Katherine is seeing a psychiatrist, but Lynette won't see a couples' therapist. Meanwhile, Gaby and Susan are determined to find out if their kids are in the smartest group at school; and Angie disapproves of Danny's new girlfriend.

Robin turns heads (and makes a friend in Katherine) when Susan invites her home. The ex-stripper gives seduction tips to Bree, who wants to reengage Orson. And Gaby thinks Robin can help out with the troublesome Ana. But Lynette is wary. She has teen boys at home.
