Back in May, the finale of Supernatural’s eighth season drastically redefined the landscape of the show. The King of Hell revealed his softer side, Castiel lost his angel essence, and for the first time we saw the Winchester brothers choose themselves over the mission. As a result we witnessed the angels fall from the heavens, so for season nine get ready to watch Sam and Dean deal with the consequences of that choice as they face a world full of suddenly homeless angels, each with an agenda all their own.
