Yup, literal Deus Ex Machina.

The end of season 12 will be as follows (this is my guess, obviously): the English Men of Letters will be convinced that Sam and Dean aren't evil, but something else happens that screws everything up (maybe the Thules or something). Also, Lady Bevell will turn to Sam and Dean's side after observing them on a few jobs, or having them save her life, and she will become an outcast in the English Men of Letters (and part of the main characters), similarly to Castiel.
