I found the whole thing with the crazy woman to be very creepy and disturbing.
I really like Rick, and I’m already getting bummed that things are going to go badly for him this season. He has that far away haunted look on his face an he seems like he is barely surviving his PTSD. Then this woman comes along with the ominous message that you can’t come back from the bad things we’ve had to do.
I personally don’t believe that. You can always come back.
