In this exclusive sneak peek at Friday's new episode, the daughter-dad duo pick questions for one another that the therapists will later ask in a lie detector experiment. For Brandi, that's wondering if her dad hustled drugs, while Guy asks yet again if his daughter was hustling her body.
"Did you ever sell drugs yourself? Marijuana?" Brandi asks Guy, and a flashback plays in which she says, "I grew up with pot in my backyard. I think that he was a drug dealer."
Guy doesn't appear to mind the inquiry, but Brandi isn't too happy about the one he comes up with for her.
"Were you ever an escort?" Guy asks next, a repeat of episode two's drama where Brandi's dad said, "You told me you escorted some of these rock bands."
Brandi -- who denied being a hooker and ever saying that -- appears just as hurt as she was then, clarifying, "That's your question?"
Even "Mob Wives" star Renee Graziano thinks the Q crosses a line: "Why the f-ck do you want to know if your daughter was ever an escort. Seriously?" she asked in a confessional.
"I can't believe that you still can't let go of that," Brandi says later.
But there were two people who liked the question: Dr. Venus Nicolino and Dr. Ish Major. With Guy's question receiving the green light, Brandi will be forced to answer a subject she's already sick of this Friday.
