Emma knows that something isn’t right about Storybrook, even if she doesn’t believe in the curse. So I don’t think shes going to leave. If she does leave, then Graham’s death would have been for nothing.
I really hope Regina doesn’t die or something. Maleficent is cool and all, but she has no connection to Snow White and Prince Charming, and therefore, Emma. Emma is the savior, and the whole story is about hope and her beating the curse. Where would the story go if Emma did defeat the curse this season? The characters all have to find their happiness, and I like the idea of them going back to fairytale land, but not just yet. Theres still so many stories left to tell. Rumpelstiltskin said that it was “the curse to end all curses”, so its going to be more complicated then Regina dieing, or Emma finding true love.
Regina will do anything to keep Mary Margret and David seperated. So I think thats why shes being so friendly to David. He probably doesn’t have many friends since he cheated on his wife and people think he could be a murderer. Why did he go to Regina for advice? Maybe because he sees her as a friend, or as someone who will listen and isn’t afraid of him.
