Following the heroes' escape back to Storybrooke, Hook teamed up with the deceased King Arthur to locate the storybook so they could tell Emma how to defeat Hades. They went to find Cruella at the diner, where she reacted with disdain towards seeing Hook, but she coyly regarded Arthur with keen interest because of his good looks. When questioned about the haunting booth, Cruella admitted she destroyed it for good, since she didn't want anyone moving on if it meant she had to be stuck in the Underworld, too. Hook then pressed her about the book's whereabouts, which Cruella was surprisingly forthcoming about. She knew they would eventually figure out the truth even if she lied, and then told them that she put the book in the River of Souls. Cruella was later dethroned by Arthur who then ruled the Underworld for fifty years as she became a depressed and bitter woman who drank in the local bar with Sir Mordred.
