The first promo for Supernatural season 10 shows Demon Dean letting loose.

Watch the video below, as The CW teases Supernatural season 10 as the year of the Deanmon:

In this promo, we see Sam reminiscing about better times with his brother before he turns to doing some questionable things in his search for Dean. The brothers eventually reunite, and Demon Dean is channeling Jack Nicholson in The Shining as he stalks Sam through the Men of Letters bunker.

Meanwhile, Crowley tries to convince Dean to join him — but Dean clearly has his own agenda, and Crowley may be questioning whether helping Dean resurrect as a demon was the best call after all.

As for Castiel, he shares a brief phone call with Sam about Dean before running into trouble of his own as he deals with his fading grace.

But the best part of the promo is possibly the end, which has a hilarious snippet of Dean doing karaoke.

Excited? We definitely are!

As a refresher, the official synopsis for Supernatural season 10 reads:

“Season 10 begins with Sam’s frantic search for his missing brother, who is gone without a trace. The road to recovering the wayward Dean takes Sam down dark paths, with consequences that will shake the boys to their core. Meanwhile, Castiel has to pick up the pieces in the aftermath of Metatron’s campaign. With his grace failing and rogue angels still on the loose, Cass will face the ticking clock of his own mortality as all-new threats emerge to once again push all of our heroes to their limits.”

We also have a poster for season 10 and some photos from the season 10 premiere.

Supernatural season 10 premieres Tuesday, October 7 at 9:00 p.m. ET on The CW.
