I have my first nitpick in series history:
Merle calling Maggie "the farmer's daughter." How could he have known that? He hadn't talked to her yet and she surely wasn't going to tell him that nor was Glenn. That was a pretty correctable mistake they let slip in.
Overall a great episode. The tension was off the charts everywhere. LOVED the music at the end. Thunderous pulsating beat just amped up the tension even more. Cannot wait for Rick and the Governor to get face to face.
Oh and nice thong Andrea.
