care about anything enough to take my own life. Not you, your brother -- not even the world. But I believe in prophecy. I believe in magic. And I'm here and you' re here and everything we need to end this right is in our hands. I know this in my bones -- it has to be this way. Do it! Kill me, Samuel! I know we've gotten quite fond of each other, haven't we? But will you let the world die, let your brother die, just so I can live?
03 The Rupture]]
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. Following Rowena's death, Sam inherited her magical stash, as it's suggested that she intended.
When the Winchesters and Castiel returned to Hell in search of [[Michael]], they discovered that Rowena's [[soul]] took up the empty position of Queen of Hell. Retaining her old personality, Rowena aided the Winchesters once again and even urged Dean and Castiel to mend their relationship.
===[[15.08 Our Father, Who Aren't in Heaven]]===
The Winchesters and [[Castiel]] use a spell from one of [[Rowena's Spellbooks]] to enter [[Hell]] in search of [[Michael]]. As the three fight with [[demons]], they are shocked when Rowena interrupts them. Rowena explains that following her death, she was able to seize control of Hell for herself and has now become the new Queen of Hell. Though she knows Michael may not be in Hell anymore, Rowena directs her demons to search for the [[archangel]] and
reassures Sam that he did the right thing in killing her. Noticing tension between Dean and Castiel, Rowena, noting her own long list of regrets from life, urges the two to make amends. However, a demon brings word that Michael is no longer in Hell , forcing the Winchesters and Castiel to leave empty-handed.
