On the next episode of SUPERNATURAL on The CW titled "We Happy Few" - Sam (Jared Padalecki) and Dean (Jensen Ackles) face their biggest challenge yet. Rowena (Ruth Connell) makes her move. John Badham directed the episode written by Robert Berens and airing Wednesday, May 18th on The CW. Get a sneak peek below!

The thrilling and terrifying journey of the Winchester brothers continues as SUPERNATURAL enters its ninth season. Sam (Jared Padalecki) and Dean (Jensen Ackles) have spent their lives on the road, battling every kind of supernatural threat. Over the years, after dozens of bloody adventures, they have faced everything from the yellow-eyed demon that killed their mother to vampires, ghosts, shapeshifters, angels and fallen gods. They even came face to face with Lucifer and the Four Horsemen in averting the Apocalypse. With the help of allies — both human and supernatural — they’ve discovered that every threat they vanquish opens a new door for evil to enter in.

In the show’s eighth season, their supernatural hunting expedition led them directly into an age-old power struggle involving the King of Hell, legions of warrior angels and a series of divine trials to prove themselves worthy of sealing the Gates of Hell forever. With the help of their protector, the fallen angel Castiel (Misha Collins), Sam and Dean’s lifelong quest to rid the world of evil will take everything they’ve got. As dawn arrives after their endless struggle and sacrifice to defeat the world’s monsters, they know that, come nightfall, something otherworldly — something supernatural — will claw its way out of the shadows, demanding their attention.
