Crowley asks Dean for help finding "The First Blade," the only blade that can kill Abbadon, but they are completely unprepared when they find out who has the blade -- Cain (guest star Timothy Omundson), the first son and the Father of Murder. Meanwhile, Sam is back at the bunker with Castiel, who notices there is some leftover grace inside Sam. If they can extract it, they can use the grace to track Gadreel. Check out the spoilers in the promotional photos for Supernatural Season 9 Episode 11, "First Born," airing January 21 on the CW.
