Supernatural season 15 episode 15 is coming next month on The CW, with the title "Gimme Shelter." This episode sees the return of Amara (Emily Swallow), who hasn't been in the series for quite some time now. The character was last seen in the early run of the current season.

Amara's arrival is one of the significant parts of Supernatural season 15 episode 15. Her relationship with God (Rob Benedict) is something that needed to be further addressed, along with the struggles Sam Winchester (Jared Padalecki) and Dean Winchester (Jensen Ackles) have been facing.

Based on the synopsis, the Winchester brothers go on a journey to search for Amara. However, the hunt for her won't be that easy. These two may encounter several setbacks along the way. Some unexpected events that could happen moving forward.

Amara will appear for one more episode after this one, as well. This means that we could see more of her down the road, and lot of stories are coming for this character. She could bring more chaos to Sam and Dean, give that she's known as The Darkness.

As for what else is coming in Supernatural season 15 episode 15, there's a significant story coming for Castiel (Misha Collins) and Jack (Alexander Calvert). These two will be working together to solve a case involving the members of a local church.

This episode would be an epic one, especially since we're nearing the series finale. One of the biggest storylines is getting some resolution in the God arc, something that should be answered before the show officially wraps up. Also, this could open more personal stories in the end.

It has been teased that the final episode of the series will bring more personal stories rather than mythology-based conflicts. Co-showrunner Andrew Dabb told TVLine that most mythology stories were wrapped up in the penultimate, while the finale would be an emotional one.

The story will focus more on Sam and Dean, and the family that they've been around them. We won't be seeing more fights in here. This will be a dramatic episode, honoring the Winchesters and others throughout their journey. After all, the series has been on the small screen for 15 years.

Supernatural season 15 episode 15 airs on Thursday, Oct. 15, on The CW. The episode is directed by Matt Cohen and written by Davy Perez.
