Luke Grimes on 'Yellowstone' ending: 'Heartbreaking'

Yellowstone is nearing its end, and one of its leading stars, Luke Grimes, who plays Kayce Dutton, says the ending is heartbreaking.

During an interview with TVLine, he said he tried to delay reading the script for the last episode because he anticipated the devastating conclusion.

“I mean, it’s the end — the end-end,” the actor who played Kayce Dutton said. “I had no idea how the show was going to [wrap up], and I wanted to save reading that episode for the very last second.”

Ultimately, Luke faced the inevitable and explained the emotional impact of the ending, “I was a mess,” the year-old admitted. “It’s beautiful. It’s profound. It’s heartbreaking.”

Elsewhere in the interview, Luke promised an explosive finale, “They won’t feel like they’ve wasted their time for the past six years.”

In the meantime, Yellowstone has seemingly changed since the death of Kevin Costner's John Dutton.

After hinting the character took his own life in the premiere, director Christina Voros revisited the death scene by revealing new details that it was not a suicide but, in fact, a murder.

"It's not something that you could pull off in exposition," she told THR after the scene was shown in episode 11. "It wouldn't make sense. I also think the violation would not be felt the same way."

"There is something terrifying about people breaking into your home and putting you in a chokehold, and then murdering you and framing it as suicide," she continued.

"There's no way that could resonate unless you saw it. In our story, it's also the last moment we were with John."

"To have created this character who is so bold and brave and noble and strong, the violation of that person being taken off guard when they thought they were safe and experiencing this horrible death, it's supposed to be infuriating," the filmmaker added.

"Beth and Kayce, and Wes weren't there. They're solving the mystery. But I think it's important that the audience is there to witness it," Christina concluded.
