Tina in the Sky with Diamonds

New Directions continues their two-week assignment covering the Beatles. Tina Cohen-Chang (Jenna Ushkowitz) is nominated for prom queen at the new combined all-grades prom and is determined to win, dumping Sam Evans (Chord Overstreet)—who she had previously accepted as her prom date—to capitalize on the potential votes of girls without dates, and belittling her assistant and campaign manager, Dottie Kazatori (Pamela Chan). Although she is also nominated, Kitty Wilde (Becca Tobin) decides to support Tina. Upon learning of this, Bree (Erinn Westbrook) campaigns for Kitty, a fellow Cheerio, without her consent and ropes Dottie into a scheme to humiliate Tina at prom.

At NYADA, Kurt Hummel (Chris Colfer) performs "Get Back" to cheer up Rachel Berry (Lea Michele), who is depressed by her disappointing "chemistry" audition for Funny Girl. At the diner where Rachel and Santana Lopez (Naya Rivera) work, one of their co-workers, Dani (Demi Lovato), is interested in Santana; the interest is mutual, though scary for Santana, and Rachel gives her a pep talk before making herself scarce at the end of an overnight shift. Dani and Santana perform "Here Comes the Sun" and, after walking through the city, they share a kiss.

Principal Sue Sylvester (Jane Lynch) hires college student Penny Owen (Phoebe Strole) to become McKinley High's nurse, and Sam develops a crush on her, singing "Something". When Sue decides to fire Penny for incompetence, Sam overcomes his fear of needles and allows Penny to give him a meningitis shot, and later praises her to Sue, who reverses her decision.

At prom, Ryder Lynn (Blake Jenner), Marley Rose (Melissa Benoist), Jake Puckerman (Jacob Artist) and Wade "Unique" Adams (Alex Newell) perform "Sgt. Pepper's Lonely Hearts Club Band". Afterwards, Sue announces Tina and Stoner Brett (Ryan Heinke) as prom queen and prom king. On Bree's command, Dottie reluctantly drops a bucket of red slushie on Tina while she's on stage in the style of Carrie,^[1] and she exits in tears. New Directions follows her to the choir room, where they sing "Hey Jude" and encourage Tina to face the crowd and go back. She does so, receiving her much-awaited standing ovation.

Rachel is surprised at the diner by Mr. Campion (Peter Facinelli), the Funny Girl director, who tells her she has been cast as Fanny Brice. In Lima, cheerleading coach Roz Washington (NeNe Leakes) informs Sue that Bree is behind the prank and demands that she is punished. Sue instead promotes Bree to captain of the Cheerios and encourages her to torment New Directions as much as she can, in order to toughen them up in preparations for Nationals. Rachel, Kurt, Santana, and Dani perform "Let It Be" in celebration of Rachel's achievements, while New Directions does the same song in honor of Tina.
