13 Reasons Why tells the tragic, unsettling story behind Hannah Baker's suicide. Each episode of season one is associated with a cassette tape, and each tape names an individual whose actions contributed to her death. Tape 9 addresses Justin Foley - his second in the series - but the events revealed on that tape largely refer to a girl that Hannah chooses not to name: "You'd been with the same girl all night," Hannah explains. "But I'm not gonna call her out by name even though, if you were at that party, you already know."

The party in question is the back-to-school celebration thrown by Jessica Davis at the start of their junior year. She and Justin met during Summer school and spend most of the evening groping each other. Eventually, they make their way to Jessica's bedroom to have sex, but it quickly becomes apparent that Jessica is too drunk to consent.
