Something else, as far as continuity, the doctor or someone explained every walker was reduced to their most primitive urge to eat. We've seen they can't climb, use tools (except maybe turn a door knob), are attracted to light and noise, aren't capable of any defensive actions, yet in one of the first episodes, a little girl walker stopped to pick up a doll.
