Preview Supernatural season 9, episode 21, “King of the Damned,” with the episode synopsis, promotional stills, and trailer.
Going into this week’s episode, the race to take down Abaddon has heated up. The Winchesters learned Abaddon is harvesting souls across the country to make a demon army loyal only to her, leaving soulless humans on the rampage.
Meanwhile, Dean came in contact with The First Blade. He found the combination of it and the Mark of Cain overwhelming, and only Sam was able to break through the blade-induced bloodlust. Crowley then double-crossed the Winchesters, stealing The First Blade and telling them he would only give it up when the brothers were ready to kill Abaddon.
And Metatron captured Castiel in the hope of pressing him to lead the rogue angels — and play the villain in Metatron’s story. After the Winchesters exchanged Gadreel, whom they had captured, for their friend, Castiel finally agreed to lead.
