The detailed season 6 clip takes the viewer inside the confines of the Alexandria Safe Zone, where Rick Grimes and the other survivors have taken refuge.

Over the course of the teaser, however, it's Grimes who emerges as the most unhinged, painted as the bad guy who's causing all sorts of rifts in the encampment. It soon becomes clear that Grimes and character Morgan James will be engaged in a major power struggle in the new season.
