Snow White's glass coffin can be seen in the cave.
During the filming of the brief fight scene between Emma and Regina, Jennifer Morrison and Lana Parrilla both suffered bruises from the way they slammed each other into the walls.
The case that Mr. Gold opens to unveil Prince Charming's sword to Emma and Regina was a guitar case that the show's property master Bill Burd had owned. It was his idea to use the case as an in-show prop for storing the sword.
The title card features a cloud of magic, either the Dark Curse or the magic that has been brought by Mr. Gold. This is the first title card not to be accompanied by the usual opening music.
The title of this episode was announced by Adam Horowitz via his Twitter account on March 20, 2012.
