How Many Episodes Are In ‘Supernatural’ Season 15? Episode Count Revealed

The CW’s long-running dark fantasy series, “Supernatural,” which first began on the network’s predecessor, The WB, in 2005, is getting ready to say goodbye when its current season ends.

Season 15 of the drama premiered last Thursday, and the second episode airs tonight, but how many more “Supernatural” episodes will fans get to see after that until the story of the demon-hunting Winchester brothers — Sam (Jared Padalecki) and Dean (Jensen Ackles) — and angel Castiel (Misha Collins) comes to a close?

The final season of the CW show has an episode count of 20, which means fans still have 19 episodes left to enjoy, including tonight’s broadcast, which is titled “Raising Hell.”

According to the synopsis, episode 2 of Season 15, which was directed by Robert Singer and written by Brad Buckner and Eugenie Ross-Leming, sees “Sam, Dean and Castiel call on Rowena (guest star Ruth Connell) to help keep the evil souls at bay and get an unexpected assist from Ketch (guest star David Haydn-Jones).”

Of the decision to end the show after 15 seasons, Padalecki recently told Michael Rosenbaum on the “Smallville” alum’s “Inside of You” podcast that it was everyone’s choice.

“It was an agreement [with everyone to end the show]… This was sort of, ‘Hey, let’s go ahead and do what’s best for our family and the world and the show,” Padalecki said. “We had some pretty outrageous and outstanding support from CW and WB.

“Maybe it’s part of them just being kind to their actors so that we don’t freak out, like actors do, but I believe that if we wanted to go five, 10, 15 more years, they probably would’ve justified [it] because they know what we’ve sacrificed, how we’ve worked and how they worked. We always said, ‘When it’s time for the show to end, we’ll know.’ And that moment hit and we were like, ‘Okay, I think it’s time for the show to end.’”

“Supernatural” Season 15 episodes air on The CW on Thursdays at 8 p.m. EDT.
