Mayans M.C. Season 4: Release Date, Cast, And Trailer

The Deadline report gave a couple hints about where Season 4 of "Mayans M.C." is headed. Here's the teaser in full: "Once the golden boy with the American Dream in his grasp, EZ, his brother Angel, and the rest of the Santo Padre M.C. face retaliation from other chapters after a failed attempt to align under one King. Meanwhile, EZ and Angel have grown distant from their father Felipe after a heart-wrenching betrayal."

"The attempt to align under one king" part refers to the Santo Padre Mayans charter's attempt to assassinate the Yuma charter leader, Canche (Jimmy Gonzalez), only for Canche to survive, prompting Oakland charter leader Diaz (Alex Fernandez) to gun down Ibarra (Mike Beltran), the Tuscon president and one of the Santo Padre charter's main allies. 

The "betrayal" refers to the moment in the Season 3 finale when Felipe convinced Gaby to leave town for Lodi without EZ, urging her to get away from his broken son and save herself.

Since the character Adelita Espino will be returning to for Season 4, most like that means her ongoing storyline about the killing of her son might be another plot point. To briefly recap, Adelita was about to get revenge against Lincoln Potter (Ray McKinnon), the ultra-corrupt U.S. Attorney whom she's long believed responsible for her son's death. In the Season 3 finale, Potter revealed her son isn't really dead. 

Finally, another big development in the Season 3 finale has big implications for the future. Gilly successfully killed the leader of Meth Mountain, only to learn that he was affiliated with the Sons of Anarchy motorcycle gang. That could be setting up a confrontation between the Mayans and SAMCRO, which has been long in the making.
