Mr. Gold finds an unwilling test subject to see if a spell he has concocted will allow him to cross the border of Storybrooke - without losing his memory - and go in search of his son, Bae. Belle stumbles upon a vengeful Hook in the Storybrooke harbor whose main goal is to eradicate Rumplestiltskin, and Mary Margaret and David go house hunting in search of a bigger place to live. Meanwhile, in the fairytale land that was, Belle meets Mulan as the two set out to slay a fearsome beast called the Yaoguai, who has been ravaging the land.
