Ok so for those of you who read the entertainment weekly article and for those of you that haven't they pretty much say merle will be a hero in season 3 for woodbury. so with this i was thinking what if merle is a replacement for caesar martinez
he is probably well trusted by the governor
he will be trusted by daryl and by rick (to a much lesser extent) so he will be able to convince whoever to follow him out of woodbury.
after he gets presumably caught (depending if he is a replacement for Caesar) he will be able to be killed by daryl (who cements his loyalty to rick and also a god moment for a mid season finale) or joins rick's group via daryl's support
I personally think they take the caesar route with merle except have him join rick.
so i would like to hear everyone's ideas about this
