Josh Madden met Kendall Hart, Greenlee Lavery and Simone Torres when he caught the three breaking into his father Greg's fertility clinic to steal Greenlee's husband sperm. Josh agreed to keep the secret, but later blackmailed Kendall so that she'd use her influence with her mother, Erica Kane (Susan Lucci), to get Josh a job as a producer of Erica's new talk show.
