admittedly, I was only half-watching the second half of the episode. But, what was the story with the scene where Rick was laying on the couch while Carrrrrrrrggggghhhhhlllll berated him for being a total puss. Is Ryyyiiick just a really heavy sleeper? or momentarily dead? in a coma? I mean, Carrrggghhhlll's voice was pretty loud. he just laid there. what was up with that?
Oh also, I didn't realize Walkers could become weak. You know, for a breed that can basically survive any physical trauma, save head removal, it seems kind of weird that they can run low on energy or get worn out. Seems like all Walkers would be more worn out than the one barricaded in the shop, ya know, because they're always hungry and walking around 24/7.
