Yellowstone's Luke Grimes shares true Kayce knowledge of Jamie adoption 'Not in the dark'

“And it’s funny you ask because I could be completely wrong about that,” Luke said.

“But the line always felt to me like, ‘I know, but it doesn’t change the fact that we grew up together. I love you and you love me. This is stronger than biological stuff’.”

As for where Kayce is headed in season five, Luke admitted: “Honestly, I 100 per cent do not know. I haven’t read a script yet.

“We start in a few weeks, so I’ll probably start getting scripts right before we show up. That’s usually the drill.”

As production is getting underway slightly later this year, fans may have to sit tight a little longer before the explosive Dutton saga begins its next chapter.

Yellowstone seasons 1-4 are available to stream on Peacock in the USA. Seasons 1-3 will premiere on Paramount Plus in the UK later this year.
