"I should get something off my chest and probably her, too," Caitlyn tells the cameras, in a clip posted by E!
The two were married for more than 20 years and have two daughters, Kendall and Kylie. They announced their separation in 2013 and divorced sometime later. Kris has been vocal about struggling to deal with Caitlyn's transition.
"I don't want tension," Caitlyn says before Kris arrives.
"Oh my goodness, look at you!" Kris says after Caitlyn opens the door. "Nice shoes!"
The two look at each other for a few seconds, seated in the living room, right before Caitlyn says, "So..."
E! News adds that in an earlier clip released last month, Kris breaks down and says, "You're sensitive and amazing to all these new people in your life, you're just not so sensitive and amazing to the family that you left behind."
Caitlyn then says, "it doesn't mean I didn't love you or the kids."
"I Am Cait" airs Sunday at 8 p.m. EST.
