So I've been looking into why amc hasn't shown us the iron in action at the sanctuary, I am beginning to think they are going to surprise us and iron Daryl. Because I don't think they will kill another major character in the first half of season 7 because the Glenn and Abe shock factor is still there, but the mid season finale is going to have to be big am I right. Some clues also, the mid season finale has been named "Hearts still beating", remember getting the iron won't kill you, but it will mess your face up. Also, Daryl has been kind of disobedient in Negan's eyes. And I don't think negan will tolerate it much longer. I am pretty sure I am the only one to come up with such a random speculation, but it could work, it would make sense for the writers to throw us another curveball, right?
