Shunned by her peers and grounded by her parents, Cady takes full blame for the Burn Book. After making amends with Regina, she joins the Mathletes in the state championship finals to make up for the math tests she failed. Cady answers the tiebreaker correctly, and they win the championship for the school. At the Spring Fling dance, Regina's new boyfriend, Shane Oman, is elected King, while Cady is elected Queen. Onstage, Cady declares that all of her classmates are wonderful in their own way, snaps her plastic tiara, and distributes the pieces to other girls in the crowd. She then reconciles with Janis, Damian, and Aaron, and reaches a truce with the Plastics.
