The young woman in the attic, Isla, tells Pip she had been homeless when Elliot offered to let her stay at the house. That evening, he confessed to her that he murdered Sal to prevent the police from investigating him for Andie's disappearance. Elliot lured Sal into the woods, then drugged and killed him before sending the false confession using Sal's phone. He then kept Isla trapped in the house for the next five years. The police arrest Elliot, though he still denies having killed Andie. Realising that Elliot could not have been the one who abducted Barney, Pip confronts him at the police station, and he reveals that he blackmailed Naomi and her friends, having learned about the hit-and-run from reading Naomi's diary. Elliot also shares that he believes Andie wanted money because she wanted to run away from her abusive father, Jason. Pip learns from Jesse, an employee at Jason's recycling plant, that Andie's sister Becca was once drugged with Rohypnol and raped at a Calamity party; Pip deduces that Max used the Rohypnol he bought from Andie to sexually assault Becca. Becca tells Pip that Andie dissuaded her from reporting the assault to the police because it would implicate Andie as Max's drug dealer. Upon learning that Andie had been planning to run away from home, Becca, feeling abandoned, pushed Andie, who was already injured from her struggle with Elliot, and killed her. Becca takes Pip to where she hid Andie's body in a septic tank, before revealing that she drugged Pip's tea with Rohypnol and intends to kill her too, but Ravi and Cara arrive just in time, and the police apprehend Becca. A flashback reveals that, on the day Andie went missing, Sal had been looking for her so that he could support her plans to run away from home. Pip and Ravi ultimately confess their feelings for each other.
