After her death, Cruella ended up in the Underworld, a purgatory run by the deity Hades. While there, she met David's twin brother James; they quickly struck up a romantic relationship due to their similar personalities. When the heroes arrived with Gold to rescue the recently deceased Killian Jones (Colin O'Donoghue), Cruella was among the deceased of whom they came across. In hopes of returning to life, Cruella appealed to Henry, the new Author, to use the quill to bring her back to life. Later, she helped Regina locate the grave of her lost love Daniel, who had since moved on to a better place. Mistaking David for James, Cruella made a move on him, then informed him of the hostility James held toward his brother. Cruella and James then hatched a plan to get out the Underworld by delivering Hades the child of Robin Hood and Zelena. James pretended to be David and put a magic-neutralizing bracelet on Emma, while he and Cruella took the baby. They took Emma and Robin to the docks, planning to throw them into the River of Lost Souls, until David and Hook stopped them. David ended up throwing James into the River and Cruella ran off.
