Changes

Dean, [[Tara]], and Crowley cast a location spell intended for the [[The First Blade]], but the spell sent them to the source of the blade's power; the Mark of Cain. Knowing that [[Dean]] wants [[the First Blade]] to kill [[Abaddon]], and after seeing him kill a number of [[demons]], [[Cain]] decides that Dean is "worthy" of carrying the Mark in order to wield the blade. Cain transfers the mark to Dean, where it appears on his right forearm. Cain warns Dean that carrying the mark will come at a great cost.
