Marco spent years believing his wife Delia would always put their five-year-old son, Julian, first. But on his birthday, she was busy playing mother to Damon Ricci's daughter, Piper. At a school event, Delia publicly denied Julian was her child. Heartbroken, Marco filed for divorce and returned to Miami with his son, reclaiming his place in the powerful Castellano family. When Delia begged them to return, mafia heiress Renata Falcone had already shown Julian what a mother's love could be.
