Summer (Hunter King) has made it her mission on the CBS soap to seduce Billy (Jason Thompson) and get him into bed, and even has a bet going with Kyle (Michael Mealor) on whether or not she’ll succeed. Billy has previously rebuffed all of her advances, but she knows that if she can prove Phyllis (Gina Tognoni) cheated on him, he’ll be more willing to let her seduce him. She learned that her mother slept with someone when she and Billy were briefly broken up, but hasn’t yet figured out who.
