Negan played an integral part in helping Maggie in The Walking Dead: Dead City season 1, but there's another character who can save him in season 2. Maggie and Negan have been at odds since season 6 of the main show after he killed Glenn, but Dead City challenged this by making them work together. By the end of The Walking Dead: Dead City season 1, Negan found himself separated from everyone he knew personally or had gotten closer to, like Ginny and Maggie. Forcibly enlisted by the newest Dead City villain the Dama, Negan is faced with leaning into his previous ruthless Savior-leading days.
