In flashback, Snow makes a wish that causes everyone to burst into song, infuriating the Evil Queen. In Storybrooke, this wish comes back into play as Emma and Hook prepare for their wedding, and the Black Fairy announces her plans.
Believing there isn’t room in Storybrooke for both her and Regina, the Evil Queen sets out to eliminate her other half. Hook, determined to make things work with Emma, turns to his old friend Captain Nemo for advice, but Gideon torpedoes the plan before he’s able to set things right.
The Evil Queen uses Aladdin’s lamp to make Emma’s wish of never being the Savior come true, sending Emma to an alternate reality of the Enchanted Forest; Regina and David both make bold moves in order to try to find Emma; Gold and Belle receive surprising news about their son.
