Changes

Nearly a year later, Jervis and another demon are employed by [[Lucifer]] to clean up his burned-out [[vessel]]s. Now completely loyal to Lucifer, both demons openly mock Crowley's plans to kill Lucifer and reclaim the throne of Hell. Enraged by their audacity, Crowley kills Jervis and the other demon with an [[angel blade]].<ref name="twelve01">[[12.01 Keep Calm and Carry On]]</ref>

===[[Barthamus]]===

A powerful [[Crossroads Demon]] that calls himself "the Crossroads Demon" following [[Crowley]]'s ascension to King of Hell. Dissatisfied with [[Asmodeus]]' rule of Hell, Barthamus steals a [[Nephilim]] tracking spell and offers to it to Sam and Dean in exchange for them stealing back his personal property, revealed to be Barthamus' human bones, from [[Luther Shrike]]. The Winchesters, [[Alice]] and [[Grab]] steal the bones, but Grab is killed by Luther in the process. When confronted, Luther reveals that he had made a deal with Barthamus centuries before to save his dying son's life, only to have Barthamus let him later die anyway. Disgusted by Barthamus' actions and his subsequent murder of Luther, the Winchesters refuse to complete their deal. Barthamus is killed when Alice burns his human bones, but the fire of the demon's destruction also destroys the Nephilim tracking spell.<ref name="thirteen08" />
