With Robin Hood's wife, Marian, back in the picture, Regina wonders if her "happily ever after" with the former thief has been completely quashed; while on their honeymoon, Mr. Gold finds an intriguing object that makes him question whether or not he should officially give Belle control over the dagger that makes him The Dark One, and Hook is dismayed to discover that Emma seems to be avoiding him.

Emma arrives in Storybrooke with Henry and reunites with her friends and family, only to discover that no one remembers how they were transported back--or the past year they had spent back in Fairy Tale Land. But Emma is sure that someone in town is responsible for this new curse and teams up with Regina in an attempt to uncover their identity. Meanwhile, in Fairy Tale Land during the past year, Regina, with the aid of Robin Hood, attempts to break into her castle, which has been overtaken by the Wicked Witch.

With Mary Margaret in labor and due to give birth at any moment, the residents of Storybrooke go on high alert in an attempt to ensure that Zelena doesn't try to steal her newborn baby for use in her ultimate game plan to turn back time and change her destiny--while obliterating Regina's existence. Meanwhile, in the land of Oz of the past, Glinda tries to convince Zelena to fight her evil tendencies and join her and her sister witches as a protector of Oz. But the appearance of a young girl from Kansas could turn out to be her undoing.
