Supernatural already has at least one easy way to return for another season without retconning the original ending. Centering on brothers Sam (Jared Padalecki) and Dean (Jensen Ackles) Winchester as they travel the country hunting monsters, Supernatural developed a passionate fan base who continue to support the show and its cast. Supernatural ran for an impressive fifteen seasons, finally coming to an end in 2020 with a definitive, if divisive, conclusion. Almost immediately after Supernatural's controversial series finale, fans began speculating about whether the show could ever return.
