In a desperate attempt to escape [[Michael's Monsters]], Sam calls upon the [[
Reaper]] [[Jessica (Reaper)|Jessica]] who Billie had following the Winchesters around. However, the Reaper [[Violet]] appears instead and reveals that Billie now has her Reapers following them around in shifts. Sam attempts to convince Violet to teleport the group to safety, but she refuses due to Billie's rules. Despite this, Sam, [[Castiel]], [[Jack Kline|Jack]] and [[Michael (Apocalypse World)|Michael]] are suddenly teleported to [[the Bunker]].
Later, as Dean recuperates in his room, Billie appears to him. Having heard the story of the others' inexplicable escape, Dean realizes that it was in fact Billie who was responsible despite it being against the rules. Billie admits to rescuing Sam and the others, stating that she "took a calculated risk" and asks Dean not to tell anyone. Billie chides Dean for ignoring her warnings about crossing universes which Dean feels was worth it to rescue Jack and [[Mary Winchester|their mother]]. Billie reminds Dean of his visit to [[Death's Reading Room]] and all of the notebooks showing the various ways he could die. Billie warns Dean that all of those notebooks have now changed: all but one fate has Michael escaping his prison in Dean's mind and using Dean's body to destroy the world. Billie hands Dean the notebook containing the one fate where Michael loses, shocking Dean at what it reveals must be done. Billie tells Dean that its up to him what he will do with the information and departs, leaving Dean with the notebook.
