I am thinking maybe carol killed Karen and Decatur David (we hardly knew ya). It's just a guess because she's so hyper aggressive at the moment. Putting Daryl and Tyrese against one another would be an interesting story dynamic too... Like Daryl all you want, but he's a dude riding a Harley with SS runes on the tank.
I lean towards the patsy angle, but it tears up Carol inside... I was talking about this tonight with my mother (she's a huge fan, which is kinda funny. She likes dissecting everything about an episode as much as we do but computers scare her, so she won't be joining in).
She doesn't agree, but I think Rick blames a dead sick person who croaked while they were out getting meds... Rick says, "Yeah, 'Decatur Bob' told us right before he died... case closed!", and everything's relatively hunky dory except Carol's a bad liar. Might come to a head at some point, but IF there's not patsy angle, I'd say Carol's dead and Tyrese's time with the group is near its own end because I can't see Daryl going away or letting Tyrese go batty on Carol.
Carol's still a ***** btw... For all her hard speak, and all the Carol gushing on Talking Dead, she still got her machete stuck in a zombies head and fell down. Chicks, I tell ya.
Speaking of Talking Dead...
So, yeah, Kevin Smith officially usurped as the biggest *******/most annoying guest they have... Marilyn Manson now wears the tiara. I think the other two guests didn't get to speak nearly enough, despite both sounding like they had much better things to say. And Manson was largely incoherent and droned on in failed attempts to sound like he was thinking deep about every aspect of the show. He was horrible, and given Hardwick's treatment of him at times, I don't think he'll be back any time soon. Twiggy should come on though.
