Sue has fallen into a deep depression since her loss at the Cheerleading Regionals, which had cost the Cheerios a spot at nationals. She attempts suicide (Sue-icide) by eating gummy bear vitamins, but is suitably unimpressed when they don't work. Emma suggests to Will that he invites Sue to join the Glee club for a week to help her get out of her funk. Initially skeptical, Will eventually warms up to Sue and notices the Glee club has a positive effect on her. However, Sue secretly reveals in her diary that she wants to destroy the club from the inside. She does this by attempting to turn Mercedes and Rachel against each other. Angry, the girls have a vocal "Diva-Off" at glee club rehearsals and sing Take Me or Leave Me. However, they admire each other's singing during the song and become friends again, to the dismay of Sue.

Sue becomes annoyed with the students' efforts at singing anthems, which will be the theme at Regionals. Sue and the rest of the club sing a song of her own choosing. Finn and Rachel lead the club members and Sue in a rendition of Sing by My Chemical Romance. Ultimately, Sue becomes a fan of the 'music within me' and takes a part-time position as the coach of Aural Intensity, much to Will's horror.
Meanwhile, Rachel dresses Brittany in her own signature style of conservative dress to her make a social comeback at McKinley. This starts off with one article of clothing which was leg warmers, but Brittany wore them on her arms because she was cold. Rachel demands for Brittany to dress exactly like her, and informs her to go to Kids "R" Us. That next day Brittany Comes into school dress head to toe like Rachel, and Rachel tells her to tell everybody she is just copying Rachel Berry. This plan backfires when the rest of the female student body dresses like Rachel but claim that it was Brittany that made the style trendy. Sam forms a Justin Bieber tribute band to impress Quinn, and sings Baby to woo her from Finn. Earlier, Quinn lied to Sam that she did not kiss Finn but had saved his life by extracting a gumball from a choking Finn's mouth. Artie and Mike are concerned that their girlfriends are coming down from a "Valentine's Day high" and Puck wants to impress Lauren, so they join The Justin Bieber Experience. Together they perform Somebody to Love, and the boys suitably impress their girlfriends who show their affection. When Lauren becomes nervous about performing for the first time in front of the glee club, Puck suggests that during her solo she should imagine they are all wearing only their underwear. Starting off timid, Lauren eventually confidently sings I Know What Boys Like to the rest of the Glee club.
Santana confronts Sam about his relationship with Quinn. She explains to Sam that he knows Quinn kissed Finn but that he was willing to believe her story to stay with her, and that he has an opportunity to show everyone that he is not a pushover. Santana then proceeds to proposition Sam. Quinn was impressed by Sam's Bieber-inspired performance but Sam confronts her about her encounter with Finn and states that he is now dating Santana.

Rachel, I'm gonna give you some tough love right now. You're not a trendsetter. When people look at you, they don't see what you're wearing; they see a cat getting its temperature taken, and then they hear it screaming.
Despite the fact that your mouth to face ratio is way off, you still somehow manage to be cute.
I wants on them froggy lips, and I want on them NOW.
You know... I really like the Rachel that I saw in there today. Reminded me of the old you. Focused and take no prisoners. I think she might be making a comeback.
