Janice Halliday, reeling from a breakup, joins him, and they dance together until Chuck pauses from a headache but then keeps going, delighting everyone. Afterwards, Chuck and Janice help Taylor pack up, and they split the money. Taylor proposes they become a traveling troupe, but Chuck and Janice decline and share a hug before parting.

Act I: I Contain Multitudes
As a child, Chuck loses his parents in a car accident and goes to live with his grandparents, Albie and Sarah. Sarah encourages his love for dancing, while Albie turns to alcohol and forbids Chuck from entering the house’s cupola, claiming he’s seen ghosts there. At school, Chuck’s teacher Ms. Richards explains to him that he “contains multitudes,” meaning his memories create a universe inside him. After Sarah dies, Chuck joins the dance club “Twirlers and Spinners,” becomes its best dancer, and teaches his classmates the moonwalk. He grows close to Cat McCoy, who invites him to dance at the Fall Fling. Despite Albie wanting him to become an accountant like him, Chuck chooses to dance at the event, earning cheers and sharing a kiss with Cat. He later dances alone outside, injuring his hand and leaving a scar. When Albie dies, teenage Chuck inherits the house and finally enters the cupola, where he sees a vision of himself dying, recognizing his scar. He dismisses the vision and vows to live fully, declaring, “I contain multitudes.”
