Based on a five-year-old promise, Supernatural season 16 could finally happen in 2025. After 327 episodes across fifteen seasons, Supernatural finally came to an end, breaking the hearts of many fans. Since then, a large portion of the fandom has longed for season 16, so they could return to the world and characters they love. The prequel, The Winchesters, helped fill the gap to a small degree, but it didn’t quite have the same impact. The timing was poor because fans didn’t have enough time to mourn the original show, so The Winchesters ended after a single season.
