Plot
Mal, Evie, Jay, and Carlos visit the Isle of the Lost to choose four new villain kids (VKs) to take to Auradon. They pick Dizzy, granddaughter of Lady Tremaine; Celia, daughter of Dr. Facilier; and Squeaky and Squirmy, the twin sons of Mr. Smee. As the older VKs return to Auradon, Hades attempts to break through the Isle's barrier, but Mal stops him.
The day the kids are to be picked up, Ben, Mal's boyfriend and the king of Auradon, proposes to her, and she accepts. Ben's ex-girlfriend Audrey seethes with jealousy, and her grandmother Queen Leah admonishes her for failing to secure the family legacy by marrying Ben. Unable to contain her jealousy, Audrey steals the Queen's crown and Maleficent's scepter from the museum, gaining magical powers and becoming a villain. Following the theft and Hades' escape attempt, Mal suggests that the best way to protect Auradon is to close the Isle's barrier permanently.
