Steven wrote to me today, saying, 'Don't you feel like sticking your head out of the window and yelling, "I DON'T KNOW WHAT I'M DOING!!!"' Yes, absolutely. Solidarity. Fear is always the same. Different worries with different scripts, but the same baseline fear.

Rose:i love you Doctor:Quite right, and i guess if it's my last chance to say it... Rose Tyler... (the doctor fades, him in his TARDIS, with tear tracks and a tear running down his cheek)

Doctor Who: You want weapons? We're in a library. Books are the best weapon in the world. This room's the greatest arsenal we could have. Arm yourself! (from Tooth and Claw in Season 2)

The Doctor: Rose... before I go, I just want to tell you: you were fantastic. Absolutely fantastic. And do you know what? [Pause] So was I!

Harriet Jones: Did you notice when they fart, if you'll pardon the word, it doesn't just smell like a fart, if you'll pardon the word, it's something else. What is it? It's more like, um... Rose Tyler: Bad breath. Harriet Jones: That's it! The Doctor: Calcium decay. Now that Narrows it down!.. Calcium phosphate. Organic calcium. Living calcium. Creatures made out of living calcium. What else - what else? Hyphenated surnames. Yes! That narrows it down to one planet! Raxacoricofallapatorius! Mickey Smith: [sarcastically] Oh yeah, great! We can write 'em a letter.

There's nothing better than a party that turns into a death trap.
