"Supernatural" Season 9 introduced Cain, the Father of Murder, and his Mark in Episode 11 titled "First Born" and it got transferred on Dean Winchester (Jensen Ackles). Now that the Mark of Cain is doing something to Dean's behavior, will Cain return to help? Actor Tim Omundson teased the fans about it on Twitter.

According to the Enstars report, Tim Omundson confirmed that making another appearance in the CW TV series is possible even though he works on ABC's "Galavant." One fan tweeted about it and the 44-year-old actor responded.

Twitter account @RozeSPN posted that Tim Omundson can still come back as the badass character Cain even the actor is on another show. "That's the Plan!" Omundson responded on Tuesday, May 13, through his Twitter account @Omundson.

In the released promo videos for the Season 9 finale episode, Dean can be seen out of control because of the Mark. Speculations suggest that Cain will return to help Dean in controlling the Mark or taking it back.

The first promo video for "Supernatural" Season 9, Episode 23 titled "Do You Believe in Miracles" show Dean Winchester expressing his desire to kill. "Drop the blade Dean!" Sam (Jared Padalecki) yelled at his brother in an attempt to calm him down and stop his killing spree.

Crowley (Mark Sheppard) makes an appearance and explains to Dean what the Mark of Cain does to him. "The more you kill, the better you feel. The less you kill, the less better you feel," Crowley stated.

The second promo video released teased about Sam and Castiel's decision to lock up Dean in the Men of Letters bunker because of the Mark of Cain effects. In the previous episode, Gadreel (Tahmoh Penikett) decided to switch sides and join Team Free Will in taking down Metatron (Curtis Armstrong) but Dean slashed the angel across the chest with the "First Blade."

"Something is wrong with you Dean," Sam told his brother. Meanwhile, Dean is not happy getting locked up because he is confident that the Mark of Cain and the First Blade will give them the shot of taking down their enemy.

“@RozeSPN: Even w/ another show, Tim can still come back as #Cain - he is 2 badass 2 replace. @CrossroadsSPN #Supernatural” Thats the Plan!
