Warning: Major Spoilers For 1923 BelowThe first episode of 1923 already revealed which main character will live to the end. 1923 is a show that shouldn't exist, as it was originally intended to be the second season of Yellowstone prequel 1883. Some confusion among executives at Paramount led them to greenlight 1883 season 2 – seemingly unaware that most of the cast were dead by the finale. Yellowstone creator Taylor Sheridan isn't one to waste a healthy budget though, so he set to work on the next big chapter in the Dutton clan's bloody history.
