ELSA IS COMING!
When Hook and Emma come back safely, they bring along Robin's wife that was supposed to be executed by Regina in the Enchanted Forest. What they didn't know was that the vase that Hook was looking at in the room that they were banished to was sucked into the portal along with Hook, Emma and Robin's supposed-to-be-dead wife. And in that vase was Elsa in a melted form. When she came through the portal, she formed into herself and destroyed the vase that she traveled in. Then BOOM! She just walks out and the screen goes dark. What has Elsa came to Storybrooke for? We will have to wait when Season 4 premiere in Fall 2014.
