ROSE: I think what the Doctor's trying to say is you may cut in.

(Rose extends her hand out to Jack to dance.)

DOCTOR: Rose! I've just remembered!

ROSE: What?

(The music changes from waltz to swing - Glenn Miller's In The Mood. The Doctor starts to click his fingers to the music and dance toward Rose and Jack.)

DOCTOR: I can dance! I can dance!

ROSE: Actually, Doctor, I thought Jack might like this dance.

DOCTOR: I'm sure he would, Rose. I'm absolutely certain. But who with?

(Rose chuckles and takes the Doctor's hand. They dance around the TARDIS while Jack watches.)

DOCTOR: The nanogenes will clean up the mess and switch themselves off, because I just told them to. Nancy and Jamie will go to Doctor Constantine for help, ditto. All in all, all things considered, fantastic!

ROSE: Look at you, beaming away like you're Father Christmas.

DOCTOR: Who says I'm not, red bicycle when you were twelve?

ROSE: What?

DOCTOR: Relax, he's a fifty first century guy. He's just a bit more flexible when it comes to dancing.

ROSE: How flexible?

DOCTOR: Well, by his time, you lot have spread out across half the galaxy.

ROSE: Meaning?

DOCTOR: So many species, so little time.

ROSE: What, that's what we do when we get out there? That's our mission? We seek new life, and, and-

DOCTOR: Dance.

DOCTOR: The Daleks have failed! Why don't you finish the job and make the Daleks extinct. Rid the Universe of your filth. Why don't you just die?

DALEK: You would make a good Dalek.

DOCTOR: Your race is dead! You all burnt, all of you. Ten million ships on fire. The entire Dalek race wiped out in one second.

DALEK: You lie!

DOCTOR: I watched it happen. I made it happen.

DOCTOR: You think it'll last forever, people and cars and concrete, but it won't. One day it's all gone. Even the sky. My planet's gone. It's dead. It burned like the Earth. It's just rocks and dust before its time.

ROSE: What happened?

DOCTOR: There was a war and we lost.

ROSE: A war with who? What about your people?

DOCTOR: I'm a Time Lord. I'm the last of the Time Lords. They're all gone. I'm the only survivor. I'm left travelling on my own 'cos there's no one else.

ROSE: There's me.

ROSE: You think you're so impressive.

DOCTOR: I am so impressive.

ROSE: You wish.

DOCTOR: That won't last, he's gay and she's an alien.

DOCTOR: Do you know like we were saying about the Earth revolving? It's like when you were a kid. The first time they tell you the world's turning and you just can't quite believe it because everything looks like it's standing still. I can feel it. The turn of the Earth. The ground beneath our feet is spinning at a thousand miles an hour, and the entire planet is hurtling round the sun at sixty seven thousand miles an hour, and I can feel it. We're falling through space, you and me, clinging to the skin of this tiny little world, and if we let go. That's who I am. Now, forget me, Rose Tyler. Go home.

DOCTOR: I'm the Doctor, by the way. What's your name?

ROSE: Rose.

DOCTOR: Nice to meet you, Rose. Run for your life!
