There has been an online fan-theory that Nina may have been sexually abused by her mother - Erica. There are two scenes from Nina's point of view that hint at this theory: When Erica is in Nina's bedroom she gives a suspicious smirk when saying "Are you ready?" and it is revealed Lilly never actually slept over in the Lesbian scene, and Lilly calling Nina "sweet girl" - the same words Erica uses - and Lily's face transforming into herself and her mother causing her to freak out for a second.
