There is a depiction of the violent rape of a 16 year old girl by three male assailants who look like they're in their 20's. The survivor of the rape never tells anyone - what happened to her is revealed in flashback. But even though she was raped - at her 16 year old birthday party by three adult men, while bullies from her school watch and mock her - she never gets medical treatment, never gets counseling, never gets any support at all. It's like one message of the show is - if you are traumatized and brutalized, walk it off. Don't tell anyone, don't get help dealing with it, just keep it bottled up. It's a very destructive message for a tv show, really sick imo.
In the final episode it's revealed that when the main character was 16, she was raped by three adult men. It isn't graphic but highly disturbing. We see her restrained, before the camera cuts away. She's screaming and crying.
Full spoiler - 16 year old girl, violently restrained and crying for help as three men hold her down and one starts to unbuckle his pants, Only women are ever held accountable for any of the crimes in this show, the three actual rapists are never addressed at all.
