Two points i have to say:
1. It seems
Randy really has it out for
Michael. Guess it proves that they can remember their last life when they are a human, or at least the final hours. It shows Randy has a lot of resentment towards Michael, considering he looked right at him before biting
Saul. Man that sucks, swear if Saul dies....
2. Have the zombies gained some sort of Immunity to the gas now? The first time we encounter GZ, no zombies were there, and it appeared they could not enter. Then the 2nd encounter, we see a normal and a crazy/mutated Little one there too. While the gas returns, it seems the Little one is not effected. Then the 3rd "kind of encounter but not really" at the end of this chapter shows the zombies going through it as they please. Have they evolved to use it as a defense, or what?
