Son: There's no such person as Father Christmas!
The Doctor: Oh yeah? whips out a photo Me and Father Christmas, Frank Sinatra's hunting lodge. 1952. See him in the back with the blonde. Albert Einstein, the three of us together. Vroom! Watch out! Okay? Keep the faith. Stay off the naughty list. Oo! Now what's this, then? I love this. Big flashy lighty thing. That's what brought me here. Big flashy lighty things have got me written all over them. Not actually. Give me time and a crayon. Now! This big flashy lighty thing is connected to the spire on your dome, yeah? And it controls the sky. Well, technically it controls the clouds. Which technically aren't clouds at all. Well they're clouds of tiny particles of ice. Ice clouds. Love that. Who's she?
Sardick: Nobody important.
The Doctor: "Nobody important". Blimey, that's amazing. D'you know, in 900 years of time and space I've never met anyone who wasn't important before.
