supernatural season 8 sam d 'Supernatural' Season 8 promo: Sam and Dean hug it out and set out on a new missionRule No. 2398 of being a Winchester: Hugs are totally allowed when someone returns from the dead. We just got our hands on the brand new “Supernatural” Season 8 promo video — a Zap2it first look — and we’re glad to see that the Winchesters are still following the rules.

The promo reveals the reunion of Sam (Jared Padalecki) and Dean (Jensen Ackles), after Dean’s year in Purgatory, which doesn’t exactly look like a cake walk in the brief flashes we see here. There’s even a mysterious, ominous image of Castiel (Misha Collins) looking forlorn and worse for wear.

Since Sam had no idea where Dean vanished to — and no one to contact for help — he’s done his best to move on over the course of the year, falling for a new love and attempting to settle into a normal life.

When Dean returns, though, the boys are reunited with Kevin (Osric Chau) and Crowley (Mark A. Sheppard), and that’s where things really get interesting. Throughout history, demons have been leaking out of hell, wreaking havoc on innocent people and waging war with angels. But what if the gates of Hell — which, incidentally, are rumored to be located at Stull Cemetery in the Winchesters’ hometown of Lawrence, KS — could be closed forever?

The promo reveals the major arc of the season, which involves the Winchesters hunting down the key to shutting those gates. If they’re successful, they’ll banish all demons from the face of the earth and lock them away forever. Of course, Crowley and his cohorts aren’t going to make it easy.

There’s also the question of whether Sam is interested in giving up the mundane, but safe routine that he’s established over the course of their year apart. Can he reconcile his dedication to the cause and his loyalty to his brother with the potential chance at a happy, comfortable life?

We probably don’t have to remind you, but just in case: Wednesday, October 3, 9 p.m., on The CW. Don’t miss it.
