"It's rather hard to explain unless you've seen it happen, but there's this process that Time Lords have in order to cheat death called regeneration. They completely change their cellular structure, appearance and all. I've seen two, not counting the one that I just told you about. As far as others... Well, there's a few. I haven't talked to many people, but I've seen plenty wandering around."
At the question of someone being in charge, Adric just smirked, "You expect someone to be in charge of chaos?" He asked before glancing over at Jack, studying his outfit. "Hrm. Military man. Guess you do expect someone to be in charge of chaos, then."
