Pandora's Box is a magical box-like artifact and an item featured in the Once Upon a Time series. In Storybrooke, Pandora's Box is one of the numerous items Mr. Gold keeps locked up in his pawnshop. Previously, he enchanted the box's hiding spot that can only be triggered if and when the chipped cup is placed back into its saucer in the cupboard. After Mr. Gold goes to Neverland save Henry, he believes must die in order to defeat Peter Pan and decides to sacrifice himself, but many complications arise. Eventually, he and Regina form a plan to retrieve a box, which has enough evil stored inside it that Mr. Gold believes will be enough to defeat Pan. Regina strikes a deal with a mermaid, Ariel, to bring it back, but he can't tell her what the item is without Pan possibly finding out as well.
