5 Things To Expect From The 'RHOC' Season 13 Reunion

The Real Housewives of Orange County season 13 reunion begins Sunday tonight on Bravo. From drug accusations to divorce drama and more, here are five things you should expect to see when the episode starts to air.

Vicki Gunvalson's daughter Briana, who recently lost 40 pounds in 5 months, will make a brief appearance during the reunion when she FaceTimes with her mother before it begins. "Who are you going to fight with today?", she asked the "OG of the OC."

Speaking of Vicki, she got into it big time with former friend Kelly Dodd during the taping, where the former accused the latter of being on cocaine. It's an accusation that has made Kelly contemplate quitting the show.

Shannon Beador, whose mental state was brought up several times this season on RHOC, battled with Tamra Judge during the reunion as well. They are reportedly not on speaking terms at the moment (Tamra also called her an a**hole before the taping began).

Newbie Emily Simpson came prepared for her first reunion, so much that she brought a "revenge binder" that featured notes about several of her RHOC costars!

Fellow newcomer Gina Kirschenheiter's divorce drama with estranged husband Matthew will also be a topic of conversation. He recently spent the Thanksgiving holiday with her and their three children over the weekend.
