Ethan changes his piece for Showcase after criticism from his father, adding extra dancers (including Grace), angering Abigail. Christian's street-smart friend Kaylah arrives at the academy, looking for help from Christian (who she calls "Cheds") for her Showcase routine, alienating Tara, who realizes that she is in love with Christian and had been wanting to tell him so. Kat, who has also been told by her parents that her father wants to travel to Berlin to choreograph The Firebird with her mother as the principal dancer, alters Sammy and Ben's "steampunk" tap-dancing entry into a more modern three-person dance piece with herself as a burlesque ballerina being fought for by the two guys, and is offered an opportunity by a talent agent. Kaylah is overcome by last-minute nerves and Tara helps talk her into taking the stage, for which Christian is thankful and unknowingly alleviates her earlier uneasiness by telling her he loves her first. Abigail then closes the Showcase with Ethan's originally-intended solo performance for her to a new piece of music, "The Last Day on Earth".

The second years are assigned a dance project. Ben invites Kat to join his and Sammy's flash mob to impress her. Tara finds a picture of Christian and his mother on his bulletin board and unfolds it to reveal Christian's father. Tara questions him about his father but Christian refuses to talk about it. Grace makes things awkward between Abigail and Ethan when she says they obviously are dating each other, making Abigail tense and amusing Ethan. Tara and Christian, criticized by Miss Raine for skipping class, make their dance project a duet but still join Ben and Sammy's flash mob. Grace and Abigail also participate in the flash mob with Ethan as the cameraman. Sammy informs Ben that their planned flash mob show on the ferry is not possible due to the workers being on strike; Ben then decides to hold it on the train. Afterwards, Grace makes it known to Ethan that she in fact likes him before kissing him in sight of Abigail. This crosses into Tara and Christian's argument over Tara researching his father's whereabouts. In anger, Christian breaks up with Tara.
