I could see them killing off Sam. He's probably got the least purpose out of the main characters. He's out of the running for Sookie's love, so bang goes that storyline. Same goes for Tara unless Eggs dies or something, and he doesn't have anything left to explore with his powers either. Shapeshifting would be useful if they did go down the scooby gang route, but otherwise he'll be left without much to do. I'd like to see him stay, though. It's nice to have a more down to Earth character that isn't willingly getting themselves into trouble all the time.
