Realistic horror stan me says that Billy pressured Sidney for sex despite her trauma and would probably do the same to other partners. Fantasy self shipping horror stan me says shut up, he's gonna treat me right
And he did pressure her. It messed with her head with his little “being vulnerable about their relationship”
Loose quote since I’m too lazy to find it, “he has to deal with me so much. A sex anorexic” or something like that. With Billy “opening up” about their relationship isn’t the same since the trauma of her mother which “he understands” and he just wishes she could let loose
She started doubting herself and felt like maybe she should have sex with him to ease some of the tension.
However, I feel like he only did that to fuck with her head once his intentions were revealed. She felt the betrayal after he said something about them already having sex.
So I’m not sure he’d do the same to others unless it’s the same thing as Sidney.
