In the Reunion Part One, the women gather with Andy Cohen to discuss the year, settle old scores, and clear the air. . .but Adrienne Maloof's decision not to attend sparks the initial controversy -- and leads to a shocking announcement. Other surprises are revealed in this hour: Yolanda felt unwelcome when she joined the group, Taylor admits to drinking too much, and Lisa and Kyle's touchy relationship becomes even more dramatic when Yolanda, Kim, and Brandi step in with their take on the battle.

The Bravo vaults are opened and the audience is treated to never-before-seen footage of the Housewives both at the Reunion and out-and-about in Beverly Hills. Kyle takes a nervous Lisa for her first mammogram; Yolanda and Brandi's friendship is explored in further depth, and Taylor has a meltdown directed at her onetime friend Adrienne. And in unseen footage from the reunion, the ladies discuss the actions of Faye.
