Hi, I'm also coming out of lurkdom! I enjoy reading here because of the thoughtful discussions about my favorite show/obsession. I watched this episode, but haven't had time to pick through it and watch more carefully.
I agree that Rick has PTSD and is reacting to that. I'm sure they all do. He's definitely still their leader, but listens to reason. Michonne got to shine in this episode, which was nice. I loved Glenn with the RV battery; I thought it was well done and subtle. I do love Daryl, even though I know a lot don't care for him as much anymore. I liked how he stated his opinion..."this barn smells like horse shit." Maybe he'll get some of his old wise ass personality back soon. I even liked the bit with Rosita and Red in the camper. In his own weird, gruff way, he was showing his concern.
I'm hoping this community allows them to regroup and rest, if even for a short while. They need it after how we saw them last week, just completely beaten down. I agree there have to be some good people out there. I can also see how the crazies would be out in full force, though. Just think of all the people out there who need medication to function in today's society, whether for depression, anxiety, schizophrenia (which we saw something like that with Lizzie) who are not able to take their meds anymore. I say "crazies" affectionately since I'm one of them and so are a lot of people I know! I don't think I'd go all cannibal, but without my medication, I'd be depressed.
