“Meghan has gone above and beyond trying to prove Brooks wrong, but I’m here to tell you what everybody’s saying," Barney tells Gunvalson in a sneak peek shared by Us Weekly last week. "I don’t want you to get defensive, I don’t want you to get mad …it’s [just] starting to wear on me, and it’s like shit does he have cancer, is he lying?”

“What does he have to do, die, to prove somebody wrong?” Gunvalson responds.
