Fans have devised a theory surrounding Michelle Pfeiffer’s new character in The Madison, which convincingly ties her to a member of

1923‘s cast. Taylor Sheridan’s landmark Yellowstone TV show ended in December 2024 with its fifth and final season. That said, John

Dutton’s (Kevin Costner) Yellowstone universe will continue expanding with several upcoming spinoffs.

Still, one of Sheridan’s upcoming Yellowstone spinoffs has no apparent ties to the Dutton family, leaving fans to speculate about how The Madison, and Michelle Pfeiffer as its lead, Stacy Clyburn, weave into Yellowstone‘s tapestry. With Sheridan’s track record, The Madison will likely link back to Yellowstone, and the most probable theory for that emerges in 1923‘s ending.

There’s an unresolved plot point in the finale of 1923 season 2, and fans believe it links Pfeiffer’s Yellowstone character to John Dutton’s family. At the end of 1923, Jack Dutton’s (Darren Mann) sweetheart, Elizabeth Strafford (Michelle Randolph), leaves the Yellowstone Ranch after Jack’s death, finally parting with the Montana wilderness that she detested.

Many now believe that Elizabeth’s departure sets up The Madison. What we know about the story so far is that Stacy and her family, the McIntoshes, relocate from New York City to Montana after a significant family death. While Stacy appears to have no ties to the Dutton family tree, Elizabeth’s unfinished story could be the missing link.

Fans have speculated that Stacy could be Elizabeth Strafford’s grandchild, since she will emerge from a city in the East and gravitate toward Montana. While Stacy and her family don’t carry the Dutton surname, Jack’s sweetheart would have likely taken her second partner’s name, establishing a new lineage. That said, she is still pregnant with Jack Dutton’s baby at the end of 1923.
