At the beginning of senior year, former head Cheerios cheerleader Quinn returned from summer break with much more than just a dramatic new 'do. She also had a new attitude and a new gang, the Skanks. Glee club and academics just didn't interest her anymore. But when Shelby came back to Lima with Quinn's biological daughter, Beth, Quinn decided it was time to drop the bad-girl attitude and get her baby back. She planted fake evidence and accused Shelby of being an unfit mom, until she finally had a change of heart and realized that Beth was exactly where she needed to be.

Although opposed to the idea of a teenage marriage, Quinn expressed support for Finn and Rachel's nuptials. On her way to their wedding, she was texting while driving and was hit by a truck. Unable to walk after the accident, she promised everyone that she'd be singing and dancing by nationals. After much work in rehab, she took her first steps on prom night.

Quinn fulfilled a lifelong dream when she realized that she'd won the election for prom queen, but she secretly gave the honor to Rachel instead. When graduation day came around, Quinn said goodbye to her classmates and teachers and headed off to college at Yale University.
