What i think is that when Dean and Sam successfully close the gates of hell and Castiel and Metatron close the stairway to heaven, a davea should be born. And the davea helps the Winchester boys track down and kill Abbadon. And then the davea goes berserk and turns on Sam and Dean and now the they have to kill the davea.

That's my opinion
