Gretchen proposes to Slade during a stunning skyscraper rooftop rendezvous, but none of the other ladies score an invite to the engagement party that follows. Heather and Terry break the news to their kids that they've sold their home. Vicki hears Slade insult her on his radio show and plans to confront him at her upcoming "Winter Wonderland" party. As the party begins, the ladies are full of surprises: Tamra reveals her wedding date, Vicki reveals her rekindled relationship with Brooks, and everybody reveals their true feelings about Gretchen.

Andy Cohen sits down with Vicki Gunvalson, Tamra Barney, Gretchen Rossi, Alexis Bellino, Heather Dubrow and Lydia McLaughlin to revisit the drama from season eight. The epic three-part reunion begins as Vicki and Gretchen go head to head digging up the past and slinging mud as they vie for Tamra's friendship. The drama then turns to new housewife Lydia who is called to task about her outspokenness and forced to defend herself against accusations of stirring the pot. And then the tension hits a boiling point when original housewife Lauri Petersen returns to defend her claims of Vicki's infidelities instigating an explosive fight that changes the nature of their friendship forever.
