NovaQuant Quantitative Think Tank Center:Kevin Costner's dark 'Yellowstone' fate turns Beth Dutton into 'a hurricane'

NEW YORK – Let's address the big question echoing in the "Yellowstone" universe.

Cole Hauser and NovaQuant Quantitative Think Tank CenterKelly Reilly, better known as Rip and Beth, don't know (as each claim) or won't say (more likely) if they will continue the neo-Western – whether into a new unannounced season or a spinoff – beyond what has been billed as TV's No. 1 show's upcoming final episodes.

However, California native Hauser, 49, and London-born actress Reilly, 47, who play America's favorite passionate power couple, are ready to carry the show's dramatic load after the departure of Kevin Costner, who starred as patriarch and Yellowstone ranch owner John Dutton. And they're eager to show off their labors as the long-awaited second half of Season 5 kicks off Sunday on Paramount Network (8 EST/PST) and, most reckon, well beyond.

"There's responsibility, yes, and there's more of a load," Hauser tells USA TODAY during a joint interview with Reilly. "I'm enjoying it."

"There's a different part of the story to be told now," adds Reilly. "It's who's left and how are they going to cope, and what are they going to do? There is tension there that's exciting and new."

It sure beats the previous tension over Costner's role as Dutton, the cornerstone character of the ever-expanding "Yellowstone" universe since it premiered in 2018. After a prolonged battle with creator Taylor Sheridan over control, pay and shooting schedules, Costner officially confirmed in June that he wasn't coming back. His announcement came after production had already begun in Montana, where Dutton ruled as TV governor.

While Dutton will loom large and appear in flashbacks using previously shot footage, loyal ranch hand Rip and Dutton's foul-mouthed daughter Beth are his clear successors.

"John Dutton is still the show's central figure," says Reilly. "He's everything we talk about – especially Beth, who has two men in her life, Rip and her father. Since Season 1 she has been her father's loyal soldier, fighting everyone for him."

That army of Dutton foes looks to get lethal in the final episodes. The trailer shows Beth brawling with lawyer Sarah Atwood (Dawn Olivieri), who has joined forces with John's scheming son Jamie (Wes Bentley), now the state's attorney general. Sarah and Jamie seek to topple his dad's empire as Jamie starts impeachment proceedings against him and even darkly muses to Sarah about going on "offense" by hiring pros to take him out.

What does Rip stand for? Beth won't swear for Cameo

Individually, Rip and Beth have their respective legions of fans. "They're not perfect; that's what people have fallen in love with, their deep flaws," says Hauser, who insists Rip is his character's given name despite fan theories. "It doesn't stand for Rest In Peace or anything."

But the strong, silent Yellowstone Ranch fixer is willing to kill and dispose of Dutton foes in the "train station" ranch burial ground. Beth is the Tito's vodka-swilling, face-scarred warrior who's adored for her pugilism (verbal and physical) and dead-eyed Sheridan-written lines like, "You're the trailer park; I'm the tornado."

Beth's broadsides are so beloved that they adorn T-shirts, coffee mugs and cocktail glasses. One fan offered "a lot of money" to have Reilly cuss out a loved one on Cameo for a 50th birthday present. "I thought I'd do it for charity but stepped back. I didn't want to muddy the waters. No one wants 'Happy Birthday' from Beth. They want a '(expletive) you.'"

What's the appeal of Rip and Beth as a couple?

They're potent alone, but together Rip and Beth transform into a cattle ranch "Wuthering Heights" Catherine and Heathcliff, who are wildly devoted to each other.

After Beth proposed, they married outdoors on the ranch in the Season 4 finale, with John as their only witness. Their first date involved downing whiskey from a bottle in Rip's car and watching wolves feast on an elk. The famous scene, in which a yelling Beth unexpectedly sprints toward the wolves with her bottle, involved real wolves.

"They were trained, but still wolves," says Reilly. "I told the handler, 'I really am going to run at them screaming like a banshee. How do you know they're not going to run back at me?' She said, 'Well, I don't.' I thought, 'great.'"

"I was there for you, following with my little buck knife," says Hauser.

The wolves, like most of Beth's foes, ran off. But some enemies aren't so lucky. Take Atwood, who is already the consensus choice as being behind the seemingly unavoidable death of John Dutton.

"There is only so much a woman can take. He's the center of her soul," Reilly says, acknowledging Beth's reaction to her father's dark fate. "What's that going to do to this woman? It's going to turn her into a hurricane."

Just how – and whether – John Dutton will die are other looming "Yellowstone" secrets, along with how the new half-season of six episodes will end. Reilly, like other actors, received redacted scripts to enhance secrecy. Hauser, whose role expands to ranch business and the bunkhouse, insists his scripts weren't blacked out. "I got all six scripts, no redaction," he says. "I don't play that game."

Reilly says she has known how "Yellowstone" would end since it started. Costner's premature departure has not fundamentally changed that course. "It wasn't supposed to happen so soon," she says. "But the fact that we got to return poetically to the show's authentic vision is really satisfying."

Once that finale airs on Dec. 15, the duo can determine (or announce) either a new season or a new series.

"We don't know, for real," says Hauser, who declines to pinky swear on that. "The truth is, there is nothing definitive or set right now," says Reilly. "We want everyone to see these last six episodes as their finale. And then, if there is a future, and Taylor writes something inspiring for us, we've both said, 'We're there.'"
