GWEN: What's the most beautiful thing you've ever seen? Not just on Earth.

JACK: I'm not doing this. I'm not giving final speeches.

GWEN: Just tell me. Anywhere in the Universe.

JACK: …I saw a firebird once. A tiny little thing, even smaller than a hummingbird. Literally made of fire. It only lives for a minute. It blazes different colours and sings. It gets so bright you have to close your eyes. And when you open them, it's gone. But the image stays behind your eyelids for longer than it was alive.
