It's finally the endgame, and everyone is ready to watch the finale of the "Supernatural" series. Yes, it's time to say goodbye to the Winchester brothers Sam (Jared Padalecki) and Dean (Jensen Ackles) forever as the CW drama reaches its climax after 15 seasons.

The "Supernatural" series finale will be preceded by a one-hour special looking back at the fantasy series and featuring interviews with cast and crew. And the finale itself is titled "Carry On," which is supposedly derived from the show's unofficial theme song, "Carry On Wayward Son" by Kansas.

In the series finale, Sam and Dean embark on a final journey to save people and hunt demons. Co-showrunner Andrew Dove told Entertainment Weekly, "It's a little bit more of an old-school episode."

In the final episode, the Winchesters confront Chuck (Rob Benedict) and witness Jack (Alexander) become a new god. Co-showrunner Robert Singer, who directed the finale, said, "It's a very emotional episode. It's a very personal story about the boys. The season mythology really ends with [episode] 19, but this is a little coda to that."
