‘KUWTK’ Recap: Kim Bashes Khloé As A ‘Miserable Person,’ After Argument Over Troubled Brother Rob Escalates On Family’s Thailand Trip

Kim Kardashian bashed sister Khloé on Sunday’s Keeping Up with the Kardashians during the family’s Thailand vacation, after the sisters again disagreed about their troubled brother Rob’s downward spiral, and how to help him through it.

As RadarOnline.com has reported, Rob’s exploding waistline and estrangement from his family has caused concern, sparking ongoing drug rumors.

On last week’s episode, Kim and Khloé clashed over how to handle Rob and more rancor followed on Sunday, culminating in Kim telling Khloé she was a “miserable person.”

First, while they traveled on a yacht, Khloé told stepbrother Brandon Jenner that when she lived with Rob, “He never left the house” and was “definitely very depressed.”

Then Kim chimed in, “I feel like Rob needs to get it together and go away somewhere. It’s been over a year now he’s been like this. We’ve all tried to help him.”

Khloé snapped at Kim, “That’s what frustrates me about you so badly,” calling her older sister closed-minded about their brother’s struggles.

But Kim insisted, “The problem is he spends hours a day with mom on the phone, but he won’t do anything.

“I’m a little bit more of a tough love kind of person.”

A frustrated Khloé explained to the cameras that she had been very close to Rob while Kim had been living her own life.

Ultimately, Khloé stormed below deck, telling Kim and Brandon she wanted to go home. Kim told the cameras Khloé should take care of herself, not Rob.

Meanwhile, Brody Jenner told Khloé that her brother “is dealing with some serious issues” and “really needs help.”

Khloé confided that she felt guilty because Rob had lived with her and then-husband Lamar Odom: “Even Rob has said, ‘Being in that house, it was so dark, it made me do dark things,” she said.
