Didn't Rick decide last week that he wasn't going to hand over Michonne because it would be wrong (and the Governator would kill them all anyway?) But this week he's all "let's hand over Michonne lol" until Lori's Ghost talks him out of it?
It's just annoying when characters seem to get moved around by the plot rather than characters moving the plot. Like with Merle. Yeah, his death scene was really good, well acted, well directed, well shot, thrilling...but he's been an utter shit up until now. So the "MAYBE HE'S NOT SO BAD" bit didn't ring totally true. Maybe if they'd shown some sing of it earlier, but in show time he was being racist about Mexicans about four days ago. Still, good scene...
Of course since Merle was, it turns out, a tactical genius who managed to kill eight of the Governors' men by himself, if he'd only teamed up with Rick, Daryl and Michonne they could have killed all of them.
