The CW has released the official poster for Supernatural season 8 as well as the synopsis for the fifth episode of the season, “Blood Brother.”

The poster is an exclusive from the official Supernatural Facebook page:

The poster gives us a good indication of who the major players in season 8 will be, with Sam and Dean in the forefront and Castiel and Crowley in the background.

Winchester Bros also has the episode synopsis for the season’s fifth episode, “Blood Brother,” which is written and directed by two fan favorites in Ben Edlund and Guy Bee, respectively:

BENNY CALLS DEAN FOR HELP — After Benny (Ty Olsson) gets brutally beat up by some vampires, he calls Dean (Jensen Ackles) for help. Dean abruptly packs up and tells a confused Sam (Jared Padalecki) that he’s taking a “personal day.” Benny confesses that he’s going after his Maker (guest star Patrick Stafford) so Dean offers to help, flashing back on the many times Benny helped him and Castiel (Misha Collins) in Purgatory. Meanwhile, Sam (Jared Padalecki) uses his solo time to reflect on the life he left behind with Amelia (guest star Liane Balaban). However, when things go bad for Dean and Benny, Dean calls Sam for help, which makes everything very complicated. Guy Bee directed the episode written by Ben Edlund.

It looks like the flashbacks will continue and that Sam will finally be finding out about Dean’s secret vampire friend, Benny. We’re looking forward to the inevitable confrontation, considering the parallels to previous storylines, including Sam secretly working with Ruby in season 4 and Dean killing Sam’s childhood friend Amy because she was a monster in season 7.
