Changes

As [[Fenrir Odensbane]] stumbles down an alley, drinking, Gabriel makes his presence known playing a kazoo to get Fenrir's attention. Stepping out from behind a dumpster, Gabriel declares his intent to face Fenrir "honorably" with not gimmicks or tricks. With a special wooden sword in hand, Gabriel and Fenrir begin their fight, when . Fenrir is able to wound Gabriel's arm, causing him to bleed, which is unusual for an archangel. Gabriel sees an opening and is able to fatal fatally stab Fenrir in the heart, killing him, but he gets maimed by Fenrir's claws in the process.

Gabriel retreated to Monte Carlo and partied with Fenrir, Sleipnir, and Narfi and a bunch of porn stars in their estate. One night, the trio restrained him and sold him to Asmodeus. For the past seven years, Asmodeus has been torturing him endlessly while Gabriel plots to one day exact revenge on them all. He also reveals that he intends to kill the god responsible for everything that happened; [[Loki]]. Gabriel explains that he saved Loki, who was bound in a cave somewhere in the Fjords with snake dripping venom in his eye. As repayment, Loki placed him into witness protection, thereby giving him his entire identity and teaching him to become the [[Trickster]]. In the meantime, Loki has been off the grid, but Gabriel knew he was hiding in Monte Carlo and thought that Loki would help him again after he faked his death. Dean believes that his time with Asmodeus never would have happened if Gabriel helped them fight Lucfier, but he reminds the Winchesters about how he told them about the [[Four_Horsemen_of_the_Apocalypse#The_Rings|Horsemen's Rings]] to slam Lucifer back in [[the Cage]]. Sam offers his and Dean's help to Gabriel if he agrees to help them. Gabriel accepts and explains that Loki is hiding in in the penthouse of the Ophidian Hotel. His plan is to kill Loki's sons in order before targeting Loki.

At the hotel, he tells the Winchesters that Sleipnir and Loki are his to kill while they take out the bodyguards. They take the elevator to the third floor and get in a shoot out with Sleipnir and his bodyguards. During the confusion, Dean takes the sword intended for Loki. After the gunfight ends, both the bodyguards are dead and Gabriel finishes off Sleipnir with his sword. Sam and Gabriel rush to the penthouse to catch up with Dean who is greeted by Loki. Loki explains that he sold Gabriel to Asmodeus for his role in the death of [[Odin]]. Despite knowing that Lucifer killed Odin, he wanted Gabriel punished as he gave the archangel his identity on the condition that he abandoned his family's volatile affairs forever, but he broke that promise and it cost his father his life. Dean tries to stab Loki, but he turns out to be an illusion to distract and attack Dean while the real Loki confronts Gabriel in the hallway. After Sam dispels the illusion, they rush to Gabriel to deliver the sword. Loki berates him for asking him for help again after inadvertently causing his father's death and questions whether or not he or his sons deserved to die for his cowardice. When the Winchesters arrive, Gabriel retrieves the sword and pins Loki to the wall. Loki tells Gabriel that he lives only for pleasure and stands for and will die for nothing, while Gabriel responds with "You first." and stabs Loki, killing him and completing his revenge.
