Cain could come back, remeber that we don t see Dean killing him , we don t see any light like we did with Abaddon and the boys never talk about that. Dean could set him into pieces like he did with Abaddon and Rowena spell could take bout marks Dean and Cain to release the Darkness. What i m trying to say is that we don t know from sure that Cain is dead.
