 Uber-mom and control freak Maisy Gibbons returns, and her secret life of being a call-girl intersects with Bree s when she finds out that Rex is cheating on her after he has a heart attack, and Bree unleashes her inner "woman scorned". Meanwhile, Gabrielle s financial predicament worsens as she gets a taste of her own medicine, courtesy of Carlos s jail house confession. Susan plans to take her relationship with Mike to the next level, and Lynette, suspicious (and a little jealous) of her new nanny Claire, decides to secretly videotape her of her interaction with the kids. Also, Susan betrays Julie when she learns that Julie is hiding Zach after he escapes from a clinic hospital, and she has Mike send Zach Young back home to his father, who makes a startling admission of his own.
