I like the idea of General MGD, about Dean and Cas fighting old enemies on Purgatory while Sam works on freeing them.

It would also be a continuation of the Season 7 theme, which was taking away everything they had. First the Impala, then Bobby, and now the biggest thing they can lose: each other.
