Little is known about this factory before or as the apocalypse began.
Maggie, Alden, and Negan rest up at this factory while they check how far away Arbor Hills is. As they begin to move, they hear Agatha screaming as she fights the undead. They help her and she takes them to a dying Duncan. Maggie apologizes for having gotten him into this situation and Duncan makes Maggie promise to get Agatha back home safely. Duncan dies from his injuries and Maggie tearfully stabs him in the head so that he doesn't turn.
