Oh, I liked how this episode started. I honestly think that one of the best way to survive a zombie apocalypse is to start eradicating walkers whenever they're in a group which survivors can take down. So take the best fighters, who know how to survive against walkers and start clearing up the area so you don't get something like what happened to Dale.
I liked how this episode ended too. About time the Shane & Rick thing came to a head, although I honestly didn't think that Rick would kill Shane. I thought he'd kick the man out of the group.
