In TWD they usually wear ponchos to protect themselves and put the blood and guts on the clothes. This dude was rubbing his whole face in it! It was in his eyes, on his mouth....EVERYWHERE! In one of the talking dead episodes Kirkman was asked something about "why don't they just always cover themselves in walker guts" and he said cause it isn't good for you and you can still get sick and that its a last resort plan. That fact that he was putting it all over himself like it was body wash kind of takes away from the scariness of walkers. I think they should have made Nick be more careful with where he put that blood! I know its a show by the way and not based in reality but they could try harder!
