That was the worst scene of the episode.
Rick backing the truck up to the edge of the lake. Why?
Rick acknowledging that the guy saved Daryl's life -- presumably because he saw it unfold, yet didn't care to a) dispose of the walker before it got to Daryl, or, more realistically if he was far away, b) yell at Daryl to watch his back.
Oh, and what happened to the black Chrysler 300 they had? They just ditched it in favor of the truck? Why not have one person driving each vehicle?
Stupid. Stupid. Stupid. It's stupid shit like this that makes no sense other than to advance lazy story writing that detracts from the rest of the show.
At least Rick is slaying pussy like no other in this post-apocalyptic world.
