User blog comment:FTWinchester/Season 9 concepts/@comment-2011995-20130911010510

I just had a brain storm - the story arc for this season; an alliance between angels, demons. I was thinking, the demons decide they don't like Abaddon, and naturally the angels are pissed at Metatron. They work on a plan to release both Michael and Lucifer in hopes that they will take back what is theirs. The Winchesters would be against it, but Castiel is leading angels on Earth, and the brothers realise this is probebly the only way they can beat Abaddon. At the end of the season, Michael and Lucifer are released, and when Abaddon is defeated and Metatron is put in his place, Michael has the same realization as Niaomi and decides to be the protectors of humanity angels were once were. Lucifer however decides the demons are disposable, and comes out with his plan B. Before anyone can stop him, he starts the first part of his plan, but opening the gates of purgatory.
