It's really starting to sink in that Supernatural will come to an end after Season 15. Stars Jensen Ackles, Jared Padalecki, Misha Collins, and Alexander Calvert assembled in Hall H for their final appearance at San Diego Comic-Con, and it was an affair to remember.

In a completely unexpected reveal, Warner Bros. TV announced that someone in Hall H would walk away with a replica of the Winchesters' beloved Chevy Impala, a.k.a Baby. The lucky fans who got up to the mic to ask a question were entered into the impromptu contest, and Jared and Jensen pulled keys out of a raffle bag on stage. A stunned fan named Laura from Grants Pass, Oregon ended up walking away with what will probably be the best Comic-Con giveaway of all time!

That touching moment wrapped the panel, and with one final word from Jensen Ackles and Jared Padalecki — which naturally left them both in tears — the final Supernatural Comic-Con panel came to an end with a standing ovation from fans.

Padalecki, Ackles and Collins broke the news that the show would be ending via Twitter earlier this year. The upcoming 15th season will be the long-running CW show's last. Since then, the cast and crew have been flooding social media with sweet messages to the SPNFamily, as well as promises of "BIG!!! REAL BIG!!!" last ride, and what they'd like to see before it all comes to an end. Judging by the official trailer for the show's 15th and final season, the Winchesters are in for the fight of their lives.

Supernatural returns for Season 15 Thursday, Oct. 10 at 8/7c on The CW.
