The CW has released a preview clip for this week's episode of Supernatural, titled "Family Matters," in which Cas (Misha Collins) is called in to diagnose the soulless Sam (Jared Padalecki) and a distrusting Dean (Jensen Ackles) is convinced Grandpa Samuel (Mitch Pileggi) and the Campbell clan are up to no good. Here's the official synopsis:
Dean (Jensen Ackles) becomes suspicious of Samuel’s (guest star Mitch Pileggi) motives, but Sam isn’t sold on the idea that their grandfather is doing anything wrong. The brothers go along on a hunt with Samuel and the other Campbells, but things go terribly awry.
Check out the preview and promotional photos below. Supernatural airs Friday at 9 p.m. ET/PT on The CW.
