They brought back the cover ourselves in zombie guts technique again. Seems like they can use this whenever writers write themselves in a hole now. "Well shit Bob, how the hell can we get Rick and co out alive this time? They are completely surrounded and outnumbered 1,000 to 1, there is no way they can escape?". "Zombie guts, Ted. Zombie guts". "Brilliant. Glad we can always fallback on guts! Too bad they are too stupid to wear zombie guts clothing 24/7!"
They are all infected. Wearing gut clothing hasn't hurt them.
Plus they wouldn't literally need to wear it 24/7, just when they leave their settlement for whatever reasons. Makes for safe travel.
I also noticed the first time around they literally had guts hanging around their necks, it was gruesome. This time? Perfectly spread Blood covered shirts was all it was basically.
