Caliban's talk about him overshadowing humanity, is similar to basements dudes claim that the "night" is gonna rule over. It is an interesting parallel that you have physical monsters: Caliban, basement dude and werewolf and the monsters that are hidden behind human niceties and clothes: Vanessa, Dorian, Victor Sir Malcolm and betting gang. I love that Victor was almost frothing at the mouth to do experiments on basement dude. At least the first own what they are.
I almost feel that Josh Hartness character despite all his flaws, is probably the most moral character on the show. At least he is willing to check the others, when they start doing crazy stuff. I still love Caliban and would his immortal bride if I could.
