(IMO) the entire point of the episode was how the people would handle the aftermath of the mid season finale. Carl behaved like most kids that age would and went off his rocker blaming everyone else for the situation, before realizing he needed his dad more than ever right now. Rick had to realize he couldn't protect Carl from the reality of what life is for them right now. I think we start to see more of a real father-son partnership develop between those 2 the rest of the way.
Michone had some other...issues....to work out on her own and she's now realizing that she needs people around her. I think the combination of her dreams/memories and seeing the woman walker, who looked somewhat similiar, just wandering along with no real purpose made her feel like that's what she would become without people around to support her and give her purpose.
