Plot summary
Ariel returns to Storybrooke and asks Hook to help her find Prince Eric, who never returned to the town when the new curse was cast. Emma agrees to let Regina teach her how to use magic so that she can help defeat Zelena, and Mary Margaret and David try to prove that they can be just as much fun as Hook is with Henry. Meanwhile, in the Enchanted Forest during the past year, an angry Ariel confronts Hook over her missing Prince Eric, who she assumes was kidnapped and possibly killed by the pirate. But when Hook confesses that the Jolly Roger has been stolen, Ariel unknowingly provides him with a clue as to who the other pirate is, and Hook with Ariel go off in search of his ship.
