I gave you what you wanted, what she had. It's not... perfect. The Underworld is a place of, uh... well, destruction. Despite my best intentions, things don't grow here. They decay. But it's our decay.

Hades to Zelena

"Our Decay" is the sixteenth episode of Season Five of ABC's Once Upon a Time. It was written by Tze Chun & Dana Horgan, and directed by Steve Pearlman. It is the one hundred and fourth episode of the series overall, and premiered on April 3, 2016.


Emma, Snow, David, Regina, Robin, Henry and Hook continue to search for a way to free everyone from the Underworld. At the mercy of Hades, Gold creates a portal to Storybrooke, which transports Belle, Zelena and Baby Hood to the Underworld. While Zelena and Regina get into a sibling squabble, Belle is reunited with Rumple only to learn some tremendously shocking news that will change her life forever. Meanwhile, Snow and David hopelessly attempt to send a message from the Underworld to their son, Neal. In flashbacks, Hades learns about Zelena's very special spell and pays her a visit in Oz with the intention of striking an alliance, but finds himself with more than just a partner in crime.[2]


This section is a detailed recap of this episode. There are major spoilers. Click to expand.

Several years ago, Zelena is celebrating the day she was abandoned by her mother Cora in the Land of Oz. Her flying monkeys bring back a Scarecrow, who she hopes she can use to create a time travel spell to change history by ensuring her mother does not abandon her. However, the Scarecrow is saved by Dorothy, who has come back to Oz using a pair of silver slippers.

In present-day Storybrooke, Belle tends to baby Neal at the convent when she sees Mother Superior. Another Mother Superior shows up, telling Belle that her double is an impostor. Zelena then reveals herself. She found a way to return from Oz in the hope of taking back her child. However, when she tries to leave the convent, a portal opens that sends Belle, Zelena, and the child to the Underworld.

In the Underworld, the clock hand ticks again, signifying that yet another soul had moved on. Hades reflects on the page depicting him with Zelena. Gold is trying to create a portal to bring Zelena's daughter to the Underworld so that Hades won't take his own child.

Meanwhile, Snow White and David Nolan discover that they can use a special phone to contact their son Neal. At the loft, Henry is showing Snow, David, Regina, Robin, Hook and Emma illustrated drawings that mysteriously appear to him. Zelena then surprises them. They believe Zelena may be dead but she explains that a portal brought her, her child and Belle to the Underworld.

At the same time, Belle surprises Gold at the shop who then comes clean about still being the Dark One and his reacquired powers, as well as her pregnancy. Gold tells Belle that she will have to choose whether or not she wants to be with him even though he will never change.

Back in the past, Zelena confronts the Munchkins who told Dorothy that Zelena was still alive. Hades appears and offers his assistance to capture the Scarecrow, only Zelena replies that she needs no help and vanishes. However, Zelena later reconsiders. Hades reveals that his power is limited to the Underworld unless he receives a kiss of true love.

Robin, Regina and Zelena catch up with Belle and return the baby to Zelena so she can feed her. However, Zelena was about deceive everyone by escaping with her daughter, only to have a change of heart and returns her baby upon learning that her magic isn't powerful enough in the Underworld to protect the baby by herself. She believesthat Hades brought her to the Underworld so that he can use her daughter to enact a time-travel spell.

Meanwhile, at the loft, everyone starts to believe that Zelena, even without her powers, can help them. Henry also shows them more drawings, including the story of baby Neal hearing his parents, indicating that Snow and David succeeded in getting the message to their son.

Back in Oz many years earlier, Hades brings Zelena to Dorothy's bicycle so that they can find the Scarecrow. Hades enchants it so it will bring the two to Dorothy and they find an attraction between them. They arrive and Zelena takes The Scarecrow's brain, but leaves Dorothy alive to prevent turning her into a martyr and to humiliate her. As Hades reveals his love for Zelena, but she believes that he is only manipulating her for true love's kiss and the time travel spell which he will use for his revenge against Zeus. Zelena demands that Hades leave Oz.

Outside in the street, Zelena later confronts Hades to tell him that she will never give him her baby. Hades later admits to having feelings for her, claiming that he was simply trying to summon her daughter to keep her safe, even going as far as creating an Underworld version of Storybrooke for them to share together. However, Zelena turns down Hades again. He finally tells her that if she ever changes her mind, he'll always be waiting for her "at home" in the Underworld.

  28. 28.0 28.1 Pandemonium. Web Gallery of Art. Retrieved on February 1, 2021. “In the 1820s Martin produced a series of paintings depicting scenes of disaster, set in infinite, visionary spaces and full of theatrical, nightmarish lighting effects. Their basic mood largely derived from the artist's familiarity with John Milton's epic poem Paradise Lost and with the biblical Apocalypse. The Pandemonium of 1841 goes back to a passage in the first book of Milton's Paradise Lost, in which "Pandemonium, the palace of Satan, rises suddenly built out of the deep." In a diagonal perspective characteristic of Martin, a gigantic building complex extends along the waterfront. This recalls fantastic reconstructions of cities of antiquity. Martin's Satan, whose invocatory figure stands on a rocky outcrop in the right foreground, has the look of an ancient Greek hero. Like Achilles outside Troy, he appears with shield and feathered helmet, but commanding an army not of besiegers but of demons and damned souls in their Cyclopean city.”
