Rob Kardashian moves into a new home, Khloé calls Kris a liar

Sunday's episode of Keeping Up with the Kardashians included a change of address and a change of heart—sort of. Kind of? We certainly hope so.

Rob Kardashian returned to the series and moved into his own home, after rooming with his sis, Khloé Kardashian. Remember when things got a little tense after Khloé caught Rob and Blac Chyna together? Yeah, it seems they still hadn't made up when this episode was filmed.

Khloé said Rob hadn't spoken to her since moving out. And, when Kris Jenner told Khloé that Rob got a new house (with some financial assistance from his mom), she wasn't exactly happy for her little bro.

"So, you know how I helped Kylie (Jenner) get a house," Kris began. "So, Robert is doing the same thing, and he's getting a house."  Khloé was speechless. "It's his money," Kris assured her.

"You are one of the world's biggest liars," Khloé told her mom, who insisted Rob had the money for the down payment. "I'm just allergic to (expletive)," Khloé said.

We love Khloé, but whether Rob got money from his momager (or his nephew, Mason Disick, who got $100 from the tooth fairy), Khloé should be happy for her bro, right? Apparently, she feels like her mom is being a little bit of a hypocrite.

"I would have such deep fights with my family because I was enabling Rob by letting him live with me," Khloé said in an on-camera interview. "And, then the one person who yelled at me the most, which is my mom, now she's helping Rob? I just find it mind-blowing."

She also made it very clear that her assistants wouldn't be helping with Rob's move. "Rob's not inconveniencing my life," she told her mom over the phone. "He's done that enough for years."

"What I'm so confused about is why Rob has such issues with me all of a sudden," Khloé told the camera. "I'm allowed to say I don't want strangers in my home. I just want Rob to reach out to me. So, I'm just waiting."

But after talking to her BFF, Malika Haqq, she called Rob and stopped by his new digs. Unfortunately, he wasn't home.

In the final moments of the show, Khloé seemed to be interested in moving forward with her brother. "I decide to just be the bigger person, and I don't really see the effort he's making on his end," she said. "So, I'm not really sure what else to do as of now."

Hopefully we'll see these siblings resolve their issues soon. Keeping Up with the Kardashians airs Sundays at 9 p.m. ET/PT on E!
