duets competition winners Quinn Fabray (Dianna Agron) and Sam Evans (Chord Overstreet), which upsets Rachel and Finn, while Brittany Pierce (Heather Morris) and Mike Chang (Harry Shum Jr.) are given lead dancing roles on another number. When Brittany admits she is nervous about performing, her boyfriend Artie Abrams (Kevin McHale) gives her a "magic comb" to boost her confidence. She and Mike commence time-consuming rehearsals for their dance routine, and Mike's girlfriend Tina Cohen-Chang (Jenna Ushkowitz) suspects that they are having an affair; when Artie confronts Brittany about it, she confesses that she has been avoiding him because she lost his comb. Artie admits that the comb was never magical, and tells Brittany that she is magic. Kurt attends his first meeting with the Dalton Academy Warblers. He learns that the setlist for Sectionals is selected by a council of upperclassmen, and is offered a chance to audition for a solo at Sectionals. He visits Rachel for advice, and at her recommendation sings "Don't Cry for Me Argentina" from the musical Evita. Kurt is not given a solo, and his friend Blaine (Darren Criss) suggests that he try to fit in rather than stand out. Santana (Naya Rivera) tells Rachel that she and Finn had sex the previous spring, and Rachel is furious that Finn's claim to be a virgin was a lie. Emma counsels them, and then realizes that she should not attend Sectionals with Will since her boyfriend Carl (John Stamos) would be hurt; she and Carl fly to Las Vegas, Nevada for the weekend. At sectionals, the Hipsters and the Warblers perform first, the latter singing Train's "Hey, Soul Sister" with Blaine on lead. Despite much backstage drama, the New Directions set goes smoothly, with Quinn and Sam performing "(I've Had) The Time of My Life" and Santana singing lead on Amy Winehouse's cover of The Zutons' "Valerie"; Brittany and Mike receive several bursts of applause for their dancing. New Directions and the Warblers tie for first place, which means that both groups will advance to the Regionals competition. Emma tells Will that she married Carl in Las Vegas, and despite his shock, Will says he is happy for her. Finn breaks up with Rachel after she confesses that she made out with Puck to get back at him over Santana. New Directions performs Florence and the Machine's "Dog Days Are Over" to celebrate the club's competition
