Kevin Callinan
Kevin is a perfectly normal human being despite persistent rumors to the contrary. Pretty much anything you've heard about lizard people, human skin suits, a raisin-sized heart with just one remaining wisp of soul in it, etc. etc. can be dismissed as the blatant propaganda it is. There is a dog and a cat and a wife somewhere in California that will back him up with a quick and believable alibi should he need yet another.
