Oh, boy, oh, boy. As we left the cast of “The Secret Life of the American Teenager” at the end of season two, Ricky and Amy became parents. They’re what, 15? 16? I’ll be honest: as the dad of a teenage son, I’m not sure how I feel about this show, what with its frank and gentrified presentation of sexually active kids and way too understanding parents. But not every show is for everybody. And I appreciate that. And in that spirit, I’m delighted to welcome two young and talented stars from ABC Family’s “The Secret Life of the American Teenager,” Daren Kagasoff and Megan Park, Ricky and Grace, respectively.
