DOCTOR: I'm the winner. That's who I am. The Time Lord Victorious!

DOCTOR: There are laws of time. Once upon a time there were people in charge of those laws, but they died. They all died. Do you know who that leaves? Me! It's taken me all these years to realize that the laws of time are mine and they will obey me!

DOCTOR: Imagine it, Adelaide, if you began a journey that takes the human race all the way out to the stars. It begins with you, and then your granddaughter, you inspire her, so that in thirty years Susie Fontana Brooke is the pilot of the first lightspeed ship to Proxima Centauri. And then everywhere, with her children, and her children's children forging the way. To the Dragon Star, the Celestial Belt of the Winter Queen, the Map of the Watersnake Wormholes. One day a Brooke will even fall in love with a Tandonian prince, that's the start of a whole new species. But everything starts with you, Adelaide. From fifty years ago to right here, today. Imagine.

ADELAIDE: Who are you? Why are you telling me this? Doctor, why tell me?

DOCTOR: As consolation.

DOCTOR: ...in doing so, you make it happen. Anything I do just makes it happen.
