However, Dean and Crowley are completely unprepared when they find out who has the blade - Cain (guest star Omundson), the first son. Meanwhile, Sam is back at the bunker with Castiel (Misha Collins) who notices there is some leftover grace inside Sam. If they can extract it, they can use the grace to track Gadreel. The only problem is the procedure may do permanent damage to Sam.
