In this new sneak peek for this week's episode, it looks like Kendall and Kylie still haven't worked out the kinks in their friendship as the sisters meet Caitlyn Jenner at the race track and Kylie ends up leaving to go hang out with her friends.
"I actually can't believe that Kylie is leaving right now," Kendall tells the camera, "just because we never get to spend time with each other. I travel a ton for work and even when I'm home in L.A. I feel like I never get to see Kylie as often as I'd like to...and to have a moment to spend time with your dad and your sister, I would take it."
When Cait asks Kendall what the deal is with Kylie, Kendall tells Cait that "she doesn't have her priorities straight."
Either way, it looks like Cait and Kendall still had a really awesome time!
