'RHOC' Reunion Part 3: Vicki Exposes Shannon's Biggest Secret EVER!

This week on the final installment of the Real Housewives of Orange County reunion special, the ladies recounted their traumatic dune accident in Glamis.

"It was surreal," Kelly Dodd recalled of the horrific experience. "I knew my helmet fell off and Tamra Judge's head crash into mine."

But other old wounds were opened when Meghan King Edmonds was forced to defend her lack of sympathy over Vicki Gunvalson's hospitalization following the crash.

"From what I know about Vicki, she exaggerates and makes stuff up," Meghan insisted, but Heather Dubrow, the dubbed "morality chief" wouldn't let the expectant mother get away with her excuses.

When Vicki finally started putting her voice to use, the trouble really started.

"She's so bossy," Shannon whispered of Vicki, though everyone could hear her.

"Get used to it," Vicki said in return, foreshadowing drama to come.

When the ugly conflicts of Ireland were discussed, emotions ran high, starting with Vicki and Tamra informing one another that "everyone is sick of your s**t!"

As the bickering reached its peak, Shannon was driven to her breaking point over Vicki's accusations that her husband David "beat the s**t out of her."

"I have proof," Vicki claimed, referring to photos she received from Shannon herself.

"Right when I found out about David's affair. . .we went out to dinner," Shannon revealed, explaining that she woke up hours later nine blocks away with bruises on her knees. "I don't know if something was slipped into my drink. . .I don't remember what happened."

"Listen, she's not a nice person," Tamra responded.

Of course, when Vicki's rumors about Tamra's husband Eddie being gay came up, the fight reignited.

"Would you shut up old lady?!" Tamra screamed at Vicki, reminiscent of their bus ride brawl earlier in the season.

"You made me out like a con woman and a liar, and I did not lie!" Vicki screamed back, more shrill than ever.

Unfortunately, the 'Wives were unable to sort everything out by the end of the reunion, despite sharing their regretful behavior. Want to find out what happens next? Get updates from RadarOnline.com Online until next season!
