Emperor Dalek: Explain yourself.
The Doctor: I said no.
Emperor Dalek: What is the meaning of this negative?
The Doctor: It means no!
Emperor Dalek: But she will be destroyed!
The Doctor: No! 'Cause this is what I'm gonna do - I'm gonna rescue her! I'm gonna save Rose Tyler from the middle of the Dalek fleet, and then I'm gonna save the Earth, and then - just to finish you off - I'm gonna wipe every last stinking Dalek out of the sky!
Emperor Dalek: But you have no weapons, no defences, no plan!
The Doctor: Yeah, and doesn't that scare you to death?
Sarah-Jane: I had no problem with space stuff. I saw things you wouldn't believe.
Rose: Try me.
Rose: I've met ghosts.
Sarah-Jane: Robots. Lots of robots.
Rose: Slitheen. In Downing Street.
Rose: Met the Emperor.
Sarah-Jane: Anti-Matter monsters.
Rose: Gas masked zombies.
Sarah-Jane: Real living dinosaurs!
Rose: Real living werewolf!
Sarah-Jane: The Loch Ness Monster!
[Mickey has his finger on a button on the console.]
The Doctor: Um... What're you doing that for?
Mickey: 'Cause you told me to.
The Doctor: When was that?
Mickey: About half an hour ago.
The Doctor: Um. You can let go now.
Mickey: Well, how long's it been since I could've stopped?
The Doctor: Ten minutes? Twenty? ... Twenty-nine?
Mickey: You just forgot me!
The Doctor: No, no, no! I was just...I was just...I was calibrating. I was just...no, I know exactly what I'm doing.
Rose: Will it... That thing... Is it trapped for good? On video?
Doctor: Hope so. Just to be on the safe side though, I'll use my unrivaled knowledge of trans temporal extirpation methods to neutralise the residual electronic pattern.
Rose: You what?
Doctor: I'm going to tape over it.
Doctor: Fear. Loneliness. They're the big ones, Rose. Some of the most terrible acts ever committed have been inspired by them. We're not dealing with something that wants to conquer or destroy. There's a lot of things you need to get across this universe. Warp drive... Wormhole refractors...You know the thing you need most of all? You need a hand to hold.
Rose: But, it's like...think about it, though. Christmas. 1860. Happens once. Just once, and it's gone. It's finished. It'll never happen again. Except for you. You can go back and see days that are dead and gone and a hundred thousand sunsets ago. No wonder you never stay still.
Rose: What's the emergency?
The Doctor: It's mauve.
The Doctor: The universally recognized colour for danger.
Rose: What happened to red?
The Doctor: That's just humans. By everyone else's standards, red's camp. Oh, the misunderstandings. All those red alerts, all that dancing.
