That’s part of how Hilarie Burton came around to playing Negan’s wife Lucille for the Season 10 finale that aired in early April, and at this point, I wouldn’t be surprised if Jeffrey Dean Morgan’s other two kids also joined the undead fun for the upcoming final season.
Considering The Walking Dead is filming Season 11 while adhering to strict COVID safety protocols, it definitely makes sense for the producers to look closer to home when sourcing actors as extras and guest stars.
After all, it’s a lot easier to cast someone who’s already necessarily in the quarantine bubble than it is to only seek actors outside the show’s immediate periphery.
