Tumblr Rumor:"Cora and Hook will come to Storybrooke SOON, but they will disguise themselves as Emma and Snow. Cora will be Emma so she can get close to Henry and Hook will be Snow. Everyone in the town will think something is “up with them” but will think that it’s a side effect from having gone back and forth between worlds. Someway, maybe by slip of tongue or manerisums, Regina will figure out that Emma is actually Cora. Jump to what might be the winter break before Hiatus… Regina tries to confront CoraEmma and they get into a big fight. Henry ends up getting taken (maybe back to Fairy Tale Land) with Cora JUST AS the real Emma and Snow return. and that would be the final moments in the episode! After Hiatus and the show returns I THINK, With there being now TWO snows (because no one would know about Hook being the other Snow) the real snow and Emma are locked up where they have to prove that they are the real ones. Regina would be the only one who knows the truth and it will come down to Regina having to team up with Emma to go after Cora. Which will lead to another big show down between mother and daughter!
