“The Walking Day” returned with the first episode of the second half of season four, entitled “After” which refers to what happens after the fall of the prison. For some people it was a chance to learn and grow.
Some spoilers follow.
Michonne spent most of her time with her new undead walker posse. It seemed that once again she was bereft of human companionship and was, in effect, one of the walking dead herself. But then something happened and, in a display worthy of “Kill Bill,” she dispatched almost two dozen walkers with her katana. That was a cathartic experience for her. She has decided that she wanted to live.
Meanwhile Carl was being a pain to her dear old dad Rick, the worse for wear, by being a bratty teenager. Carl has reached the annoying age when a young man is flow to overflowing with testosterone, but at the expense of having any sense. He actually comes to believe that he doesn’t need his dad and can survive on his own.
The good news is that he is soon disabused of that notion by almost getting killed twice. The even better news is that he is not killed and lives to realize that dear old dad might be of some use after all keeping him alive.
The payoff for all of this learning and growing happened when Michonne happened to stumble upon the house where Rick and Carl, now happily reconciled, are eating lunch. This scene of normality makes her do something she has perhaps not done since the zombie apocalypse occurred: smile.
Then there was the knock at the door. Rick looked through the eye piece, saw who it was, then turned to his son and said, “It’s for you.” Meaning that Carl now has someone else to interact with and perhaps learn from to save ammunition when cutting down the hordes of walkers who seem to be endless.
