Michonne is definitely was definitely having a nervous breakdown, I'm happy she found them in time.
Carl proved to me how mediocre of an actor he is this episode. I never thought the guy playing him was a good actor but he never had a enough time to actually show me what he can do. During that scene where Rick was on the couch and he was yelling at him I realized he's not a good actor. For a kid in that situation feeling those things, in my opinion he didn't portray it well, it wasn't real.
Also I didn't like his temper tantrum he was throwing, I realize that they've lost a lot and it's frustrating but this whole "I can take care of myself" thing is a fail. He thinks because he has a gun that he's a big boy now, false. There's a lot of things he doesn't understand about surviving in that atmosphere that he portrayed during the episode.
1. Conserving bullets. Not only does shooting attract more attention but he lacks the physical strength to kill a zombie with say a stake or something more stealthy. He needs someone to help him, as you see he quickly ran out of bullets in his gun in just a couple of hours. He wouldn't survive on his own.
2. He has very poor judgement in situations.
3. He's not very good at being aware of his surroundings
I still liked the episode despite this, not one of the best but decent.
