Nyah swam with Harold under the sea, and promised him the eternity with her, if he'd leave his wife and would come with her during the next high tide. Mr. Roarke tried to warn Nyah away from Harold, reminding her their previous encounters, but Nyah felt too strongly about her love and ignored his warning.
