Xanax Smoothies, Cocaine Accusations, Pantygate! 3 Biggest Jaw-Droppers From 'Real Housewives' Hong Kong Trip

It was one of the most insane episodes in franchise history, filled with fights on fights on fights as Erika Girardi went off on both Dorit Kemsley and Eileen Davidson and Lisa Rinna put her expert pot-stirring ways to use with explosive results.

Here are the 3 moments that had us going "Did that just happen?"

What started as an argument between Lisa Rinna and Dorit Kemsley regarding Rinna's Xanax smoothies turned into a full-blown verbal brawl. Erika Girardi chimed in, and gears quickly shifted from Lisa's problems with Dorit to Erika's problems with Dorit.

"Sometimes you just gotta let people know just how full of shit they really are," Erika said in a confessional. "I guess now's the right time."

Erika accused Dorit of "dying for her attention" and validation. "You're not interesting, you're not fucking fun at all, you're not fucking nice at all," Dorit shot back. "You're cold as fucking ice and stoic. Why the hell would I be vying for your attention?"

"Do you think I'm really gonna like you after everything that happened with the underwear?" Erika responded. "You took something that was innocent on my behalf and you turned it into a whole, 'Oh, she's doing it on purpose.'"

Yep, Pantygate just won't die.

The feud continued at another dinner, as Erika accused Dorit and her husband PK of making her look like a whore for flashing her lady bits instead of putting some of the blame on PK for looking. The only way Erika said she'd ever forgive her co-star: Dorit had to apologize to Erika's husband, Tom, and have her other half do the same.

In an attempt to smooth things over between Erika and Dorit, Eileen said "She didn't kill your child" to Girardi. This set off an epic meltdown from Erika, whose son is a police officer.

"I'm saying [Dorit] didn't commit some horrible, heinous crime," Eileen said, before trying to apologize endlessly. Erika wasn't having it.

"Eileen, your kid doesn't put on a uniform every night and put his life out on the line for people he doesn't know," she said through tears. "Don't ever talk about my kid again. Shut the fuck up."

Kyle Richards' face through this extremely heated exchange said it all.

With everyone already at odds with each other, Rinna saw it as the perfect opportunity to keep stirring the pot, making one final explosive accusation about Dorit's behavior at a recent dinner party.

"What I wanna know is when I was at your dinner, you all got up and left," Rinna said. "Everyone said, "Dorit, you need to get touched up.' And you all left at the table. Why?"

A half-confused Dorit said, "We do that after we're done with dinner."

That's when Rinna blurted out, “Were people doing coke in your bathroom? All you have to say is no." Yep, she went there. Dorit emphatically replied "No," but the latest dinner from hell will surely continue next week.
