The Walking Dead - 2x07 - Pretty Much Dead Already

    The group is told about the barn.  Dale continues his issues with Shane.  Rick helps Hershel lead two new walkers to the barn.  Shane decides that he has to take command of the situation, and distributes weapons, and opens the barn.  The last one out is Sophia, who is shot in the head by Rick.
    It's hard to remember a lot of what happens in this episode, since it all melts away from the final sequence.  What I do remember is that Dale is really, really bizarre in this episode.  He tries to hide their guns, and assumes that this will accomplish something.  But it doesn't make any sense.  Does he consider that everyone in the group would disagree with him?
    The twist at the end of this episode is what makes this half season worthwhile.  But I have to say, the second time through, it doesn't seem to be nearly as impressive.  The only thing that Sophia's reveal does is give them an excuse to leave the farm.  It doesn't feel like a surprise, since most viewers would reasonably think that she's dead if she hasn't come back in a few episodes.
