There’s this emperor, and he asks this shepherd’s boy, “How many seconds in eternity?” And the shepherd’s boy says, “There’s this mountain of pure diamond. It takes an hour to climb it, and an hour to go around it. Every hundred years, a little bird comes and sharpens its beak on the diamond mountain. And when the entire mountain is chiselled away, the first second of eternity will have passed.”
So I’m basically pretending that the Meta-crisis copy of The Doctor that goes to live in an alternate universe with Rose, actually turned a bit evil… Master-like if you will. And assumes an alternative persona as Kilgrave..
