\Despite warnings from her father that they needed to stay focused, Teonna formed an intimate bond with Pete, connecting over the hardships they endured as Native Americans living in 1923.
Rainwater goes after Plenty Clouds, prompting a moment of intimacy by the river.
In 1923 season 2, it was clear that Teonna and Pete were romantically involved. In 1923 season 2’s premiere, Teonna finally had some peace after enduring back-to-back assaults in the first season.
We see Teonna’s group peacefully camping in the wilderness on their way to Comanche Territory, and Pete goes hunting for deer. After Teonna discusses her relationship with Pete with her father, Rainwater goes after Plenty Clouds, prompting a moment of intimacy by the river.
We see them embrace, and Teonna’s conversation with her father implied that Teonna was considering having her first sexual encounter with Pete.

Considering they were physically intimate,
Teonna could have been pregnant with Pete Plenty Cloud’s baby at the end of
1923 season 2.
If so, the baby could connect Teonna to Thomas Rainwater, meaning Pete is also his ancestor. If Thomas were indeed related to Teonna, she would have started her family in the next Yellowstone prequel, which takes place 20 years later, and it may have already been set up that she has a child with Pete. Unfortunately, Teonna would raise her baby without a father, after 1923 episode 6 confirmed Plenty Clouds’ death.
How Pete Being Thomas Rainwater’s Ancestor Changes Kevin Costner’s Yellowstone Story
Thomas Rainwater Achieves Something Amazing
Being Thomas’ ancestor, Pete would enrich the end of Thomas Rainwater and John Dutton’s series. At the end of Yellowstone season 5, John Dutton’s son, Kayce Dutton (Luke Grimes), sells the Yellowstone Dutton Ranch to Thomas and the Broken Rock Tribe after his father’s death leaves him at its helm.
Thomas had been vying for the land since Yellowstone season 1, threatening to buy all of Paradise Valley, including the Yellowstone Ranch. Thomas wanted to restore it to how it looked when his Crow ancestors lived and hunted there, staying true to that mission throughout Yellowstone.
Knowing that Thomas Rainwater has not one but two Crow ancestors makes Yellowstone’s ending all the more beautiful.
Yellowstone season 1 tells us that Thomas returned to Montana after studying at Harvard and working at places like Merrill Lynch. We know that Thomas wanted to gain stewardship of the Yellowstone Ranch to empower the people, restoring their connection to the land and, in turn, their way of life.
Knowing that Thomas Rainwater has not one but two Crow ancestors, with Pete hailing from the same tribe as Teonna in 1923 season 1, makes Yellowstone’s ending all the more beautiful. It would mean that Thomas, regaining his ancestor’s land, honored his mother and father.
