Yellowstoneestablishes how John II’s story ends, but there’s little information about how it begins.Sheridan has not confirmed John Dutton II and III’s linkto the prequel characters. Wes Bentley’s Jamie Dutton announces that his father is a fifth-generation Montana rancher while setting up John Dutton’s Montana governor acceptance speech, so we can deduce that John Dutton II was part of the fourth generation. The plot suggests that John’s father could be Jack Dutton (Darren Man), a third-generation Dutton, but plenty of buzz surrounds the theory thatSpencer’s whirlwind romance in1923is the missing link to John Dutton II.

Peopleshared1923season 2 imagesahead of its August 04, 2025 release, and they confirm the continuation ofYellowstone’s biggest mystery.The1923images confirm that Spencer and Jack are alive and well in season 2, meaning that anything is still possible. Buzz exists around the possibility that Spencer dies at the end of the prequel’s second outing. Even if that’s true, Spencer could still conceive an heir to the ranch before his untimely death. Sklenar says the following about1923’s ending (viaForbes):
I mean, the finale of the series is probably one of the best things I’ve read in my life. I’ve kind of known how it was going to end since day one - Taylor [Sheridan] kind of told me. I knew the full arc of Spencer from day one, so in shooting part one, you’re mindful of where he needs to go. I’m really excited.

How Spencer Dutton Could Die In 1923 Season 2, Explained By Brandon Sklenar
Spencer Dutton died sometime between 1923 season 1 and Yellowstone, and actor Brandon Sklenar has a theory about how it could happen in 1923 season 2.
Thetrailers for1923season 2confirm that Spencer, Alexandra (Julia Schlaepfer), Jack, and Elizabeth Strafford (Michelle Randolph) all return for the second outing. All of John Dutton II’s prospective parents officially returning for the next installment signals that1923will continue to play out the Dutton familymystery in season 2.
