I really wanted to know. I don't know if this has been answered but I want to know, what was exactly wrong with Kenny? He didn't seem really crazy, he just looked happy to see Clem. Is he jealous of the new group? Does he have hallucinations about his family or Lee? What is it?
MOD EDIT: Mind the spoilers in thread titles please. Not everyone's had a chance to play Ep2 yet, and we don't want to ruin Kenny's return for them. Thanks!
