In this episode, It begins with Max experiencing the consequences of her time-traveling mistake at the end of Episode 3, where she saved William’s life and created an alternate timeline. In this reality, Chloe is paralyzed from the neck down and living in constant pain. After a heartbreaking conversation in which Chloe asks Max to end her suffering, Max realizes she must undo her actions and return to the original timeline, allowing William to die so Chloe can live the life she was meant to. Back in the restored timeline, Max and Chloe resume their investigation into Rachel Amber’s disappearance, piecing together clues that lead them to a hidden underground bunker on Prescott farmland. Inside, they uncover the sinister Dark Room, a place used to drug, photograph, and exploit girls, with chilling evidence showing Kate Marsh and Rachel among the victims. Following the trail, the girls discover Rachel’s buried body in the junkyard, confirming her death and leaving Chloe devastated. Believing Nathan Prescott to be responsible, they attend the Vortex Club’s “End of the World” party to confront him, but he never appears. Instead, Max is drugged and awakens tied up in the Dark Room, where the shocking truth is revealed: it is not Nathan but Mr. Jefferson, her trusted photography teacher, who is behind the crimes. This devastating twist not only reframes the investigation but also solidifies Episode 4 as the emotional and narrative breaking point of the game.
