the rules? Now, listen. Bit of advice. Tell me the truth if you think you know it, lay down the law if you're feeling brave. But, Daleks, never ever tell me the rules!
The Doctor: Ooh, it just disappears, doesn't it? Everything you are, gone in a moment like breath on a mirror. Any moment now, he's a-comin'.
Clara: Who's coming?
The Doctor: The Doctor.
Clara: You... you are the Doctor.
The Doctor: Yep. And I always will be. But times change, and so must I.
The Doctor: We all change when you think about it. We're all different people, all through our lives. And that's okay, that's good, you got to keep moving so long as you remember all the people that you used to be. I will not forget one line of this, not one day. I swear. I will always remember when the Doctor was me.
The New Doctor: Kidneys! I’ve got new kidneys! I don't like the colour.
Clara: Of your kidneys? (the TARDIS shakes) What's happening?
The New Doctor: We're probably crashing! Oh!
Clara: Into what?
The New Doctor: Stay calm. Just one question. Do you happen to know how to fly this thing?
