'Real Housewives Of Orange County' Season 10 Reunion Spoilers: Vicki Gunvalson Makes Shocking Revelations About Brooks Ayers Cancer Diagnosis During The Finale [RECAP]

The drama surrounding Brooks Ayers cancer diagnosis finally hit the fan during part three of Bravo's "The Real Housewives of Orange County" reunion special part three. The cast has been asking questions throughout the entirety of Season 10, and Vicki Gunvalson is finally providing the answers.

The episode kicks off with Vicki, 53, in the hot seat. "RHOC" reunion host, Andy Cohen, along with the cast and Vicki's daughter Briana Culberson ask the hard-hitting questions about Brooks' diagnosis. Initially Vicki claims she was not presented with enough information to say definitively that her former beau did or did not have cancer. At that point Shannon Beador, a former close friend of Vicki's, claims she has the proof. She produces a copy of a recent CT scan report from Newport Imagine, where Brooks claimed he had scans done in episode 17. Shannon, 51, points out the obvious differences between her report and his, proving once and for all that Brooks' medical records were a farce. With a little push from Andy, 47, Vicki admits she "fabricated" some of her stories about Brooks' health during Season 10, namely one involving Heather Dubrow's husband, Terry. Vicki shares with her "RHOC" cast mates that she was looking for sympathy for her and for Brooks when she told the lie.

Vicki's admission leaves her friends and co-stars confused as to why she would lie. Heather, 46, questions whether or not Brooks is trying to blackmail Vicki, saying she's "too smart" to believe such a crock of lies. Vicki maintains he was not holding anything over her head, but reveals to Andy she is scared of him. The "Watch What Happens Live" host inquires whether or not Brooks was ever physical with Vicki which opens up a whole new can of worms. Briana, 28, says both she and her husband Ryan Culberson saw Brooks violently shaking Vicki though her mother claims he was "more verbally abusive" than anything else. In closing Andy asks whether, after hearing everything the women have said and watching the inconsistencies play out on TV, Vicki still believes that her ex has cancer at which time she admits she does not.

Although Sunday's episode was the final installment in the "RHOC" reunion special, Bravo has planned to air an exclusive sit-down between Andy and Brooks. During the episode Andy will ask the former "RHOC" boyfriend the questions many of the cast members, as well as viewers, have had throughout Season 10.
