Just when you thought the pilot season of "I Am Cait" couldn't get any more emotional, E! has released a clip teasing Caitlyn Jenner and Kris Jenner's first meeting. A majority of the former Olympian's children, including Kim Kardashian, Khloé Kardashian, Kendall Jenner, and Kylie Jenner, have allowed their introductions to their father's "true self" be filmed for the docuseries. Kris Jenner, Caitlyn Jenner's ex-wife, has not appeared on the show -- until now, that is.

As was reported by People magazine, an upcoming episode of "I Am Cait" will feature a tense sit-down meeting between Caitlyn Jenner, 65, and the "Keeping Up With the Kardashians" star. The short video kicks off with Kris Jenner, 59, stopping at her ex-husband's Malibu mansion to see her for the first time since her transition for a gut wrenching, but necessary, discussion. Although little from their meeting is shown, the clip suggests the former husband and wife will discuss their past relationship and, hopefully, ease some of the tension between them. The clip shows Caitlyn Jenner discussing all the "great times" they shared in a voiceover.

"We did have a lot of great times. We've moved on, both of us, but I don't want to throw all the great times away," Caitlyn Jenner says. "And so 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."

This is the second clip E! (via People) has released teasing Caitlyn Jenner and Kris Jenner's first encounter. The first showed bits of their tense conversation with a strong focus on Kris Jenner's perspective. In the clip, the "KUWTK" star is shown crying as she explains to Caitlyn Jenner she feels that she didn't treat her family very well following her transition.

"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," she says.

Kris Jenner, and her children, have been very open about the fact that they feel Caitlyn Jenner has been disrespectful since completing her transition from male to female. In a previous episode of "I Am Cait," which aired Aug. 16, both Kim Kardashian, 34, and Khloé Kardashian, 30, sat down with Caitlyn Jenner separately to discuss comments she made during her coming out interview in Vanity Fair. Both of Caitlyn Jenner's step-daughters expressed to her a feeling that she should have chosen her words more carefully to avoid painting a negative picture of their mother.

"Had Kris been more accepting, we still would be together," Caitlyn Jenner maintained at the time.

"I Am Cait" airs Sunday at 8 p.m. EDT on E! Check out the emotional clip below:
