Come on, Rory! It isn't rocket science, it's just quantum physics! -The Doctor (Matt Smith)

We're thrilled to have Maisie Williams joining us on Doctor Who. It's not possible to say too much about who or what she's playing, but she is going to challenge the Doctor in very unexpected ways. This time he might just be out of his depth, and we know Maisie is going to give him exactly the right sort of hell.

Everybody knows that everybody dies. But not every day. Not today. Some days are special. Some days are so, so blessed. Some days, nobody dies at all. Now and then, every once in a very long while, every day in a million days, when the wind stands fair and the Doctor comes to call, everybody lives.

Amy: "Can I come?" Doctor: "Not safe in here, not yet. Five minutes. Give me five minutes and I'll be right back." Amy: "People always say that." Doctor: "Am I people?...Do I even look like people?...Trust me, I'm the Doctor.

Amy: I never knew you drank wine. Doctor: I'm 1103 I must have drunk it sometime in my life. *takes sip and spits it out in disgust*

Rose: 'If you are an alien, how come you sound like you're from the north?' Doctor: 'Lots of planets have a north!

[The Doctor, Capt. Jack and Rose are cornered by the empty children.] The Doctor: Go to your room! Go to your room! I mean it. I'm very, very angry with you. I'm very, very cross! GO! TO! YOUR! ROOM! [The children lurch away and obey him.] I'm really glad that worked. Those would have been terrible last words.

The Doctor: It's my nose; it has special powers. Nancy: Yeah? That why it's so...? The Doctor: What? Nancy: Nothing. The Doctor: What? Nancy: Nothing. Do your ears have special powers too?

Rose: Look at you, beaming away like you're Father Christmas! The Doctor: Who says I'm not, red-bicycle-when-you-were-twelve? Rose: [shocked] What? The Doctor: And everybody lives, Rose! Everybody lives! I need more days like this! Go on, ask me anything; I'm on fire!
