Pretty sure before they found the prison they covered this and someone made a comment on the show about how good they had gotten at killing zombies based on the months they spent wandering between the farm and the prison..I liked it when the zombies actually posed a meaningful threat. Now Pouty gets out of a car and is surrounded by them and escapes without a scratch.
I know now they just treat them like bugs they swat then they get in the way. They only worry about them when they swarm.
