'1923' star Michelle Randolph says the cast still don't know how Dutton family tree connects to 'Yellowstone' because Taylor Sheridan 'likes to keep us on our toes'

• Warning: There are spoilers ahead for the sixth episode of "Yellowstone" prequel, "1923."
• Michelle Randolph said the cast doesn't know how they are related to the modern-day Duttons.

There are just two episodes left in the first season of "1923," and for those hoping that the finale will reveal the mystery of which couple is the grandparents of Kevin Costner's "Yellowstone" character, we're sorry to say you might be left disappointed.

Speaking to The Hollywood Reporter, Michelle Randolph, who stars as Elizabeth "Liz" Strafford, on the Paramount+ series said that she and the rest of the cast don't know how their characters connect to the modern-day Duttons.

The actor said that Taylor Sheridan, who helms the prequel and cocreated the flagship series with John Linson, hasn't divulged the full family tree to its stars just yet.

"We all go back and forth on what we think is going to happen, but Taylor likes to keep us on our toes," she said. "So we're just as confused as everyone else."

While Randolph could just be playing coy so as to not spoil anything for fans, if she is telling the truth, audiences will have to wait until the show's second season to have their questions about the Dutton lineage answered.

However, this hasn't stopped Randolph and her costars, which include Hollywood heavyweights Helen Mirren and Harrison Ford, from discussing their own theories.

She said the cast " like to debate" what they think is going to happen and "would love" for it to turn out that her character is the "Yellowstone" protagonist's grandmother.

"Then I could win the fun, joking argument that we all have with each other," she said.

Randolph's comments aren't entirely surprising as James Badge Dale, who played her father-in-law, John, said he also didn't know how his character was related to his namesake on the flagship show before he was killed off in episode three.

"I don't know the tree," he told the same outlet in January. "This was the running joke. Harrison and I would be like, 'I think we're related, I don't know how.' We all need a flow chart."

"I've seen them online, when people have tried to create them. I don't know if those are accurate or not," he said of the countless fan-made family trees that attempt to make sense of the ever-growing Dutton clan.

"And here's the thing, this is Taylor's universe," Dale continued. "We could be saying one thing or thinking one thing, and Taylor can decide something else."

Dale then joked that future, as-yet-unannounced spinoffs set in the middle and latter half of the 20th century could "change it up" by revealing narrative threads and Dutton relations that upend what we thought we knew about the family.
