I'm the Doctor.. er.. well, the Doctor from parallel Universe. Parallel to the one we know of anyways. Still in my 10th incarnation, I slipped through from the other Earth when the Doctor was closing the void and lost Rose. I saw myself, pressed against the wall inside the Torchwood institute. I left, with fear of messing up time on a major scale. I was stuck in this Universe, since this version of me had closed the exit. I out lived this Doctor, he fought the master and regenerated into an 11th carnation, with a booming chin & a bow tie fetish.. but even thought Doctor has regenerated. I'm old, I'm 1,247 and still striding around in my tenth body, keeping weary of the other Doctor in this Universe.
