All the Events From Season 3 of 13 Reasons Why in Chronological Order

Before the homecoming game, Chloe tells Bryce that she was pregnant, but she got an abortion and Zach had been there to support her. Bryce gets revenge on Zach by attacking him during the homecoming game brawl, blowing out Zach's knee and effectively ending his football career.

Later that night, after visiting the hospital, Zach goes down to the pier where Bryce is supposed to meet Jess. He attacks Bryce in return, smashing his knees and throwing his phone in the water. He leaves Bryce badly hurt but still alive.
