On Friday, November 8, The CW announced that Supernatural will air on Mondays at 8 p.m. ET for the rest of its final season and will begin on March 16, and the last episode will air on Monday, May 18. The 15th and final season of Supernatural will consist of 20 episodes.
The decision to end Supernatural series wasn’t an easy one, according to Jensen Ackles. “It was months and months, if not years, of discussion between [Jared] and I, between the rest of the cast, between the crew, between our writers, between our producers, between the studio, between the network.”
“Nobody wanted to see this show fizzle out,” Ackles added. “I think that it was everyone wanting to do the biggest service to the show that we could by going out strong. It just seemed like the writing was kind of on the wall as to when that was happening. I think everybody kind of felt that it was coming soon. So it was just taking that leap of faith of going like, ‘Well, guys, let’s get out the paint and paint that finish line, and hold our heads high, because what we’ve accomplished is unlike any other.’”
Following Supernatural‘s final season premiere, Roswell, New Mexico’s second season will return on the same day at 9 p.m. ET. The CW also announced that Arrow will conclude with a two-hour special on Tuesday, January 28 – it will begin with a finale preview at 8 p.m. ET and will follow-up with the series finale at 9 p.m.
For shows returning to the network, The CW announced DC’s Legends of Tomorrow fifth season will start on Tuesday, January 21 at 9 p.m. ET, and the Riverdale spin-off Katy Keene (featuring Lucy Hale, Ashleigh Murry, Jonny Beauchamp and Julia Chan) will debut on Thursday, February 6 at 8 p.m. ET.
Additionally, the networked announced All American and Black Lightning finish their current seasons on Monday, March 9, with one after the other season finales.
