A very good episode.
I appreciate what Rick is going thru and I was glad he did admit, out loud, that he is seeing things and that he doesn't know what to do about it. But I feel and HOPE the shoot out has brought him back to the real world for a little bit. It is apparent we do need all hands on deck, including Merle and Tyrees group. And the Gov may have been having fun, but he didn't see the WHOLE group, so he may be surprised the next time he comes by for a visit.
Truck to Zombie head Kill was AWESOME!!
I was surprised that Michone had a gun, but when it came time to play and go for Rick or Hershel, she pulled out her tried and true weapon.









LOVED that last scene. Really, loved the whole episode.
But as to your points about the Gov's shooting skills, he was really aiming on that first shot and after that, he was just loving the fact that he scared the prison group senseless. He wasn't even aiming, just spraying the walls. Dude is terrifying when he gets in that mode. And that truck full of zombies was an awesome idea.
