Bree sabotages Edie's business by hounding off a family that wanted to move into the Young house. Orson arrives at Bree's house trying to reconcile with her, and wants to take Benjamin to a carnival, but all his apologies fail and she calls in a lawyer to sort out Benjamin's custody. Edie then goes to Orson's apartment to complain about Bree and she notices Orson's statement about Benjamin on the table. In the statement, it is revealed that Benjamin's biological parents are actually Austin and Danielle. Edie then blackmails Bree to be kind to her and do whatever she wants, or all her secrets will be exposed. Bree decides to reveal Benjamin's true parentage to Lynette, Susan and Gabrielle herself and explains Edie's attempt to blackmail her. To her surprise, the ladies understand and support Bree and march down to Edie's house and finally end their friendship with her. Edie reluctantly apologizes, but this falls on deaf ears. Edie then tells her son Travers that she will be spending Mother's Day with him as she leaves Wisteria Lane. She also promises to spend a lot more time with him from now on.
