"One of the reasons I wanted to talk to you was because I don't want your feelings to be hurt like the other day when I heard that you weren't happy about not being included in Kylie's graduation," Kris begins the conversation.
Caitlyn is clearly upset over the snub. "It wasn't me making that decision. It was you making that decision. I was so disappointed in everybody," she told her ex. "For 15 years of my life I carpooled kids every day …some days I would spend three or four hours in the car. [It's] a slap in the face when you don't even get invited to their graduation."
Kris responds by bringing up Caitlyn's big reveal in Vanity Fair this past June. "That's exactly how I felt with the Vanity Fair article because I spent 25 years of my life and 18 hours a day..." she says before being cut off by her ex.
Caitlyn bites back, "Vanity Fair was months ago, we're talking about what happened just a few days ago."
Caitlyn already addressed the tension between her and Kris, who were married for 23 years, in an earlier episode of I Am Cait.
Upon meeting each other for the first time, Caitlyn said, "We've moved on, both of us, but I don't want to throw all of the good times away. And for the kids, Kendall and Kylie, I don't want tension. I don't want to put them in a tough position. This is really very, very difficult."
