While Emma, Mary Margaret, David, Regina and Hook continue their search for Henry in Neverland, Peter Pan appears before a startled Emma and offers her a map that will reveal her son’s whereabouts. But the only way to make the map appear is for Emma to stop denying who she really is and come to grips with her true feelings about her identity – and Mr. Gold receives some unexpected advice from a friend that could lead him to understand his life’s journey while in Neverland.

Meanwhile, in Fairy Tale Land during the past year, an angry Ariel confronts Hook over her missing Prince Eric, who she assumes was kidnapped and possibly killed by the swarthy pirate.
