Warning: This post contains spoilers for Season 5, Episode 13 of Yellowstone.

When it comes to saving, not all hope is lost Yellowstoneis the legendary Dutton Ranch.

After an extensive auction in which Beth Dutton (Kelly Reilly) managed to raise over $30 million by selling the ranch’s livestock and equipment, her brother Kayce (Luke Grimes) realizes how they can potentially save the family ranch . It’s so impressive that it even baffles Beth – who is known to be the first to plan a way out of any situation – that she didn’t think of it first.

“Let’s take your car. How much is that worth?” Kayce asks Beth about her Bentley, to which she quips, “It’s a lease, so it’s worth nothing to me.”

Kayce, determined to get an answer, pushes further, asking, “But what if it was yours?”

“$300,000,” she replies, prompting Kayce to ask, “And if you sold this to me for $1, would that be illegal?”

Beth replies, “It would be stupid, but it wouldn’t be illegal.”

“OK. So, I buy this car for $1. And then I take this $300,000 car that I bought for $1 and register it. What sales tax do I pay? Is it based on what I paid or the value of that car?” Kayce asks Beth, to which she replies, “What are you cooking?”

When he presses her to answer the question, she says, “The tax is based on what you paid for.”

“That’s what I thought,” Kayce says as he walks to his truck and drives off.

“Why didn’t I think of that?” Beth asks as she runs to his truck. “WHO?” She asks Kayce, to which he replies, “Give me the day, just to make sure.”

“You’re smarter than you look, little brother,” Beth says as she leans in the car to give Kacye a kiss on the cheek.

When Kayce’s wife Monica Dutton (Kelsey Asbille) asks what he plans to do, he keeps quiet about the details, saying, “The only way to save this place is to give it away.”

In this bogus situation, Kayce assumes that the family is orchestrating a “sale” to a close trusted party for an amount that vastly understates the true cost, thereby deferring any personal tax burden and the risk of losing the land entirely from the family , which is already tense following the shocking deaths of John Dutton and ranch hand Colby Mayfield.

The episode ends on that note, but leaves open the question of who Kayce might enlist in his simple tax loophole scheme to help preserve the Dutton ranch for years to come.

In an earlier scene while dancing with Monica, Kayce tells her that his plan is different from his sister’s.

“I have a different plan, one that guarantees a future,” Kayce tells Monica. “I won’t tell anyone. Not yet. But I know in my heart that it will work. And I know it’s the right thing to do.”
