One thing that irritates me, and has since the first episode, is that the Zombie virus/bacteria appears to turn the skull, whether alive or dead, into wet cardboard. The ease at which everyone can stab any object, from a tree branch to a nail file, into someone's skull is ridiculous. Last episode zombie heads were bursting open simply by walking into the corrugated metal fence. This episode our stalwart heroes are stabbing the Unfair Wolves in the brain with no effort whatsoever.
