We meet this character in season 1. She starts off as a romantic interest for Jamie Dutton, but don’t think that this is the only purpose of this character. Christina aims to promote liberal policies, except in Bozeman it is harder than it looks, especially since the town is stubbornly stuck in the past.
When Jamie Dutton turns his attention to politics, Christina becomes his political advisor. We’re pretty sure her hate for John Dutton is one of her motives for doing so. Christina adds a new element to the show and her subplots spice things up.
We only met this character towards the end of Season 4, so we did not really get to know her. However, we loved the sweet relationship that developed between her and Jimmy Hurdstrom.
Emily is a vet working at 6666 Ranch. She helps at Yellowstone when they need her, which brings her close to Jimmy, and the two hit it off. No spoilers, but the two together departed for Texas at the close of the season so we are not sure we will see them back in Season 5.
Kathryn Kelly – Emily
“Yellowstone” was the break this actress needed. Born in 1979 in Atlanta, Georgia, Kelly has captured the hearts of audience members with her tender on-screen romance. To this date, the actress has appeared in the TV series “Powers” and “Nashville”. She has also made some cameos in the film “Fist Fight” and “The Originals”.
As said, "Yellowstone" was really when audiences saw some of Kelly’s acting abilities and hopefully, it will not be the last. There is also a British actress called Katherine Kelly. Thank goodness their names are not spelled the same else that would be confusing.
Katherine Cunningham – Christina
This actress has a long history of acting. Her roots are to be found on stage where her parents and siblings took part in local theatrical productions. Interestingly, Cunningham majored in Biology at Illinois University, but we can see her true passion has always been acting.
On stage, she acted in “The Turning of the Screw” and on the silver screen, she made the cast of “Condor”, “Mind Games”, and, of course, “Yellowstone”. She has made a few cameos on other series such as “Timeless” and “NCIS”. The actress is currently married to Mark Anthony Rutledge.
This character adds a unique twist to “Yellowstone” and brings out another side to John Dutton. Raised as a vegan, Summer believes that consuming meat and any product from animals is essentially cruel.
The fact that she is an environmental activist simply means she won’t fit in well with the Bozeman residents, except John who forms some kind of odd relationship with her. Summer organizes an environmental protest, but it only lands her and her fellow protestors in a lot of trouble. This is Bozeman after all.
