"I expect you back by midnight." Dexter said teasingly to the Doctor as he went and began to speak with Liam asking to be told his story.
"My mother was from the Arctic Dessert, and my father was a Texan. I grew up down there as a girl. You know you could be flatter Dexter. Got a bit of a chin poking out."
"No thanks, rather be shot at by the universes worst nightmare than that. How many operations have you had?" He asked disgusted.
"Nine hundred and six. Next week it's going to be nine hundred and seven. Bleaching my blood. Is that why you wanted to have a little talk?" He asked. 
"You say you're the last human."
"The last [I]pure[/I] human. Others are half human, new humans, human-ish, or mixed in with some other aliens. Know what I call them? Mongrels."
"You're not really human at all. You had it nicked and tucked and taken all away and left behind a bitchy trampoline in it's wake. It's what humans do best, mix in with other's so that a new better person can be made. You just got left behind." Dexter shot. "I am more human than you are. My parents were both human too and born and raised on that planet." He said excusing himself from the...transgender-ed thing.
