Supernatural season 15 will be dropping its remaining episodes next month on The CW. This is the final installment so viewers should be prepared for big and intense stories leading to the series finale. We could see Sam Winchester and Dean Winchester facing more challenges along the way.

A lot of lives are in jeopardy in Supernatural season 15. There is a chance that some of the characters may not make it out alive until the end. And since this is the series finale, some key parts to the past might be explored to understand the things that are happening in the present and future.

The latest trailer teased that one more flashback episode is coming before the series wraps up its story. This is a chance to learn more about Sam (Jared Padalecki) and Dean's (Jensen Ackles) history and what they've been through before.

While the series has explored some of the things they encountered in the past, there could be something more about them that weren't shown yet. The final installment could dive deeper into some of these untold events, as well as their experiences viewers didn't know beforehand.

Supernatural season 15 could go into different directions, given that the show tends to bring unexpected twists and turns. Also, there is a question what the world would look like without God (Rob Benedict) and whether or not there's a chance to defeat hi,

Moreover, there's a concern about what's going to happen with Castiel (Misha Collins) moving forward. The remaining episodes are going to be dramatic and intense at the same time. The series finale needs to cover a lot of stories and ties some of the loose ends hanging since the beginning.

Since Supernatural season 15 will include one more flashback story, we could see some past cast members appearing at some point. This is a chance to honor the series, as well as those who have been part of the show throughout its run.

Meanwhile, the series was one of the shows impacted by the global health crisis. Ackles revealed that some of the stories planned before have been changed to accommodate the pandemic. Some of these include reducing group scenes and people on set to ensure the safety of cast and crew.

The good thing is that some of the remaining episodes have been filmed before the health crisis hits. A previous report from Deadline noted that the series finale was filming episodes 19 and 20. The goal is to wrap things up in the coming weeks, with the two-hour finale event airing on Thursday, Nov. 19.

Supernatural season 15 returns on Thursday, Oct. 8, on The CW.
