Mayans M.C. Season 4, “When the Breakdown Hit at Midnight,” ends with a mysterious arsonist burning down a warehouse filled with drugs owned by Soledad and Miguel Galindo. The action will certainly have major repercussions for the Mayans M.C., as EZ Reyes — the newest president of the Santo Padre chapter — was relying on that heroin to make the money it needs to beat the Sons of Anarchy. So the question remains, just who burned down the warehouse?
The first possibility is Isaac Packer, who was a major villain in Mayans M.C. Season 3. The Sons of Anarchy member/Meth Mountain leader is notoriously unstable and proved in “When the Breakdown Hit at Midnight” that he’s willing to do terrible things to win the war with the Mayans. Isaac’s particular shtick in the episode is fire, and he promises that a fire is coming for his enemies. As such, it’s not impossible that Isaac was the one who burned down the warehouse.
Still, whoever burned down the warehouse seemingly acted alone, and considering Isaac’s standing with the Sons of Anarchy, he seems unlikely to do the deed alone, especially in the event that there was security at the location. Isaac also wouldn’t necessarily need to hide his identity, as he’d almost certainly want the Mayans to know that he was the one who destroyed their drug supply. Finally, the arsonist doesn’t quite move like Isaac or resemble in him physically, making it unlikely that he was the one who did it. It’s possible Isaac hired someone to burn down the warehouse, but that still doesn’t answer why that arsonist would go alone.
The most likely possibility is then Angel Reyes. In the latter half of Mayans M.C. Season 4, Angel has become increasingly disturbed by EZ’s actions, which he expresses to him in a meeting at the temple. EZ makes clear he won’t tolerate any dissent from his brother. This may play into Angel’s motivation, as he might want to keep his brother from falling any farther. Angel also now has a family, and there’s a chance he’s afraid that the war will spill over, hurting them in the process. Despite his often flawed methodology, Angel does have a moral compass that at least tries to get him to do the right thing, and that might be what influenced him here.
Outside of motivation, Angel also has the means to have committed the crime. As a member of the Mayans M.C., Angel would have likely known where the warehouse was and had some insight into security at the building. Additionally, the arsonist physically resembles Angel from what we see of him. So while it’s not confirmed at this time Angel actually is the arsonist, there’s a very good chance he’s the one who burned down the warehouse, which could cause major problems with the club if they ever find out what he’s done.
