Glenn's death will impact the upcoming spinoff of The Walking Dead, titled Dead City. The show follows Maggie and Negan as they search for Maggie's kidnapped son, Hershel, in post-apocalyptic Manhattan. Despite Negan previously murdering Glenn, Maggie and Negan form an alliance due to their shared connection to that event. The showrunner, Eli Jorné, researched stories of difficult forgiveness to inform the characters' arcs. While tension between them remains, the opportunity for forgiveness and growth is present. The Walking Dead: Dead City premieres on June 18th on AMC.
