All season long, newbie Real Housewives of Beverly Hills star Erika Girardi has handled herself with remarkable restraint, especially considering the insanity that's gone on around her as the rest of the ladies have been at war over who said "Munchausen's" first. But in tonight's conclusion to season six's three-part reunion special, that's all going to change.

In a sneak peek of the episode, exclusive to E! News, host Andy Cohen steers the conversation to Girardi's mid-season rift with fellow newcomer Kathryn Edwards after Kathryn ratted Erika out to Lisa Vanderpump over that whole "spinning a web" comment. As Kathryn squirms in her seat, trying to explain why she did what she did, she admits, "In hindsight, I should've stopped you when you were saying the things you were saying and said I didn't like that."

"Or you could've just kept it and not said anything," Erika quickly responds, having none of it.

From there, Erika's off to the races. We're not going to spoil just how she cuts Kathryn down to size—we'll leave you to discover that joy on your own when you watch the clip above—but prepare yourself for Erika to lob a meaty accusation of trash talk right back at her frenemy. We can't wait to see Kathryn try to talk her way out of this one.

Beyond tonight's big showdown between the pair of newcomers, tonight's reunion conclusion will also see the ladies relive their trip to dramatic trip to Dubai, with LVP and Lisa Rinna remaining at loggerheads over their never-ending feud. Also, they'll all be thrown for a loop with former Housewife Brandi Glanville appears via video to offer her thoughts on the season. Brace yourselves.
