I hope the mid-season finale plays out like this. I put in spoiler tags because of some references to the comics...
Rick and the group infiltrate Woodbury and somehow Rick happens upon Penny. He kills her as a callback to the first scene of the series, and this is what FINALLY pushes The Governor into visual bat**** crazy mode. Governor, or most likely Merle, will chop off Rick's hand, the Governor will rape Michonne, and Oscar will end up dead since Tyresse is joining the cast soon. Back at the prison, the inmate whose name I can't remember will do something bad to Beth. IDK why, but I can't shake the feeling that he's only there to perform a terrible act.
