When Regina split herself in an attempt to eliminate her evil half, she unwittingly released the Evil Queen. Now the Evil Queen is back and ready to leave a trail of destruction in her wake.

Emma learns a life-altering secret that could have serious consequences for her family and loved ones. While the heroes grapple with what Emma is confronting, Henry welcomes the new arrivals from the Land of Untold Stories by pledging to help them complete their tales.
