'Real Housewives Of Orange County' Cast Demands Answers From Vicki Gunvalson About Brook Ayers In Reunion Preview

The first official preview for Bravo's "The Real Housewives of Orange County" reunion special is finally here and it looks like the gloves are coming off. After a season full of speculation about Brooks Ayers' suspicious cancer diagnosis, the cast is demanding answers from Vicki Gunvalson -- and they just may get them.

Bravo released the first official trailer for the highly anticipated "RHOC" reunion and it's every bit as chaotic as Season 10 was. The "Real Housewives" surround host Andy Cohen on two couches to discuss the drama and, of course, Brooks Ayers will be brought up multiple times throughout. Vicki's, 53, biggest doubters Meghan King Edmonds, Heather Dubrow and Shannon Beador will get emotional about the subject, suggesting that Vicki may have known more than she let on. At one point she and longtime friend Tamra Judge take a little sidebar, during which Tamra, 48, urges her to come clean about what she did -- or didn't -- know. Andy, 47, will also bring out Vicki's daughter, Briana Culberson, to hear her side of the Brooks cancer drama. Other major subjects of discussion during the multi-part special? David Beador's affair, Meghan's relationship with husband Jim Edmonds, and more.

Heather, 46, spoke out about the reunion drama on Oct. 1, clueing fans in as to what they should expect. She hinted that she and her "RHOC" co-stars would be digging for answers about Brooks since Season 10 came to a close with little to no resolution. During the same interview she addressed comments Brooks made about the show, claiming it thrived off "manufactured drama." Heather assured viewers there is nothing fake about "RHOC."

"RHOC" came to an end on Monday with a drama-filled episode filmed during Tamra's baptism party. The entire cast gathered to celebrate her re-birth in episode 19, but found themselves unable to steer away from old drama. While standing around enjoying cocktails and snacks Heather revealed to Shannon, Meghan and a few other "RHOC" cast members that she had heard a new story about Brooks involving her husband. She said he had been claiming that early on in his treatment he had gotten so sick he had to call Terry Dubrow in the middle of the night who then sent a colleague over to administer an IV. Coincidentally, Shannon had heard the same story from Vicki months prior. When confronted by her co-stars Vicki retreated to her limo where Tamra attempted to reason with her to no avail. She drove off, proclaiming that she didn't care about the "RHOC" cast or the drama anymore.

Part one of the "RHOC" reunion airs Monday, Oct. 19 at 9 p.m. EDT. Check out a preview for the special below:
