I liked the episode. it was a lot of set up but that was necessary to show how life at the prison has changed over the last few months with the influx of new people and the change in leadership.
Could have lived without Rick and the crazy chick in the woods stuff which was the only let down of the entire episode to me. We don't really need more soul searching with Rick Grimes. We get it...dude is sick of the violence and the pressure of leading the group and he wants to try to give his son as normal a life as possible before the kid turns into a psychopath. Spending half the episode on him and some crazy Irish bytch was not cool. They should have just had Rick ignore Herschel telling him to take his gun and then get ambushed by a group of walkers and having to fight his way back to the prison with just a knife. That would have been way more interesting.
D'Angelo Barksdale is a herb whether in the mean streets of Baltimore or the zombie apocalypse. I am going to enjoy watching him get eaten by some walkers.
That scene in the store where it was raining zombies was a cool as action set piece. I was shocked to see Kyle Gallner's character be the one who got eaten since he is sort of a "name actor", I was expecting Sasha to die.
And I am assuming that someone in the prison is who has somehow infected Carl's nerdy friend (somehow getting hold of some zombie blood and poisoning the kid with it). I hope it is D'Angelo Barksdale and he is working with the Governor to ruin the prison from the inside.
