It’s not clear if Kelsey Asbille will reprise her role as Monica Dutton.
What Happens in the Trailer for Y: Marshals?

The first look at the new show is relatively brief, and it focuses on a solemn-looking Kayce Dutton considering his new direction.
“I’m changing paths, trying to find a new beginning,” he says in the trailer, followed by footage of Kayce giving chase to an SUV on horseback.

Jamie Dutton’s death during the Season 5 Yellowstone finale was seven years in the making. Everyone knew Beth Dutton wanted him dead, but it was still stunning to see it happen.

Actor Kevin Costner’s public negotiations with Paramount made it clear that his character would not return to finish Season 5. This made his death inevitable as Part 2 of the final season of Yellowstone began.

15. Elsa Dutton, ‘1883’
Elsa Dutton’s death at the end of 1883 would be No. 1 on this list of the Yellowstone franchise’s most surprising deaths, except that we see her got shot through the chest with an arrow in the very first scenes of the prequel.
The show rewinds after that to show James Dutton’s journey northwest, but everyone knows what’s coming.

14. Shea Brennan, ‘1883’
Captain Shea Brennan was an all-time great franchise character who spent the full season of 1883 in a depression. When he dies by suicide at the end, it seems fitting, but still stunning. Brennan knew what was coming all along, but viewers didn’t.

13. James Dutton, ‘1883’ (Death Revealed During ‘1923’)
James Dutton survives 1883, but during a flashback scene in Yellowstone we see him get shot by cattle thieves. It’s not until the start of 1923 that we get confirmation of his death, however. It was an underwhelming end for the patriarch.

12. Margaret Dutton, ‘1883’ (Death Revealed During ‘1923’)
Margaret Dutton’s death was also unexpected. Like James, we learn she died from Elsa’s voiceover at the start of 1923. She froze to death after James died.

11. Claire Dutton, ‘1883’
Aunt Claire Dutton was a grouch widow set to join the Duttons as they advanced northwest from Texas in 1883. In retrospect, there’s no way she would have survived the journey, but her death by suicide foretold of the great tragedies to come.

10. John Dutton, ‘1923’
The original John Dutton died in Ep. 3 of 1923 Season 1, and it’s likely he’d rank higher on this list if we got to know him a little better. Similarly, his wife Emma (Jack Dutton’s mom) doesn’t even make this list.

9. Ennis, ‘1883’
Elsa Dutton falls in love with Ennis during 1883, and they seem set to get married and grow old together. This is the first time this franchise really toyed with our emotions. His stunning death midway through the series changed Elsa’s mood forever.
