It is later revealed that part of what drove them apart was that Kayce got Monica pregnant and they planned to keep the baby. That is when John forced Kayce to take the brand. Before the series, he was an ex-Navy SEAL who settled on the Broken Rock Reservation with his wife Monica and son Tate.
Kayce Dutton
He has a contentious relationship with his father, John, though they share a love of ranching and the land. They were estranged for many years, in part because of Kayce's relationship with his wife, Monica, and his decision not to let his son Tate get close to the rest of the family.
John later explains to Monica that he branded Kayce for disobeying him when Kayce got Monica pregnant and Kayce refused John's demand to make Monica abort the child. John branded Kayce, which drove a wedge between the two and caused Kayce to enlist in the Navy where he became a SEAL.
The underlying reason for John Dutton's dislike of Jamie is their differing personality and views on life. It is why they often fight, argue, and even work against each other in various stages of their life. Of course, it's also possible that John dislikes Jamie because he's adopted and not a true-blooded Dutton.
He went to Harvard, became a prominent lawyer, and protected his family to the best of his abilities. And yet, all the Duttons have given him is mistrust, abuse, and hatred. The Dutton family hates Jamie because he is not a true Dutton.
Those are two men who like I just said there's brotherly love and there's competition to an extent and they fight it out like two bulls, and they move on. That's it. That's just the way of life on a ranch, especially the Dutton ranch. There you have it!
John and Jamie have a complicated relationship throughout the show. Though John says he does love Jamie, he doesn't show it, and he is particularly harsh on his adoptive son.
Beth finally learns another deep family secret: John Dutton has been chucking corpses on the Montana border for years; in fact, the episode began with a young Rip (Kyle Red Silverstein), who at the urging of a young John Dutton (Josh Lucas), discards the body of a cowboy who got a little too lippy about his beloved ...
Garrett Randall was the birth father of Jamie Dutton and the primary antagonist for Season 4. He was convicted of killing his wife when Jamie was a young boy and lived by himself on his farm after being released from prison. He blamed drugs on his wife's death and the reason for her death.
Brecken Merrill as Tate Dutton
Brecken Merrill plays Tate, Kayce and Monica's son and John's only biological grandchild.
Tate Dutton is the son of horseman/ranch hand Kayce Dutton and schoolteacher/professor Monica Dutton.
WHO IS YELLOWSTONE'S MONICA DUTTON? The wife of Kayce Dutton (Luke Grimes), Monica is a Native American who lives with her family on the Dutton ranch. In Season 1, Monica serves as a teacher at the reservation's school, but in Season 2, she joins the University of Montana as a professor.
It is later revealed that part of what drove them apart was that Kayce got Monica pregnant and they planned to keep the baby. That is when John forced Kayce to take the brand. Before the series, he was an ex-Navy SEAL who settled on the Broken Rock Reservation with his wife Monica and son Tate.
So there you have it. Monica left Kayce because she was jealous, traumatized, tired, and fearful. Or maybe she just realized that he was not worth it.
Family & marriage
John and Evelyn Dutton were blessed with three more children: Kayce has two brothers (Lee and Jamie) and a sister (Beth).
After Jamie learned about his adoption, he asked Kayce for a favor, saying, “I need some advice, brother… If I can still call you that.” Kayce replies to him, “Until the day you die, you better never call me anything else.” This implies that Kayce had an inkling about the adoption.
Jamie learns that he is adopted when his assistant hands him his birth certificate.
When Beth was a teenager, she got pregnant. She sought help from Jamie, who assisted her efforts to get an abortion. But, in order to keep the pregnancy from leaking to the press and embarrassing the family, Jamie took Beth to a free clinic on a Reservation, where sterilization was mandatory with abortions.
Jamie Kissed Lord John After He Refused His Body
In the show, it ended at that, to deviate from the audience's expectation, and to focus instead on true friendship and compassion. But in the book, Jamie kissed Lord John after he refused his body, intimately but not in a sexual way.
It was there that the friendship began to blossom over weekly chats. It was over one of these chats that John professed his feelings for Jamie. Even though Jamie was unable to return the romantic sentiment it's proven as time goes on that Jamie does love John, similar to the way that Claire loves Frank upon her return.
It was eventually revealed in Yellowstone season 3 that when she was a teenager, she became pregnant by Rip.
While she is scared that it may damage her relationship with Rip, Beth does tell him about her being sterile.
