Season 4 of Selling Sunset will have a major shakeup since Christine Quinn revealed Brett Oppenheim left The Oppenheim Group, which he started with his twin brother, Jason.

“Brett has left to start his own brokerage,” the model-turned-realtor, 31, told Glamour in an interview published on August 15. Much of the inner-office drama during season 3 was because the ladies felt Mary Fitzgerald got preferential treatment from Jason, 43. The pair have been friends for 15 years and previously dated for about a year. Mary, 40, is now married to Romain Bonnet.

“The girls are fed up with the favoritism of Mary in the office, we don’t know who will move where,” added Christine. “It may be the battle of the brokerages! I think season four is going to be the juiciest season ever.”

Looking at The Oppenheim Group website, Brett is nowhere to be found and Jason is listed as the president and founder. However, Brett placed a link in his verified Instagram bio for a company called Oppenheim Real Estate, which features Brett as its president. It does not look like he has a team built up quite yet, considering there are no other staff members listed anywhere. 

The two brokerages seem to share a lot of similarities, so it will be interesting to see how the brothers parted ways — and if they’re still involved in each other’s businesses — during season 4. Brett shared a video of him and Jason working out together on August 4, so they seem to still be on good terms. 

Sadly for fans, season 4 may be far away due to filming restrictions amid the coronavirus pandemic. “Full disclosure, I really don’t know about season 4,” A-list realtor Maya Vander told Metro on August 11. “With the whole COVID-19 thing, I don’t know when production could happen. Things in the United States are not that great.”

If and when the new season finally starts filming, it seems there will be drama about the business but not between some of the coworkers. Christine revealed she and Mary decided to bury the hatchet after their falling out during season 2 when Christine called her pal an “idiot” during an open house. 

A few days before her sit-down with Glamour, the ladies hashed out their issues over FaceTime. “I was like, is this a butt dial? I couldn’t believe that she was calling me, I actually moved a work meeting because I wanted to talk to her,” Christine explained. “ So, her and I were sitting on FaceTime for a good hour and a half. And then, you know, we just decided, let’s get together like, let’s do this. It was so nice because it was something that was weighing on me for so long. I don’t know why we let this silly stuff get in the way of the solid friendship that we did have. I’m glad that we came to a really great place.”

As far as her tension with Chrishell Stause, Christine said she wants to “put the past in the past,” but she’s still blocked on social media by her coworker.

We seriously *can’t wait* to see what happens next!
