Will separates the group for another mash-up competition. Kurt, tired of being harassed by Karofsky, spies for New Directions at Dalton Academy, where he meets Blaine. Blaine encourages Kurt to stand up for himself. Coach Beiste discovers the boys use her as a turn-off method and attempts to quit her job. Puck returns and develops a friendship with Artie through his community service project.

After Will learns of Emma's newfound love for The Rocky Horror Picture Show, he impulsively decides to have the glee club perform it as the school musical. However, problem after problem, including Sue going undercover to expose the boundary-pushing club on television, prevent New Directions from performing it in front of an audience.

When New Directions wants to perform a Britney Spears number at the Homecoming Assembly, Will is reluctant to go that edgy. At the same time, Brittany, Santana, Rachel, and Artie all go to Emma's new boyfriend Carl's dentist office to have their teeth cleaned, and experience Britney Spears fantasies while under anesthesia.

Kurt's father, Burt, invites Finn and his mother to move in, but Finn is reluctant to share a room with Kurt. He uses a homophobic slur against Kurt during an emotional outburst, and is told to move out by Burt, but later comes to Kurt's defence when he is attacked by school bullies.

Believing the glee club members are becoming complacent ahead of Sectionals, Will pits the girls against the boys for a mash-up competition. Terri takes a job as the school nurse to stop Will becoming closer to Emma. With encouragement from Terri, Ken proposes to Emma, who reluctantly accepts. Terri gives the glee club pseudoephedrine tablets, enhancing their mash-up performances. Rachel and Finn feel guilty and confess, resulting in the competition being nullified, Terri being fired, and Sue being appointed co-director of the glee club. Quinn agrees to let Terri secretly adopt her baby, enabling her to continue faking her pregnancy.
