I figured that Bob got bit in the gross water, but didn’t let on so as not to upset Sasha. When he went outside,they went to a shot of his gun in his back belt. That led me to believe he was going to off himself in the head so he wouldn’t turn.
I wondered if he was turning slowly due to being an alcoholic. Anxious to rewatch the episode.
I don't think so......If Bob had gotten bit, he likely would have turned within a short period of time.........the abduction in the woods was literally hours after the food storage incident......And he still hadn't turned while his leg was being cooked........
