Y: Marshals , Taylor Sheridan's new Yellowstone spinoff, opened with a pretty surprising update for fans: Monica Long Dutton (Kelsey Asbille) had died , leaving Kayce Dutton (Luke Grimes) and their son on their own. This was definitely not the cast shake up I was expecting from the new show , and it's left a lot of fans feeling a lot of different emotions.

"Kayce] and Monica was the only real functional relationship in the Yellowstone series. They communicated and sometimes were at odds but always found a way to support and respect one another. It’s a shame to loose that," one [Reddit user posted , while another said, "Soooooooo happy Monica is gone!!!!!"
