The next morning, Jo Lynn calls the school and impersonates Tingle, calling in sick. Leigh Ann and Luke go to school, leaving Jo Lynn to watch Tingle. When they return home, the trio devises a plan to blackmail Tingle by using fake photos of Luke and Tingle in bed together. Meanwhile, Tingle plays mind games with Jo Lynn, concerning her jealousy about Leigh Ann's supposed relationship with Luke. Later that day, the plan goes awry when Coach Richard Wenchell, the school's gym teacher and Tingle's secret lover, visits the house. Jo Lynn, again, impersonates Tingle and blindfolds Coach Wenchell to hide her identity. When Wenchell passes out after a high intake of alcohol, the trio decide to blackmail Tingle by producing photographic evidence of her affair with Wenchell. While Leigh Ann and Luke leave to have the pictures printed and take an unconscious Wenchell back home, Tingle reveals to Jo Lynn that Leigh Ann and Luke spent the night together at a party. Distraught, Jo Lynn leaves. When Leigh Ann and Luke arrive back, Leigh Ann berates Tingle for hating her because she has, unlike Tingle herself, the potential to leave town and experience life. Tingle retaliates that she used to be like Leigh Ann and that Tingle herself is Leigh Ann's future. In response, Leigh Ann and Luke have sex downstairs. Later, the two find Tingle's history grade book. Leigh Ann marks down her rival Trudie Tucker's top A grade down to a B, and upgrades her own C to an A+. The next day at school, Jo Lynn ignores Leigh Ann, still hurt over the revelation. Leigh Ann tries to make amends, but admits that she had sex with Luke, further infuriating Jo Lynn. Tingle escapes from her bonds, ties Luke down in her place, and using the loaded crossbow, threatens Leigh Ann. Jo Lynn returns in a failed attempt to persuade Tingle she will help her blackmail Leigh Ann. After a violent fight, Tingle fires the crossbow, hitting Trudie in the chest as she enters the house. Leigh Ann checks her pulse and says she is dead. The principal arrives to check up on Tingle and is horrified by the scene. Guilt-ridden, Tingle confesses that she shot Trudie and wanted to make Leigh Ann fail like Tingle did herself. However, Trudie was protected by the thick textbook she was holding to her chest and is completely unharmed, which Leigh Ann already knew.
