Yellowstone's Marshals Leaves [Spoiler] With Second-Degree Burns After Blaze

Marshals tossed a grenade into its own barn this week — literally. The Yellowstone offshoot staged a nasty fire and put country artist-turned-actor Riley Green right in the middle of it. If you were wondering whether the show would actually use its new guy, the answer is: they set him on fire.

What went down on Sunday, May 3

• Kayce (Luke Grimes) spots a blaze ripping through a barn on his property and sprints over.
• Garrett (Riley Green) is already inside, shoving horses out to safety like a champ.
• Then the bad beat: a beam collapses and pins Garrett.
• He makes it out but with second-degree burns.
• A doctor warns there’s internal damage on top of the obvious burns — lungs included.
• Everyone circles the wagons, but the show leaves just how serious this is hanging for now.

So who is Garrett, exactly?

Green plays Garrett, a former Navy SEAL who shows up at the ranch to lean on friends Kayce Dutton and Cal while he tries to put some old demons to bed. Translation: the guy is tough, trained, and carrying more baggage than a tour bus. The character’s set up as a friend in need and a powder keg — which, after this week, is now also singed.

Yes, that Riley Green

This is Green’s first acting gig, and he is not just a one-and-done cameo — he’s in multiple episodes this season. He announced the jump back in February with the kind of enthusiasm you expect when your first TV job also means hanging out with your buddy Luke Grimes:

"I’m so excited to be joining the cast of Marshals. Being on set with my buddy Luke Grimes made the experience even more memorable. This is my first go around in the acting space and I couldn’t have asked for a better introduction to this world."

If you’re curious how this all came together, Green told People in April that it happened pretty organically. He and Grimes became friends through music — Grimes has been dipping into the Nashville world, doing cowrites, and Green was helping him connect with folks. Somewhere in there, Grimes basically said, "Man, you should try acting... I think you’d be good at it," and the seed was planted.

Figuring it out on set

Green says the cast and crew were welcoming while he was juggling gigs and shoot days. Compared to touring — where you load in, play the same hits, load out, repeat — he liked that acting gives him something new to chew on every day.

He also worked with an acting coach who told him not to obsess over lines and to lock into what the other person is saying. That helped, because Garrett isn’t some easy layup role for a first-timer. The character’s got a lot of vulnerability layered under the military skill set, and Green admits he hasn’t lived what Garrett has. He leaned on feedback in the room to find the right notes.

Where this leaves Garrett

Second-degree burns are bad enough, but the bigger question is the smoke and internal damage. The show made a point of flagging the lungs, then cut us off before we could get comfortable. So, expect the fallout to hang over the next stretch — and probably poke at those demons the character came here to bury.

Marshals airs Sundays at 8 p.m. ET on CBS.
