what if Carver's really not the enemy? If he was he wouldn't even try to reason with Clem or the group. He would just kill them all on site. I think he just wants a group of survivors. He's like Roman who gives the group different jobs to do. Carver will try to reason with everyone, but Kenny will screw things up like he did with Larry. He will get Alvin or Sarita killed by trying to get revenge on Carver for killing Walter. It's Kenny's fault Walter died. If Kenny wouldn't had shot at Carver or Johnny Walter would still be alive.
Now what if the real enemy is Nate and he has his own group now? Nate isn't really a lone wolf because being alone makes him crazy. He would rather make friends to survive and do crazy things like steal people's stuff and talk crazy.
I know this may sound crazy but what if Luke's the real enemy? He seems much stranger than on episode 1. He thinks killing zombies is fun, I get a Psychological vibe form him. The way he reacts when he meets Kenny. He said he's good with women and children. He seems to know more about Carver than anyone else. Luke's plan seems to get everyone killed like Carver said. Could Luke be apart of the group that attacked Christa, and went to look for her since Clem told Luke and everyone about her? I doubt Kenny killed Luke because Kenny wouldn't kill someone unless their a walker or bitten. Yes Kenny got jealous, but doesn't mean he killed him.
Last thing to ask... Could Kenny be an antagonist in season 2? Kenny seems to be getting out of control; especially when he met Luke and accidentally called Clem Duck. Also when Walter died. Kenny is mentally scared which is causing him to go crazy. Him trying to get revenge on Carver will get himself and everyone killed except Clem. Carver see's Clem as trusting, tough, and different then the cabin group so he will try to reason with her....
