The first teaser for “The Walking Dead: Dead City” season two was revealed at the “Walking Dead” panel at New York Comic Con. And that teaser promises a big return…specifically that Lauren Cohan’s Maggie and Jeffrey Dean Morgan’s Negan will hit TV screens in Spring next year. The panel included the cast of “Dead City.” They revealed the upcoming season will see Maggie and Negan on opposite sides in a war for control of post-apocalyptic Manhattan. It was also hinted that some fan favorite characters may make an appearance as the series progresses…but it was, unsurprisingly, not revealed who fans should be on the lookout for.
