Negan played a crucial role in helping Maggie in The Walking Dead: Dead City season 1, but there's another character who can save him in season 2. Negan and Maggie have been at odds since he killed Glenn in season 6 of the main show, but Dead City made them work together. By the end of season 1, Negan found himself separated from everyone he knew, and now he must navigate tough choices in season 2 to avoid more harm.
One likely character to help him is Perlie Armstrong, who was once his pursuer but became an ally. As a New Babylon marshal, Perlie has doubts about the Federation's methods and motives, suggesting he could shift allegiances in season 2. His knowledge from the inside could help Negan stay on top of the upcoming war. Perlie's connection to the New Babylon Federation and his understanding of Negan set him up to be a crucial ally in season 2.
