When a sore throat affects Rachel's singing voice, she goes into panic mode and Finn takes her to the doctor in order to find out what's wrong with her, not without trying to show Rachel how much he still really likes her. Meanwhile, Kurt tries to change his personality to impress his father, and Puck makes a strategic move to elevate his social status by dating Mercedes after his mohawk is cut off.
In the beginning of the episode, Puck's mother notices a mole on his head and he is subsequently forced to have his mohawk shaved off. He discovers he is no longer considered a credible bully, and also realizes that Mercedes has become popular since joining the Cheerios. He resolves to date her to seem popular again. Rachel tries to sing The Climb but lost her voice in the middle of the song.
Mercedes initially attempts to dissuade him, but after singing a duet of The Lady Is a Tramp, she warms up to him. Quinn has a talk with Mercedes and admits she's afraid of Santana's reaction to her and Puck's relationship. Puck's former girlfriend Santana is jealous, and she and Mercedes sing The Boy Is Mine. When Mercedes realizes that Puck has reverted to being a bully, she concludes that being a Cheerio isn't who she is, breaks up with him, and resigns from the squad.
Rachel suffers from tonsillitis and is afraid to have surgery, believing that her voice is her only asset. Finn, who accompanies her to her doctor's appointment, tells her, "There's like, so many awesome things about you." When she consults him on whether to have the surgery, he sarcastically says "Why don't you ask your boyfriend. Oh wait... you can't because he's not here," but he also says, "When are you going to realize that he's not into you like I am?" He tries to tell her that he loves her more than Jesse, but she doesn't listen. He then expresses his feelings by singing Jessie's Girl.
To put her fear into perspective, Finn introduces her to his friend Sean, who was paralyzed from the neck down during a football game. Rachel recovers and offers to give Sean singing lessons.
Kurt is jealous of the time his father, Burt, is spending with Finn, and attempts to emulate Burt's personality. He takes the glee club's "Voice" assignment as an opportunity to change how he is perceived. He sings John Mellencamp's Pink Houses during rehearsal. Brittany thinks
the performance was "hot" and asks if the new, straight Kurt would like to "tap this;" Kurt is the only boy in school she hasn't made out with, and a perfect record (of making out with all the boys at the school) is important to her.
Later, as they are making out on the couch, Kurt asking Brittany what boys' lips taste like? Burt walks in on them, and although he is confused by his son's change in attitude, he tries to assure Kurt that he will love him no matter who he chooses to be.
Frustrated and hurt that Burt is continuing to spend time with Finn, Kurt reverts to his former personality and sings Rose's Turn. Burt overhears his performance and reassures Kurt that, despite the difficulties, he loves him and wants him to be himself.
Rachel returns to Sean's house to give him some vocal coaching. Rachel reveals her voice is back and they start singing One, which is then also performed by New Directions.

We all know that my job here is to look hot.
Nobody quits the Cheerios. You either die or I kick you off.
See, that's the problem with your generation: you're obsessed with labels. So you like show tunes. Doesn't mean you're gay. It just means you're awful.
Rachel, I think you've lost your voice.
I'm like Tinkerbell, Finn. I need applause to live!
Puck: Girl, you got more curves than a Nissan ad.
I'll have to take to the mic and deliver a diatribe. Probably something about immigrants.
I need you to respect my privacy. Brittany and I were just having sexual relations.
