DOCTOR: Oh, you should have seen it, that old planet. The second sun would rise in the south, and the mountains would shine. The leaves on the trees were silver, and when they caught the light every morning, it looked like a forest on fire. When the autumn came, the breeze would blow through the branches like a song.

DOCTOR: Everybody lives, Rose. Just this once, everybody lives!

DOCTOR: Amazing. 1941. Right now, not very far from here, the German war machine is rolling up the map of Europe. Country after country, falling like dominoes. Nothing can stop it. Nothing. Until one, tiny, damp little island says no. No. Not here. A mouse in front of a lion. You're amazing, the lot of you. Don't know what you do to Hitler, but you frighten the hell out of me. Off you go then do what you've got to do. Save the world.

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.
