1) If the Governor was really trying to protect Meghan and Lily, he would've barricaded them in the camper or an abandoned building or left her sister behind as well for protection. There's no way Meghan should have been left so far away from mom. At the very least, she should've been on top of the camper with her.
2) It was a bit far fetched that the Governor could rally those people so quickly to become killers. Even if they accompanied him to threaten the prison, thinking it would end without bloodshed, there's no way they storm the prison like they did once bullets started flying. Just like his Woodbury group did at the end of season 3, and like Lily's sister did in this episode, most would've retreated to safety when people started dying.
3) So bullets can pass through Bob in this episode but not through Darryl's rotting zombie-corpse shield?
4) Two small girls who probably never handled a firearm before, fire two perfect headshots (between the eyes no less) the first time they pull the trigger on one? The surprise of the kickback alone would've been enough to cause them to miss. Don't get me wrong it was a great moment. I even stood up in my living room and cheered. But come on...
5) At long last, Michonne puts her katana through the Governor, whom she spent months on the road searching for, only to leave him alive? They should've at least had her suddenly get surrounded by zombies or shot at, forcing her to abandon the final blow. Otherwise, it just doesn't make any sense.
