As I suspected, someone is okay.
By now, we know Merle is being set up to be killed by any number of people: Rick--for obvious reasons, Glenn, Michonne and of course his own brother.
Who will earn the chance to take him out?
I can't imagine that there's not going to be a Merle/Daryl showdown at some point. I keep thinking that maybe that's where Carol will somehow play into it.
