The promo video clip for upcoming "Supernatural" Season 9, Episode 11 titled "First Born" has been released but it does not really reveal the "Father of Murder" Cain (Tim Omundson). Instead, the sneak peek video shows angel Castiel (Misha Collins) not pleased eating a peanut butter and jelly sandwich while discussing his human experiences with Sam Winchester (Jared Padalecki) at the "Men of Letters" bunker.

"It's disgusting," Castiel tells Sam while making comparisons on the eating experience of an angel against human beings. Aside from the promo video, image stills of Castiel and Sam in the bunker were also leaked to show that the two will be working together to extract the remaining grace of angel Gadreel in Sam's body.

Meanwhile, Dean Winchester (Jensen Ackles) and Crowley (Mark Sheppard) team up to find the weapon that can kill rival Abaddon (Alaina Huffma) but the unlikely duo must go through Cain who holds "The First Blade." The brand new episode will introduce "Psych" actor Tim Omundson as Cain, the trainer of the "Knights of Hell" who gave up being evil for love.

The official episode synopsis in the Hypable report 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."

As for Sam Winchester's health condition after the angelic possession, Castiel noticed Gadreel's leftover grace is still inside his body. Castiel reveals the grace can still be extracted and used to track down the treacherous angel but the process may do permanent damage to Sam's body. Will Sam be able to get through this ordeal?

"Supernatural" Season 9 Episode 11 "First Born" is scheduled to air on Tuesday night, Jan. 21, at 9 p.m. ET on the CW network.
