“Rose: My mum's here.
The Doctor: Oh, that's just what I need! Don't you dare make this place domestic!
Mickey Smith: You ruined my life, Doctor. [the Doctor turns and looks at him, irritated] They thought she was dead, I was a murder suspect because of you!
The Doctor: [looks at Rose] See what I mean? Domestic!
Mickey: I bet you don't even remember my name!
The Doctor: Ricky.
Mickey: It's Mickey!
The Doctor: No, it's Ricky.
Mickey: I think I know my own name!
The Doctor: You think you know your own name? How stupid are you?”

“He's like fire and ice and rage. He's like the night, and the storm in the heart of the sun. He's ancient and forever. He burns at the center of time and he can see the turn of the universe. And... he's wonderful. - Tim Latimer”

“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!”

“When you run with the Doctor, it feels like it'll never end. But however hard you try you can't run forever. Everybody knows that everybody dies and nobody knows it like the Doctor. But I do think that all the skies of all the worlds might just turn dark if he ever for one moment, accepts it. 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. (In the library, the Doctor walks back to the TARDIS. He stops, looking at the doors. Then he raises his hand, and stands there poised like that for a long moment. Finally he snaps his fingers. The doors open. He smiles slowly and walks in, joining Donna. Then he snaps his fingers again, and the doors close. River's voice continues over this.) 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.”
