Here's everything viewers can expect from Supernatural season 15. After premiering in 2005, a passionate and dedicated fan following has helped drive Supernatural to an impressive, record-breaking number of seasons. Unfortunately, all things must come to an end, and it has now been confirmed that the forthcoming Supernatural season 15 will be the show's final run.

The announcement was made by Supernatural's central acting trio of Jensen Ackles, Jared Padalecki and Misha Collins, who have since elaborated on the situation, claiming that the decision to end Supernatural was a mutual one between show and network, rather than due to forced cancellation or issues tying the cast down to new contracts.

The most recent season of Supernatural wrapped up the arc featuring the alternate, apocalypse version of the archangel Michael and continued the story of Jack, the half-human son of Lucifer who has been taken in by the Winchester family and Castiel. However, with Supernatural season 15 looming ever-closer, what can the fandom expect from Sam and Dean's last hunt?

Supernatural season 15 premieres on Thursday, October 10. It has also been confirmed that, just like the previous season, Supernatural's last run will consist of 20 episodes, slightly shorter than the usual 22 or 23 episode seasons, but still leaving plenty of time to wrap everything up.

What Will Supernatural Season 15's Story Be?

Thanks to the cliffhanger ending that had fans on the edge of their seats during Supernatural's recent season 14 finale, there are quite a few pieces in place ahead of the final season, giving a fair indication of where Sam and Dean's tale will head next. The conclusion to Supernatural season 14 saw God raise the dead and fling open the gates of hell, meaning all the souls the Winchester brothers spent years fighting have now been released upon the Earth once again.

The outset of Supernatural season 15 will likely deal with the immediate aftermath of this apocalyptic situation, and there will be plenty of opportunities for some fan-favorite villains from Supernatural's past to make a final appearance before the show bows out for good. Once Sam and Dean have finished cleaning up God's mess and stopping the end of the world (again), their attentions will almost certainly turn to the Big Man himself, who has become disillusioned with mankind and seeks only to amuse himself with their misery.

Luckily, Sam and Dean won't be alone in their crusade against the Lord, as the finale also suggested that Death was none too happy with God for ruining centuries of hard reaper work. She also appeared to have an ally in the shadow-type being that exists as part of the Empty.

While no new roles have been confirmed for Supernatural season 15, recurring cast members Lisa Berry (Billie/Death) and Rob Benedict (God) are likely to have major roles and could be bumped up to season regulars alongside the usual suspects. Additionally, the fact that the residents of hell are now roaming free could allow for any number of returning faces including Jake Abel (Adam Winchester/Michael) and Lauren Cohan (Bela Talbot).
