SPOILERS AHEAD SO YE BE WARNED
In this issue The group is dealing with the fact that one of the twins killed the other, knowing that he would come back from the dead. So in his eyes, no wrong was done. The group even debates wether or not to kill the little boy. While most of the group argues the implications, someone among them takes it upon themselves to do what is "necessary".
This is a good and powerfull issue. One of my favorite kind of Walking Dead book. The kind that questions wether normal world morales have any place in a zombie ridden world. Oddly enough, this is also the issue we have a priest walk into the group. That is if he really is a priest, at this point it is too early to tell. Yet it does give us an avenue to discuss the religious aspects of the dead rising from the grave.
It's these kinds of things that keeps this excellent series from becoming stagnant.
