Plot summary
Struggling with her feelings of uselessness to her sisters, Alison is sidelined in her neighbourhood's carnival celebrations, and her guilt over Aynsley's death resurfaces when Chad shows up at the carnival, leading her to relapse and get high with help from Ramone. Meanwhile Art is forced to assist his partner in searching Alison's house and planting evidence tying her to Pouchie's murder; instead his partner discovers the corpses of Leekie and Rudy under the garage. Donnie collapses while performing a highland dance onstage, after accidentally consuming a drink Alison spiked with tranquilizers.
Alison berates the watching crowd for their hypocrisy in criticising her and her husband, reminding them that most of them bought drugs from her. She then confronts Rachel and demands she call off the police, pointing out that an investigation into Leekie's murder will draw unwanted attention to Neolution and get Rachel into trouble with Westmorland. Alison later decides to leave for a while, with Donnie's blessing.
