Cut Content: In the promo for the episode, "Ruby Slippers", Hades says, "The gods don't like it when mortals play with their toys." This line is not in the final episode.
Goof: The drawing of Hades and Zelena that can be seen in one of the storybook pages Hades had Liam Jones rip off for him depicts Zelena with a different shade of green than the usual one. However, a different page was made for "Our Decay", with her skin properly painted emerald green.
For the previously on Once Upon a Time part of "Our Decay", the scene was edited to make her look greener in the drawing.
