I`m guessing arlene being bumped to supporting char is to setup her demon baby storyline. The baby can see dead spirits okay, we now know Lafyette can communicate with dead spirits. Oh the main antagonist a witch, Marnie can communicate with dead spirits. Vamps are going to need a medium who can help defeat the possessed witch call in Lafyette help take out Marnie, get rid of demon baby save vamps. Those are three stories that weave into one another. PosMarnie is going to try and make vampires walk in the sun sometime soon. Weave in Jessica Bill and all the rest of vamps everyone in the show is now involved. Except maybe Sam and Alcide. And those two will intertwine because Sam is dating that chick who`s ex was Alcide`s packmaster.
Oh this is all speculation by the way. In other words everyone chill out and watch and enjoy the fucking show.
