This week on "Married to Medicine," Quad, determined to prove that she's more than a housewife, debuted her first pop-up shop to bring her business front and center. And it appears that Quad and Lisa Nicole's feud had no signs of letting up as someone gave Quad some information that she could use against Lisa. 

At Quad's Picture Perfect Pup event, Dr. Heavenly told Quad that perhaps it's time to drop the feud with Lisa Nicole, but Quad was not having it and told her that she refused to attend any event wherein Lisa would be present. 

Quad's behavior certainly baffled the doctor, as she took to her blog to ponder "what is the cause of discord amongst this group of women." Heavenly surmised that perhaps the reason why it's so hard for them to get along with each other is because of their different backgrounds and experiences. 

"I do think that maybe we should all take the time to consider another person's background and why they view things the way that they do," she wrote. 

Later in the episode, it was revealed that Lisa and Quad were both present at Porsha Williams' event, and this seemed to upset Simone, especially since she disinvited Lisa from her Kids versus Parents basketball game just to make Quad happy. 

When Lisa talked to Quad, the latter said that since all of them lived in Atlanta, it was inevitable that she and Lisa would run into each other. But on the matter of the basketball game, Quad told her that she might not be going at all. So Lisa ended up going to the game with her kids after Simone called her to apologize for disinviting her. 

But at the end of the episode, it looked like Quad had a bombshell on her hands as a young man approached her and told her that he is allegedly being intimate with Lisa Nicole's husband. So what's next for the women of "Married to Medicine" next week? 

In the episode titled "Boys on the Side," Toya will be busy tackling the logistics for her husband's business, and next week, she'll be at odds with him on where to break ground. Meanwhile, Dr. Heavenly's daughter will intern for Lisa Nicole and she'll design a dress for her mother's dating app release party. And Lisa Nicole and Quad's feud gets heated at Dr. Jackie's fitness event when Lisa Nicole accuses Quad of publicly questioning her husband's sexuality. 

"Married to Medicine" airs Sundays at 9/8c on Bravo.
