I googled Glenn’s “death” and they had still photos that show Nicholas’s hands on Glenn’s shoulders so those would be Nicholas’s guts. But how do you keep perfectly still and completely concealed under a dead guy being gorged on by zombies
But I think they only eat the gut bag and the skin. We never see any completely eaten bodies..
My theory is that he didn’t need to keep perfectly still or concealed under the dead guy once he had enough blood on him.
He just appeared as another zombie to them at that point.
It’s just a theory though, a needle threader, because I don’t want Glen to be dead.
