In 2018, Rowena began killing people and their [[reapers]] to get [[Death]]'s attention, as she blamed herself for Crowley's death and the path that her abandonment led him down in life. During this, the reaper [[Jessica]] reveals that in the book [[Death]] keeps on her, it is written that she will die by Sam Winchester's hand. While death refused to bring Crowley back, the experience ended with Rowena deciding that working for the greater good will be her redemption. She subsequently aided the Winchesters in their efforts to return to [[Apocalypse World]] and on occasions when they needed her expertise on a situation or case.
In 2019, after the release of the [[Hell Ghosts]] upon the world, Rowena chose to sacrifice herself to save the world by using her own body to cast all of the souls and demons back into Hell. At Rowena's request, and with great reluctance, Sam was indeed the one who fatally stabbed Rowena.
