i might've added that credit after you first glanced! but thank you for catching it. he was real method in that one, and bash & him went from having kind of a director/muse creative love fest to kind of hating one another over the course of filming. ben got kind of psychotic about perfection ala his character, and also jealous of bash? since ben was still making short films, and bash was only two years older than him with a lot less years in the business. ben can completely admit he was an asshole on that set (he wouldn't have been to her, but i assume she witnessed it or just heard about it), so it's possible she wouldn't have totally been excited to work with him again? but he would've been a much warmer/fun (if not way too wild) person on american honey.
love her back story! he would never talk about it, but he obviously hardcore loved her dad's band at some point in his life. if she was ever a delicate ball of emotions around him, that kind of energy would really soften him. whiplash, i'm sure the days she was there was a breath of fresh air for him. like he'd focus on her instead of his own shit
