I feel like a fool because I fall for it every time. Thinking these characters can return to normal behavior after they have been fighting so desperately just to stay alive. Still, I loved it and it was very well done.

When everything you need is scarce (be it water, food, shelter, medicine, or whatever), humanity is at its worst. (I thought this episode was a little better than the previous two.)
