Interesting. So our newly armed zombie seems to be making his way directly to the school. Does this mean he remembers that the group was planning to go there and is actively hunting them down? You'd think he'd remove his mask so he can bite them... but maybe killing is the ultimate goal, not infection?
And why aren't those school zombies reacting? Is it related to "Them"? Maybe there's another person who half zombie and can control the school zombies.
