Some people might suspect sam, and some people might suspect Rene. But i really like Rene so i am not gonna go with him, everything tells me that it isnt him. Its not Rene because for one Rene left his fiances kids with sookie and bill, and said that everything would be fine so he trusts bill and knows he wont do anything. And i think that the only reason that he went to jail is because everyone had automatically suspected him for killing his own sister. Just like the police always suspect Jason for killing every girl even though we know its not him. So since they suspected him right off the bat they arrested him there for when he got out he wanted to probably start a new life with a different name and hair style.
Jason had told both Rene and that one dude (who can never find a date at all because hes to "shy") that Amy likes to do "V" So everyone is going to suspect Rene because he knows, and because his file came back in a bad way, and thats definately what the directors want you to think too. But i suspect the other guy. The other guy is just to quite, he never gets any girls at all. But he always tries. And at one point he had asked Sookie if she would like to dance with him but Sookie said no, but she thought he was a really nice guy and he ended up saying "Well thats because you really dont know me." He seems like a pretty solid, cool dude. But i just think that he cant take the fact that every girl he basically knows is either taken by a human or with a vampire. This is only my opinion though. But i am going to stick with it.
P.s. Some people still want to know why Sam had rolled around in that one girls bed with the latex gloves on, i dont know if this is the right answer or not but once again its just my opinion i think it was really because of his dog instincts. He had a picture with both him and her in his office and i think that he kind of had a thing for her, and liked her, liked her scent too. So rolling around in the bed was his way of sniffing her, remembering how she smelt. And since hes rolling, for those of you who have dogs, i bet you catch your dog rolling around all the time in either the grass or the rug just enjoying themselves.
