While in prison, Jack is contacted by Henry Turner, the son of Will and Elizabeth, to seek his aid in finding the Trident of Poseidon. Remembering Elizabeth and Will from his previous misadventures, Jack agrees but not before expressing some hesitation. The next day, Sparrow is sentenced to be executed by guillotine (by Jack's accidental choosing), but is rescued by Henry and his crew. Aided by aspiring astronomer Carina, Jack and Henry attempt to locate the Trident of Poseidon, as both are in need of its power to break curses related to the sea. Barbossa releases the "Pearl" from its bottle, giving them a chance to outrun Salazar. Jack and Barbossa discuss the fact that Carina is in truth Barbossa's long-lost daughter, whom he had left at an orphanage in order to give her a chance for a better life. Jack attempts to use the secret to blackmail Barbossa, but fails.
