The news about a major The Walking Dead actor potentially leaving the show to join Frank Darabont on his new TNT show, L.A. Noir, might be a bit surprising to some, considering that the actor's character is still alive and well on The Walking Dead. As such, a few sites, including the AV Club, have made the assumption that that must mean that said actor's character will be killed off in the latter half of the coming season.
True? Maybe. Said actor may be weighing his options on whether or not he'd like to return to the show, and may or may not be under contract after this season. Or, indeed, he might be about to get killed off. No one really knows for sure except for the NDA'd employees at AMC, and maybe (maybe!) Darabont, assuming his long-term plans for the show are still intact after his firing.
I'm not going to keep saying "the actor," so assume that SPOILERS FOLLOW.
