I didn't always look like this. I'm on my tenth life. Well, tenth-and-a-half. There's another me running about, and I don't mean the one that Acumen put in my place, though that would be interesting. Wonder if Sentience would tell me if Acumen decided on a shortcut and put the human Doctor in my place. Part human, that is. Anyway, it's this thing I do. Regeneration. Nice little way to get around being dead permanently.
