Supernatural season 15 episode 20 is coming within a few weeks on The CW, with the title "Carry On." This episode is the final one for the entire show, which means we're going to see more personal stores. The series finale is all about the Winchester brothers, as well as the world they've built around them.

Rather than focusing on the mythology-based conflicts, Supernatural season 15 episode 20 will be more dramatic and emotional. However, The CW is keeping things under warp about the story at the moment. In fact, the synopsis didn't tease what's coming to Dean (Jensen Ackles) and Sam (Jared Padalecki).

The synopsis only notes that the longest sci-fi series in the United States is coming to an end after running for 15 years. The beloved Impala, Baby, would be on its finale ride for hunting things and saving people. Robert Singer directed the episode and written by Andrew Dabb.

The final season has seen Dean and Sam fighting against Chuck/God (Rob Benedict). This particular storyline will be wrapped in the penultimate episode. After that, Supernatural season 15 episode 20 proceeds to bring more heartfelt and personal stories.

Meanwhile, Ackles discussed some of the changes in the episode due to the pandemic. While the original plan hasn't been altered, the real-life health crisis limits the guest stars set to appear. The actor told Glamour that some familiar faces were set to return what that won't happen now.

Supernatural season 15 episode 20 is planning to bring back notable names that appeared in the past, but they weren't able to do that due to the global health crisis. Ackles said this particular part got nixed and filtered the guest stars into a montage, instead.

Before the series finale airs, there would be a retrospective special featuring the significant people in the show throughout its run. The interview includes series stars Ackles, Padalecki, Alexander Calvert, Misha Collins, along with creator Eric Kripke and executive producers Robert Singer and Andrew Dabb.

Two more episodes are coming before the series finale airs. In episode 18, titled "Despair," the Winchesters will be working with Castiel (Collins) and Jack (Calvert) to fight for the good of the common goal. They'll try to make sure that their plan would be successful.

The story will, then, be carried out through the penultimate, titled "Inherit the Earth." The battle against God continues and everything is on the line now. A familiar face will show up to help Dean, Sam, and others to join the fight.

Supernatural season 15 episode 20 is coming on Thursday, Nov. 19, on The CW.
