History[edit | edit source]
After the disappearance of Lucifer, Sierra is in Crowley's former lair with several other demons as they argue about what to do. Suddenly, the Prince of Hell Asmodeus arrives and announces that he is in charge until Lucifer returns. Asmodeus calls forward Drexel, Harrington and Sierra before smiting the rest of the demons in the room. Sierra later watches as Asmodeus explains to Drexel about his attempt to release the Shedim.
While Asmodeus takes Jack to release the Shedim, he leaves Harrington and Sierra to kill the Winchesters and Donatello Redfield. As Dean goes to grab his things from his room, Sierra ambushes him from behind with a knife. Sensing Sierra behind him, Dean dodges Sierra's first strike and fights back. Though Dean briefly pins Sierra down, Sierra effortlessly breaks his hold and slams Dean around the room despite Dean's best efforts. Advancing on Dean with his knife, Sierra is stabbed through the heart from behind by Sam with an angel blade, killing Sierra.
