TOPIC CONTAINS SPOILERS
So now half the group is dead... good thing none of the main characters were harmed. Here's what stood out to me the most:
1) Rick and his son had both banned themselves from firearms after last season's events - it seems to have had quite a humbling effect on them and they are starting to seem more human again. Now they've got their guns back and Daryl wants Rick to be the leader again. Excited to see where this goes - the sneak peak at next week's episode showed some weird behavior with Rick.
2) Michonne acted really weird around the baby until Hershel's daughter finally got her to hold the baby.. then we see an emotional breakdown - looks like Michonne lost a child in her past.
3) Someone is sabotaging the camp!?!? We saw at the very beginning of the episode that someone was holding a flashlight and feeding rats through the fence of the camp. Then they discover the rats, and finally we end the episode with someone burning people alive that weren't zombies... WTF
