“RHOC” Reunion Trailer: Shannon Boasts About 'Winning' in Legal Battles but Her Drinking Still Comes Under Fire

“Someone that could be awake at that blood alcohol level is someone that drinks a lot,” Heather Dubrow tells Shannon Storms Beador

There’s never a dull moment in the OC.

In the trailer for The Real Housewives of Orange County's season 18 three-part reunion, which dropped on Oct. 31, the women are putting everything on the table, and not holding back.

With Shannon Storms Beador’s drinking and Jenn Pedranti’s relationship as major topics of conversation, along with Alexis Bellino’s return to the show, the trailer kicks off with Heather Dubrow confronting Katie Ginella over their feud.

“I don't know what I have done to you, did I run over your cat?” Heather quips. “I don't know what I have done to you.”

The camera then cuts to Tamra Judge apologizing to an unrelenting Shannon, saying, “I am sorry. I knew that you were still drinking.”

“An ‘I'm sorry, but’ is not an apology,” Shannon snaps back, and Tamra replies, “There’s no but in there!”

Heather also chimes in about Shannon’s drinking, bringing up her DUI that occurred before filming for the season began.

“Someone that could be awake at that blood alcohol level is someone that drinks a lot,” Heather says.

Host Andy Cohen goes on to ask Tamra about the cease and desist letter Jenn’s fiancé Ryan sent her, and Jenn defends Ryan’s innocence after the finale revealed his business partner was indicted for an alleged gambling scheme.

“There's nothing coming Ryan's way, nothing,” Jenn reveals.

Emily Simpson, however, is not so sure of that. “You always do this Tammy Wynette thing where you’ve got to stand by your man,” Emily says to Jenn.

“I am not!” Jenn declares.

Back in the Heather and Katie drama, Heather says that “falsely accusing people is kind of your thing,” referring to the rumor Katie shared that Heather hired paparazzi to photograph her and her husband Terry at Disneyland (which Heather vehemently denies).

“That was a horrible time,” Katie replies, wiping tears from her eyes, hinting at a deeper issue going on.

Next comes Alexis, with Andy jokingly calling her by the infamous name Tamra gave her in season 7: “Jesus Jugs has been resurrected.”

When Alexis sits down, she is immediately met with backlash over her relationship with John Janssen, who Shannon had previously dated.

“Every trash can needs a lid, and John Janssen found his,” Emily says.

“Tweedledee and Tweedledum can move away,” Alexis claps back, setting Emily off.

“Don’t f---ing call me dumb,” Emily yells. “You're the dumbest girl I've ever f---ing met!”

Following her earlier apology, Tamra again discusses Shannon’s alcohol consumption, accusing her of drinking during the wellness program she attended after her DUI.

“I didn't drink during the program,” Shannon says.

“You did,” Tamra insists.

As the teaser comes to an end, Shannon and Alexis go head-to-head, with the lawsuit John filed against Shannon for a $75,000 loan being a major point of contention.

“I'm not gonna apologize for defending my man. He was still gonna sue you,” Alexis says.

“And I ended up winning, asshole,” Shannon replies.
