Seller: Any word of whether Chuck will be back on Supernatural? I'm happy to see that the show is finally getting its groove back after Kripke jumped ship, but I still want to know if Chuck was God or not. They seem to have abandoned that storyline.
You're right, sorry. It has been dropped for now, from what I hear. No plans for a Chuck return. New show runner Sera Gamble told us, "We love Rob [Benedict] and never say never, but we haven't written a story for him yet."
