Another "Sonja" showdown is in store for viewers in the upcoming episode of "The Real Housewives of New York" season 9.

Titled "The Etiquette of Friendship," next week's episode will see Dorinda Medley finally confront Sonja Morgan. According to the official synopsis, Ramona Singer's dinner party in The Hamptons continues. Just a few moments after the event started, Dorinda takes the conversation to another level and confronts Sonja due to her incessant trash talking. 

Carole thinks Ramona is not taking the presidential election seriously, so she disinvites her from her Election Night party. Tinsley Mortimer goes out with Luann de Lesseps and Dorinda for some drinks, but decides to leave out her roommate Sonja.

Bravo released a new preview for the episode and it features Dorinda and Sonja's first confrontation since their season 8 reunion battle. It seems Dorinda has had enough, so she goes after Sonja in the reality show's next episode. "It's not going to go any further," Dorinda declared. "Do you hear me? It's not—"

Sonja immediately cuts her off and fires back. "What are you going to do? Back it up from me?" she asked her furious co-star, referring to an infamous Dorinda moment last season.

Dorinda and Sonja were at odds in season 8, and their conflict reportedly stemmed from the former not inviting the latter to the Berkshires. Next week's "RHONY" will also see Dorinda accuse her co-star of "getting vaginal rejuvenation," surprising all the ladies in the room. "We all know what kind of s—t goes down in that townhouse," Dorinda snapped back at Sonja.

The straw that broke the camel's back for Dorinda was Sonja's alleged malicious Facebook post about her. In the third episode, Dorinda said she was also able to dig up Sonja's dark secrets, hinting that she will reveal everything she knows soon.

"The Real Housewives of New York" season 9 airs every Wednesday night at 9 p.m. EDT on Bravo.
