Love the show and the direction they're taking it this season. The group is now in real survival mode, rather than enjoying a fun camping trip with moments of terror. I'm not sure why they would take their only medical person on a dangerous exploration trip. I think I would opt to leave him with the stay behinds to guard them and take care of any wounded that come back. Losing him would be a blow right now with the baby coming (if its coming!?). Armored zombies were an interesting touch in the prison. The show seems to be coming alive now (no pun intended), I hope they keep it up and don't bog down in love stories and marital problems.
