'Sister Wives' star Kody Brown calls ex Christine 'Machiavellian' and says he has 'anxiety attacks' when he drives past the house they shared in Arizona

• Kody Brown calls ex Christine Brown 'Machiavellian' on "Sister Wives." 
• He also admits to having "anxiety attacks" when he drives past her old house in Arizona.
• In their first encounter since Christine moved to Utah, the exes talk about plans for Christmas.

Kody Brown's first encounter with his ex-wife Christine Brown since she moved from Arizona to Utah continues on Sunday's episode of TLC's "Sister Wives." Kody doesn't hold back when reflecting on his feelings toward Christine in his confessional interview.

"I think she's Machiavellian," Kody tells the camera, remembering the conversation, which went from discussing their holiday plans to his lingering resentment toward her for leaving him. "She plays nice while stabbing you in the back."

Over the tense lunch, Kody also admits to Christine, "I drive by your house, and I'm having these, like literally anxiety attacks." He's referring to the home they shared before her move.

On the preceding episode, which ends in the middle of a tense moment during the meal, Kody tells cameras he'd rather continue "hating" Christine than share space with her and attempt to be amicable.

The exes publicly announced their split in November 2021 after over 25 years of "spiritual" marriage. Subsequent seasons of "Sister Wives" have chronicled the messy aftermath, which includes the pair having to coordinate Kody's Christmas visitation with their now-13-year-old daughter, Truely.

Christine is in a considerably lighter mood during the encounter. She triggers Kody's reaction by laughing at their 21-year-old daughter Gwendlyn Queiroz's impersonation of Kody while he was sick with COVID-19 (as documented on season 17 of "Sister Wives").

"I really think about him less than he thinks I think about him," she tells the confessional cameras on the latest episode. "I don't really even think about him that much."

She tries to get him to admit his anger to her so they can move on and co-parent well for their kids. Christine tells cameras that Kody's "actions over the course of 10 years" are what "demolished" his goal of successfully living polygamy.

"You can't just pick favorites. You can't just stay at one person's house and expect to still have a big picture of a big, huge happy, big family," she says in an interview, presumably referring to the fact that, as seen on past seasons of "Sister Wives," Kody only stayed at his fourth wife Robyn Brown's house during the height of the pandemic.

In the scene, Kody accuses Christine of speaking badly about him to their children behind his back.

"When he sits there and he tells me to my face that I'm pitting his children against him…No, no, that is not true," Christine says, shaking the finger at the camera in her confessional interview. She added that she only acts as a sounding board for her kids when they need help.

Kody and Christine have four other biological children together other than Queiroz and Truely: Aspyn Thompson, 28; Mykelti Padron, 27; Paedon Brown, 25; and Ysabel Brown, 20.

"Listen, I've got to get in a place where I don't hate you so I don't speak bad about you to my children," Kody says to Christine's face during the meal.

As of January 2023, Kody and Robyn are unexpectedly living monogamy after Kody's two other wives, Janelle Brown and Meri Brown, also left him.

"Sister Wives" airs Sundays at 10 p.m. on TLC.
