Dusty visits her family who has a protective order against her after she threatened one of them. She's picked up by Detective Bentland who informs her that she's aware of the fact that Dusty and her pals have decided to blame Warren Glowatski for Reena's death. Bentland gives Dusty ample opportunity to tell the truth, but the frightened teenager doubles down and claims Warren was solely responsible.
After hearing Kelly joke about how she held Reena's head down under water while smoking an entire cigarette, Dusty snaps and attacks her. Josephine and Kelly decide that Dusty can't be trusted. Before heading to a school dance, Joephine and Kelly put rat poison in a bottle of iced tea mixed with vodka. Already drunk, Dusty vomited after taking one sip.
Feeling desperate, Kelly and Josephine drive her to a train track where she is almost convinced to take her own life before Josephine stops her. It's unclear if Josephine herself is feeling guilty but none of that matters. The three of them, along with Warren and two other girls are arrested. Dusty may have lived but her life could be over in other ways.
