The tension continued between Vicki Gunvalson and the rest of "The Real Housewives of Orange County" cast as more details emerged about Brooks Ayers' suspicious cancer diagnosis. Ayers' health has been a topic of discussion throughout most of Season 10, with many of the women doubting that he truly is suffering from stage 4 cancer. During Season 10, episode 16 of the Bravo TV series, Vicki, 53, reached her boiling point.

The episode picked up exactly where the previous one left off -- in Shannon Beador's backyard at her Aries-themed party. Unfortunately, as you may recall, the party was hijacked by drama when Brooks and Vicki decided to seize the opportunity to confront Meghan King Edmonds about her constant delving into their personal lives. During episode 16 the couple exchanged a few choice words with Tamra Barney, who was dragged into the drama by Meghan, 30, before storming out. The following day Tamra, who only just mended her broken relationship with Vicki in an earlier episode, met with her on-again, off-again BFF to discuss the drama.

The Cut Fitness co-CEO attempted to express her point of view, but was shut down by an irate Vicki who claimed she was being a bad friend. The business mogul demanded that Tamra choose a side and choose wisely. Shannon, 51, was faced with a similar decision when she sat down with Vicki later in the episode. The two met for lunch, where Shannon explained to Vicki that if she and Brooks didn't show his medical records as proof of his diagnosis, the chatter would not stop. 

While Vicki was less than open to the idea during their sitdown, it appears she and Brooks will later have a change of heart. Previews for episode 17 of "RHOC" suggest Brooks will sit down with Tamra to share the results of a recent medical test -- but is it real? Meghan, who has said in the past she can't help herself but research, will apparently do a little digging and what she finds could change the dynamic of the entire cast. 

"RHOC" airs at 9 p.m. EDT Mondays on Bravo. Check out a clip of Season 10, episode 17 below:
