Big Sky gets a new sheriff! Get your first look at Jensen Ackles in his badge

There's a new sheriff in town.

On the Thursday night season finale of Big Sky, Jensen Ackles makes his debut as Beau Arlen, who steps in as a temporary sheriff to help out his buddy Sheriff Tubb (Patrick Gallagher) while Tubb is temporarily out of commission.

In the exclusive clip above, we get our first glimpse at Beau, who seems to immediately butt heads with Jenny (Katheryn Winnick). Of course, whether she's officially on the force or not, Jenny Hoyt has never responded well to authority meted out from law enforcement above her.

Despite Jenny's immediate dislike of him, Beau has already started making friends on the force, including getting tabs on where the best fishing spots are on in the area. In a character description previously released by ABC, Beau is described as a "confident and charming good ol' boy from Texas."

That works nicely for Supernatural alum Ackles, who is not only from Texas, but is now joining his former screen partner Jared Padelecki in portraying Texan law enforcement (Padelecki is currently starring on The CW's Walker, Texas Ranger reboot, now titled Walker).

ABC already announced that this will mark the start of an arc for Ackles in Big Sky country, as Beau will move from his season 2 finale guest star role to a series regular in a fully-fledged one season arc in the recently announced season 3.

Jenny's gut instincts are often right, so if she doesn't trust Beau initially, we probably shouldn't either. Perhaps Beau will feature in a new mystery in season 3, as this season's major storylines come to a head in the season 2 finale.

In addition to introducing Beau, "Catch a Few Fish" airing Thursday night, finds Jenny working to find Travis (Logan Marshall-Green) before he reaches a dangerous point of no return. Meanwhile, Cassie (Kylie Bunbury) changes the course of her quest for justice forever after receiving a startling surprise.

Big Sky was recently renewed for season 3 and upgraded Jamie-Lynn Sigler to series regular. It was also announced that country legend Reba McEntire will be joining season 3 as a series regular, as Sunny Brick, the matriarch of the Brick family, a "successful backcountry outfitter with a secret history of missing customers."
