Why does he think it's a good idea to let the devil himself out of his cage? And let him inhabit your body? Castial isn't smart sometimes but thinking it's worth it to let the devil out so he MIGHT be able to destroy the darkness (Amara/God's Sister) I don't think it's worth it
And while Cas/Lucifer is plotting to find artifacts touched by god Sam and Dean are going ape at the wrestling watching their child hood wrestling hero and Dean got snubbed for the guy's glove and Sam is just like "Better luck next time buddy" I died
