Two weeks into his hiring, Dewey sneaks some of his students out of school to audition for a spot in the competition, while the rest of the class stay behind to maintain cover. When Freddy wanders off, Dewey retrieves him, but the group is rejected because the bill is full. After Summer tricks the staff into thinking that the students all have a terminal illness, the band is added to the bill. The next day, Mullins decides to check on Dewey's teaching progress, forcing Dewey to teach the actual material. Mullins explains that a parents' night will take place at the school the day before Battle of the Bands. Dewey and Mullins strike up a friendship over their shared enjoyment of music, particularly Stevie Nicks, and she laments to him about how her job as principal puts her under pressure by overzealous parents.
