Dean Winchester will get a chance to live out his boyhood fantasy – dressing up as a cowboy – in the upcoming episode of Supernatural season 13.

Episode 6 is titled, Tombstone, which will air this Thursday (16 November) at 8pm EST on The CW Network. In the episode, Jack will be reunited with Castiel as the hunters set out to investigate a Western outlaw.

The official synopsis of the chapter reads as follows:

Castiel (Misha Collins) is reunited with Jack (Alexander Calvert) and together with Sam (Jared Padalecki) and Dean (Jensen Ackles), they head to a sleepy old western town to investigate a murder. Dean gets to live out his boyhood fantasy when he comes face to face with a famous, gun-slinging outlaw.

A promo for the episode features Dean wearing a cowboy hat and boots with Castiel. The Winchester brother looks at an old photo of a Western outlaw and calls him "one of the greatest gunfighters ever". The entire gang, including Jack, will investigate the murder as Dean says, "He [the outlaw] died in 1886, which makes this a little weird."

The scene changes to a shot inside the car, wherein Dean tells Castiel, who returned from dead in episode 5, "Good to have you back." The promo ends with Jack asking Castiel, "Dean really loves cowboys," to which the angel replies, "Yes he does."

Actor Jensen Ackles (who plays Dean) spoke to Den Of Geek about Castiel's return and it changes things for his character. He explained, "At the end of last season and the beginning of this season we do see that Dean has just like given up, so to speak. So 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."

"Because if he was written off and Mom was written off, maybe there's a few other people that shouldn't have been written off. And we figure that out as the series continues to move on," Ackles added.

The mystery of how Castiel returned and where he was all this time will not bother Dean. "Dean's a little less questioning and more accepting of 'I don't care how it happened, we got our buddy back'," the 39-year-old actor told the website.
