The sibling rivalry between Khloe and Rob Kardashian has been going on for the entire 12th season; and as the season comes to a close, Khloe makes it clear she’s still not happy with Rob in a teaser for the finale.

Khloe asks Scott Disick and Kendall Jenner if any of them have caught up with Rob sent he’s been MIA all season long and embarking in his controversial relationship with Blac Chyna. Disick admits he spoke with Rob not too long ago. And Khloe reveals she tried to reach out to him herself.

“I sent him a text and said ‘Hey I really miss you. This isn’t the way things should be. I hope Chyna’s pregnancy is going well.”

Disick agrees that was the right thing for Khloe to do.

“Totally.”

Khloe says his response was simple with, “Love you too.”

She adds that she was disappointed, “There was no engagement afterward.”

“You’re so happy and you’re out and about. And I want you to be so happy. But why can’t you involve any of us?”

Jenner and Disick agree that Rob still has his guard up when it comes to his family considering all of the drama he has experienced with them in the past and even this season when it came to his relationship, engagement , and pregnancy with Chyna.

Still, Khloe is convinced that Rob needs to “man up” and help “fix the situation.”

She also seems bothered that Rob still speaks with Disick.
