hides behind unfinished drywall. The attacker finds her and jams the box cutter through the mesh, eventually slashing Katia's stomach and throat, causing her bleed to death. When Bruno goes outside when he hears the killer drag Katia's body, the killer pulls out the blade ready to slash him too. Not noticing Katia right at his feet, Bruno heads back inside, where he finds blood on his pants and receives a silent phone call. Bruno eventually goes over his music tapes, where he hears a woman's voice whispering. The tapes are later destroyed, the diary pages thrown into a fire. Giulia comes to surprise Bruno with a visit, supposedly in between rehearsals.

Linda retaliates by finding the final scene and shredding it with scissors. When Giovanni discovers Katia and Angela dead inside a tank, Linda bludgeons him to death with his own wrench.
