The Father of Murder is back on Supernatural.

Will Sam's Demon Side Resurface On 'Supernatural'? Jared Padalecki Teases Dormant Problem

Cain (Timothy Omundson) will make his highly anticipated return in "The Executioner's Song," and new photos indicate that the first blade will as well. Dean (Jensen Ackles), the Mark, the First Blade, and Cain will all be in the same room for the Feb. 17 episode, making for an explosive combination that can only end badly.

It's time for Dean to kill Cain, but the first demon will not go down without a fight, despite his previously professed desire to die. Even without the Mark, Cain appears to be far more powerful than a troubled Winchester (see video below).

"I've heard the story line and it's pretty wicked," Omundson told AfterBuzz TV before filming started in December, later assuring fans that "it's going to get pretty intense."

While Dean and Cain's battle plays out in a barn, "Executioner's Song" will also take viewers back to Crowley's (Mark Sheppard) lair. Thanks to a little deception, Rowena (Ruth Connell) and her son are closer than ever. The oft-absent Mum won't like it when her lad skips out on plans to consort with the Winchester brothers, however, and the scorned witch is bound to use a little magic to express her displeasure.
