Sebastian makes a second try for Blaine.

The race for McKinley High Senior Class President comes to an end, and someone is caught trying to fix the results. Coach Beiste challenges Sue over Cooter, and Sue's own election day arrives.

Sue's Nazi-hunting mother Doris Sylvester pays her a visit due to her upcoming wedding to herself, Finn and Kurt face the marriage of their parents, and the administration takes a stand against Karofsky which leads to Kurt leaving McKinley High.

Will becomes ill, and is replaced by substitute teacher Holly Holliday. Meanwhile, Sue takes over as principal when Figgins also takes ill, and flexes her power on campus.

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 Puck goes to juvie, New Directions welcomes Sam as a new member and Will assigns a duet competition for the week. Finn and Rachel throw the competition so that Sam will feel welcome. The love triangle between Artie, Tina, and Mike develops, as does Santana and Brittany's relationship.

Rachel finally meets her mother by accident during a sneak-in on a Vocal Adrenaline practice session, but neither feel an immediate mother-daughter bond. 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.

First I was afraid I was petrified Kept thinking I could never live without you by my side But I spent so many nights thinking how you did me wrong I grew strong I learned how to carry on and so you're back from outer space I just walked in to find you here with that sad look upon your face I should have changed my stupid lock I should have made you leave your key If I had known for just one second you'd be back to bother me Go on now go walk out the door just turn around now 'cause you're not welcome anymore weren't you the one who tried to hurt me with goodbye you think I'd crumble you think I'd lay down and die Oh no, not I I will survive as long as i know how to love I know I will stay alive I've got all my life to live I've got all my love to give and I'll survive I will survive It took all the strength I had not to fall apart kept trying hard to mend the pieces of my broken heart and I spent oh so many nights just feeling sorry for myself I used to cry Now I hold my head up high and you see me somebody new I'm not that chained up little person still in love with you and so you felt like dropping in and just expect me to be free now I'm saving all my loving for someone who's loving me
