Promotional stills and a clip from Supernatural season 9, episode 11, “First Born,” introduce Psych favorite Tim Omundson as Cain.

After rescuing Sam from Gadreel’s clutches, Dean took responsibility for Kevin’s death and decided to hunt Gadreel for revenge alone. Sam let him go, though not before telling him that his guilt isn’t the real problem between them.

As Dean drove off in the Impala, Castiel stayed behind with Sam in order to continue healing the lingering damage from the trials. Read our recap for the January 14 episode, “Road Trip,” here.

The official synopsis for Supernatural season 9, episode 11 “First Born” reads:

TIM OMUNDSON (“PSYCH”) GUEST STARS AS CAIN — Looking to reclaim his place as King of Hell, Crowley (Mark Sheppard) asks Dean (Jensen Ackles) for help finding “The First Blade,” the only blade that can kill Abbadon (guest star Alaina Huffman). Knowing he owes Crowley a favor for helping Sam (Jared Padalecki), and also wanting Abaddon dead himself, Dean reluctantly agrees and the two set off on a road trip. However, Dean and Crowley are completely unprepared when they find out who has the blade — Cain (guest star Omundson), the first son. Meanwhile, Sam is back at the bunker with Castiel (Misha Collins) who notices there is some leftover grace inside Sam. If they can extract it, they can use the grace to track Gadreel. The only problem is the procedure may do permanent damage to Sam. John Badham directed the episode written by Robbie Thompson (911).

Upon Omundson’s casting, it was revealed that Cain is a retired demon who used to train the Knights of Hell. Also known as The Father of Murder, Cain quit his evil ways for love but is clearly game to cause trouble for the Winchesters.

Meanwhile, promotional stills depict Sam and Castiel in the bunker attempting to extract Gadreel’s leftover grace from Sam as well as Dean and Crowley confronting Omundson’s Cain.
