DOCTOR: You know when grown-ups tell you everything's going to be fine and you think they're probably lying to make you feel better?

AMELIA: Yes.

DOCTOR: Everything's going to be fine.

AMY: I'm fine. It's just, there's a whole world in here, just like you said. It's all true. I thought. Well, I started to think that maybe you were just like a madman with a box.

DOCTOR: Amy Pond, there's something you'd better understand about me, because it's important, and one day your life may depend on it. I am definitely a madman with a box.

DOCTOR: Mels. Short for-

MELS: Melody.

AMY: Yeah. I named my daughter after her.

DOCTOR: You named your daughter after your daughter.

DOCTOR: Honestly, Charles... Can I call you Charles? I'm such a big fan!

CHARLES DICKENS: Uh, you're a what? A big what?

DOCTOR: Fan! Number one fan, that's me!

CHARLES DICKENS: How exactly are you a "fan"? In what way do you resemble a means of keeping oneself cool?
