I am shocked to come on here and see nothing about last night's episode. Who does everyone think is the killer?
I didn't quite get the whole thing with Carol not wanting Rick to know that she was teaching the kids to defend themselves, and not wanting Carl to tell. Because the parents would find out? I would think the parents already realize what kind of world they live in, and would understand. If not, too bad.
Unless, part of me thinks this whole thing was being played up because Lizzie and Myca . . . were they the ones feeding the walkers at the fence? Are they the ones who killed Karen and David? It seems unbelievable, but the reason I am thinking that is because when they were at the fence and Carol said, "You're weak", Myca said, "No, she's just messed up"... so I could see them feeding "Nick" and the others at the fence, not thinking of them as the enemy. But then after being called weak, I could see Lizzie thinking that "These infected people killed my dad" and then thinking, "Hey Carol, I can use a knife just like you showed me" making Carol feel guilty for doing such a thing.
The only other person I thought could be the killer would be Bob the alkie, but he really wasn't very visible in this show. Though he does seem a little shady.
Oh, also... Caleb, the doctor.
David and Karen were infected first; they were the ones, at the beginning of the first episode, killing walkers at the fence. So now that most of the "main" characters were at the fence, are they all going to get infected too?
