"Spoiler alerts," he said. "I knew what was going to happen. So I would only try to read my part." As he's previously noted, when taking the role, he did so knowing it'd make his father happy, since he was a fan of the show.

"I thought the show is so much about that father-son relationship and I just wanted to do something to make my dad happy, and I just thought I was gonna get a song on the show," Manson said, noting that his mom had died shortly after the news. But Katey Segal, wife of showrunner Kurt Sutter, had other plans.

"She said, 'Do you want to act?' and I said, 'yeah, that would be amazing,'" Manson recalled. "That was earlier in the meeting, when I was sort of worried about my father because he was also ill and I was trying to cheer up my dad. This is before my mother had died. So I went to Ohio because my mother had died and I got the phone call that I was going to be on the show. I said, 'Dad, guess what, I'm going to be on the show. Guess what, I'm going to play the head of the Aryan Brotherhood. Guess what, I get paid for it. Guess what, I'm in every scene, every episode that I know of.'"
