Khloe Kardashian Kills It as She Transforms into Kris Jenner

"It's two hours away. It's two days of your's so stupid," Kendall said of Kylie missing the trip.

It wouldn't be a "Keeping Up with the Kardashians" season finale without at least a little sisterly drama.

During the Season 15 conclusion Sunday night, which documented a family bonding trip to Wyoming, Kendall Jenner became angry with her younger sister Kylie for being a no-show after pulling out last minute.

Kendall vented her frustrations to her sister, Khloe Kardashian, who expressed that it was "so amazing" Kendall came on the trip.

"The fact that Kylie didn't come..." Kendall began and Khloe added, "It's so mean." According to Kendall, Kylie chose to stay in Los Angeles with her baby daddy Travis Scott and their daughter, Stormi. However, the supermodel flew from Europe in the hopes of spending time with her sister.

"She, like, doesn't really leave L.A. much," Kendall told Khloe. "It's two hours away. It's two days of your's so stupid."

"I get that Kylie didn't want to come because she wanted to hang out with Travis and Stormi," the reality star added in a confessional. "But it would have been nice to see her and nice to hang out and have a family experience. You know, like we all have things to do and we all made it a point to be here."

Later in the episode, Kylie Facetimed Kendall to see how the trip was going. Kendall admitted to her sister that it "sucks a little" because she thought her little sis was going to be there.

"It's a place that we would always come every summer so I was excited and I came in from Europe thinking you were going to be here," Kendall said. Kylie said she couldn't come because Travis wanted Stormi at one of his shows.

"I love Kendall so much and now seeing all the sentimental value that this trip has," Kylie relayed in a confessional. "I am bummed out that I missed it but at the same time I know I need to be here and hold it down."

"I feel really bad I didn't know how much this trip was to you," Kylie added to Kendall on FaceTime. "I'll make it up to you. I promise we'll do something when you get back."

On a happier note, the family ended their trip with one final bonding exercise: impersonating one another. The unique idea, of course, was made up by momager Kris Jenner.

"My mom had this crazy idea for one last final team building activity," Kourtney Kardashian told a confessional. "She thought it'd be really funny just to each come to dinner tonight dressed as a different family member."

While E! already gifted us footage of Kendall's hilarious, yet savage impersonation of Kylie earlier this week, the finale unveiled the rest of the family's spot-on impresssions, complete with hair, makeup and costumes. Khloe and Kris dressed up as one another, while Kourtney imitated Kim and vice versa.

Khloe, wearing a brown pixie cut wig and giant gold hoop earrings, flat-out roasted her mom, pretending to yell at Kris' assistant, Matthew.

"Matt! Vodka! You have my Birkin, right? Thank God," Khloe, as Kris, shouted while holding a martini glass.

At the dinner table, Khloe told Penelope Disick, who was dressed as Kylie, to sit next to her.

"I have my Kylie, my billion-dollar baby," Khloe joked. "Now she will always be the dearest in my heart for a billion reasons."
