The drama went down when Kris Jenner suggested a therapy session during a road trip with her daughters.
In a preview clip from the upcoming season finale of "Keeping Up With The Kardashians," matriarch Kris Jenner suggested having a little family therapy session while traveling in a van in Wyoming, asking her daughters to "pick one person here and tell them what's the one thing you'd love to focus on to strengthen in your relationship."
Kim -- who was sitting next to Kourtney -- piped up and confessed, "I want to fix my relationship probably with Kourtney, for those mean reasons and those mean comments."
"For you saying them?" asked Kourtney, as Kim agreed, "I can be so mean."
Khloe chimed in and said they both do it to each other, calling it "equal."
As for her family therapy partner, Khloe also chose Kourtney to work with, as they "sometimes fizzle." She added, "I would love to get us back on course and not be so reactive, for myself."
Staring at Khloe, Kris had a moment, explaining bluntly, "It's the way you say things." Ouch.
Kendall then took her turn at the mic and revealed "there's a lot of judgment between all of us" and used her eldest sister as an example.
"Like Kourt -- you say it a lot, like you're always like 'We cant be so judgmental,' but you are too, like we all have to realize that we all are," the model detailed.
Kris interrupted again to say she thinks people hurt the ones they are closest to, which can be remedied if they work at it.
"The love we have is so unique and it's so special, we have to treat it like a little precious gift from God," the momager said.
"Like a little precious baby," Khloe cooed in a high voice.
Find out if the therapy-on-wheels endeavor brings the family closer or drives them apart on the season finale of "Keeping Up with the Kardashians," which airs Sunday night at 9 p.m. ET on E!
