The narrative was already going to be extremely different in respects to all things Rick Grimes-related, since Andrew Lincoln isn’t around to share the same fate as his comic counterpart, and the live-action TV drama also can’t properly adapt Michonne’s reunion with her daughter from the comics.
If The Walking Dead is reversing course on The Commonwealth’s relatively amicable first appearance in the comic, that could make for a very different arc for the TV show to wrap things up with.
But I still somewhat expected The Commonwealth’s early TV days to be similar in nature, though that might not be the case at all depending on how things play out from here.
Even though the Commonwealth Army’s introduction on the TV show didn’t feature any gigantic game-changing twists, it could definitely have major ramifications in the immediate future.
