Now that Rob's in Dallas with Khloé & Lamar, the great news is that our gal-pal Khloé has someone to hang with during the day!
The bad news? Rob is going through some serious stress.
It's obvious to KoKo that something is wrong with her brother, especially when they're driving and Rob becomes fixated on the idea that he may have accidentally hit something on the road.
"Rob is insisting to U-turn after U-turn to go to the same place to realize over and over and over again that nothing was hit, nothing is there," Khloé says. "And that's concerning me because he's losing it, like truly losing it."
Khloé has finally had enough of Rob's O.C.D. ways and makes him pull over. While Rob checks underneath the car, around the sides and everywhere he can think of to ensure he hasn't hit anything, Khloé takes the keys.
Visibly upset about his loss of control, Rob walks along the side of the road while his sister trails after him...
"I really am worried about Rob," Khloé says. "I definitely think he has a bigger problem than what he's ready to admit that he has. I believe he needs to speak with someone—that it could help him—but I know that's not going to happen because, in Rob's head, nothing's wrong with him."
Will Rob admit he has a problem or will his compulsive behavior continue to drive a wedge through his life?
