Changes

Following the return of [[Eileen Leahy]] as a [[ghost]], Dean suggests creating another Soul Catcher and sends Sam to [[Rowena's Apartment ]] to find her stash, suggesting that Sam can make one as he was Rowena's protégé. With the help of Eileen, Sam finds Rowena's magical stash, including journals of her spellwork throughout her life, and he becomes emotional at the reminder of his dead friend. Among Rowena's journals, Sam finds a [[resurrection]] spell Rowena had been creating to bring [[Mary Winchester]] back, one that Sam realizes can be used to bring back Eileen. Sam is subsequently captured by the remaining two witches, who suggest that Rowena specifically excluded Sam from being harmed by the curse because she wanted him to inherit her magical stash once she was gone. Sam is later able to kill the [[Witch Mother]] with a spell Rowena taught him and use Rowena's resurrection spell to bring back Eileen.
