Williams explained to Entertainment Weekly, "[Betty] had her son in chains in the basement. It was like, 'Really? Do we have to go there with our first Black character?' I honestly fell off the show after that. I think it was just so implausible and just an image that Black folks don't want to see their child chained and shackled in the basement." Cast member Felicity Huffman commented on Williams' addition to the cast, saying "She's such a great dash of vinegar to Wisteria Lane! It's going brilliantly—she's a wonderful woman, she's really smart, she's really strong, a real team player. She's a great addition." The episode also reintroduced the storyline of Paul Young and Felicia Tilman's rivalry. Mark Moses returned to the series as a series regular after appearing briefly as Paul in the sixth season finale. On his return, Moses commented, "There was some talk about [me coming back] a year ago. And there’s often talk in Hollywood. Sometimes it pans out, sometimes it doesn’t. I don’t get super-excited about a 'maybe' in this town, because there are lots of maybes that don’t happen. But then this last year they called up my agent and said, 'We're really thinking seriously about [this].' And eventually, they made an offer, and I was very pleased." Harriet Samson Harris also returned to reprise her role as Felicia, while Steven Culp and Christine Estabrook returned as Rex Van de Kamp and Martha Huber respectively in flashback sequences. Kyle MacLachlan, who left Desperate Housewives as a series regular at the end of season six, reprised his role as Orson Hodge in this episode. Kevin Rahm and Tuc Watkins, who have been portraying gay couple Bob Hunter and Lee McDermott since the series' fourth season, were both promoted to series regulars for the seventh season. Darcy Rose Byrnes also joined the main cast as Penny Scavo, a role previously portrayed by Kendall Applegate. Brian Austin Green made his series debut in the episode as Keith Watson, "a new contractor and charming playboy" who catches the attention of both Bree and Renee, while Lainie Kazan began a multi-episode guest appearance as Maxine Rosen, Susan's landlady.
