The iconic gang is back together for the next episode of "Supernatural" season 13.

Titled "Tombstone," the episode will see the mysteriously-resurrected Castiel (Misha Collins) reunite with Jack (Alexander Calvert). Together with Sam (Jared Padalecki) and Dean (Jensen Ackles), they will head to a sleepy western town to investigate a murder.

Fortunately for Dean, they will meet a famous, gun-slinging outlaw, the ultimate gift for the man who has great dreams of being a cowboy. They might be out there for a mysterious case, but for Dean, it's the wild, wild west coming to life.

The set-up for the next episode promises to be a comedic relief from all the monsters and evil spirits they have been battling. The past season and a half has been particularly dark. Without Castiel, it was a lonely world indeed. His return also brings back the light side of the Winchester brothers that fans have come to miss. It will also be the first time that the four of them are going out on a haunt.

In an interview at the "Supernaturals" set, Ackles admitted that his character has all but lost hope in the beginning of season 13. "The return of Cass has ignited that fire again. He's got some hope and motivation to dig a little deeper and see what we can figure out," he told a group of reporters.

If the promo below is any indication, "Tombstone" will be an entertaining rollercoaster ride of horror, thrill, action, and a lot of comedy.

With Castiel now back in the real world, the Winchesters are more positive than ever that they will be able to save their mother from the alternate reality she is stuck in. However, there is still that issue of how Castiel was able to return. Dean is more accepting, but Sam, not so.
