Walker has had quite the ride on Yellowstone this season. He was first introduced in the series' debut season and became a main character after being hired by John Dutton (Kevin Costner) at his ranch. In the beginning, he and Rip clashed because Walker wasn't interested in getting into fights or working hard. But he soon got the hang of it and started to work well with everyone.

During the third season, he found himself at the center of some of the show's biggest twists. First, he was banished from the Dutton Ranch by Kayce (Luke Grimes) for helping Jamie cover up a murder, and then he was discovered singing in a bar. He was supposed to be killed, but instead, Rip and Lloyd Pierce (Forrie J. Smith) spared his life.

But now, it appears that his luck might be running out. A new teaser trailer by Paramount has fueled fans' suspicions that Walker will die this season.

It's not yet clear how this will happen, but the trailer shows a shot of a river with a blood-soaked hat in it. This hat is synonymous with Walker, so this cryptic shot has led many to believe that the singer will be killed off this season. If this does end up happening, it would be a major twist for the show and an interesting way to say goodbye to a character that has become a fan-favorite. However, fans should remember that this is just a teaser trailer and nothing is set in stone.
