The Doctor and Nancy in “The Empty Child”

Amazing.

What is?

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. I don't know what you did to Hitler, but you frighten the hell out of me, go on, do what you've got to do, save the world.
