One Reddit user shared a theory that ties back into events from Season 2, and it’s very interesting. The user pointed out that the bite is in a pretty ironic area, writing, “The location of Carl’s bite mark is in the same area where he was shot by Otis, where Herschel did surgery to remove bullet fragments, back in Season 2 Episode 2, Bloodletting”. This was back when the group was searching for Carol’s daughter Sophia, and Carl was accidentally shot in the stomach while approaching a deer in the woods. What does this have to do with his bite wound you ask?
Another user asked the question, “Maybe the scar tissue will stop the infection from spreading?”
Hmm? Maybe, just maybe!
