Supernatural season 15 is coming to an end with only one episode left. The series has been running on the CW for 15 years and it will now see the final journey of the Winchester brothers, Dean (Jensen Ackles) and Sam (Jared Padalecki). Fans are excited to see what the series finale has stored for them.

May have been wondering how the Winchesters' story concludes, with some speculating a "common ending"; either they're both dead or both alive. Writer and co-showrunner Andrew Dabb answered this, telling TVLine that Supernatural season 15 ends with Dean and Sam ending the journey together.

A lot of characters have come and gone throughout the series run, but the Winchesters have always been at the core of the story. Dabb explained that Dean and Sam started the journey together, so it'll only make sense that they're ending the journey together.

The series begins by telling the story of the Winchesters, and it's going to end with them. Dabb added that the final episode will answer some of the questions, including whether they'll end up in the same place, in the same way, and on the same page.

While Supernatural season 15 focused on a lot of conflict and chaos, the final episode will bring a personal story about Dean and Sam and the family they've built around them. In a separate interview with Entertainment Weekly, Dabb revealed that the series finale is more of an "old-school" feel.

The co-showrunner said that the final episode is going to be different. Instead of featuring mythology-focused, the series finale will become a lot more "old-school." Dabb confirmed that episode 20 will focus more on the journey of the characters.

He is also optimistic that fans feel satisfied with the ending as it "feels like a fitting end to the show". Fans can expect more dramatic stories and emotional moments within this episode. Dabb said that they're happy with how Supernatural season 15 is concluding and hoping that the fans feel the same way, as well.

The title of the series finale is "Carry On," which will honor the legacy of the Winchesters and other characters throughout their 15-year journey. The synopsis didn't provide much detail, though it noted the beloved Impala, Baby, will be on its final ride for hunting things and saving people.

But, before this episode airs, there's going to be a special episode, "Supernatural: The Long Road," featuring familiar faces. Some of them include lead stars, Ackles and Padalecki, alongside other cast members Misha Collins (Castiel) and Alexander Calvert (Jack).

Supernatural season 15 fill drop its final episode on Thursday, Nov. 19, on The CW.
