Mayans MC co-creator Elgin James knew how he wanted to end Season 3 soon after finishing Season 2

Deadline

"What’s wild is that we finished Season 2 and then the hiatus, at least for me, was about a week and a half, and then it was like, 'We need to start Season 3!'" he tells Deadline, speaking of this week's season finale. "So, it took off and I was just like, 'I need to figure this out.' By the time we started the writers’ room, I knew our first scene and the last scene, and I just needed the help of the brilliant writers to…piece it all together. But we knew pretty soon on, where we were going to end."
