Donna: But it’s better than that though! Don’t you see what he’s trying to give you. Tell her, go on.
Human Doctor: I look like him, I think like him. Same memories, same thoughts, same everything. Except, i’ve only got one heart.
Rose: Which means?
Human Doctor: I’m part human. Specifically the aging part. I’ll grow old and never regenerate. I’ve only got one life, Rose Tyler. I could spend it with you. If you want.
Rose: You’ll grow old at the same time as me?
Human doctor: Together.
Rose Tyler, defender of the Earth.
Rose: Queen Victoria is a werewolf?
Doctor: Could be. And her family had the Royal disease. Maybe she gave them a quick nip.
Rose: So, the Royal Family are werewolves?
Doctor: Well, maybe not yet. I mean, a single wolf cell could take a hundred years to mature. Might be ready by, ooh.. early 21st century?
Rose: Nah, that’s just ridiculous! Mind you. Princess Anne..
Doctor: I’ll say no more!
Rose: And if you think about it, they’re very private. They plan everything in advance. They could schedule themselves around the moon, we’d never know! They like hunting! They love blood sports! Oh my God, they’re werewolves!
