Episode 15 of "Desperate Housewives"
s01e15 Impossible

Mike Delfino is questioned about Mrs. Huber's murder by police and is arrested. John's friend, Justin (guest-star Ryan Carnes) attempts to blackmail Gabrielle with his knowledge of their affair and becoming her new gardner---but things are not what they may seem for both in the situation. Meanwhile, Tom wants a big promotion, but Lynette fears that she'd be home alone with the kids more than ever and tries her best in discouraging him in taking the job. Also, Bree is shocked when she finds a condom---and even more so when she learns whom it belongs to when Rex admits it is not him, but their daughter Danielle. Zach Young plans a pool party for the teens on Wisteria Lane, and things get out of hand. Lastly, an unexpected person(s) comes "out" in their sexuality of being gay.
