One character exposes another character to paraphilia. One character (implied to be an adult) is a sex worker to older teen clients. He is emotionally stunted from sexual abuse and recreational drug dependency so his soundness of mind is in question when he nominally consents to sex work. One character suffers emotional incest and sexual coercion from his older brother, and this remains unresolved. In the book, it's implied that these are all reconstructed suspicions or fantasies, including violent murders, but the film adaptation keeps ambitious which events might have happened in the story.
