General Hospital Shocker: Marco’s World Turns Upside Down as Sonny & Carly Revealed as His Parents

Port Charles is reeling after a revelation that promises to change everything. In a heart-stopping twist, Marco discovers a letter from the late Natalia—a suicide note containing the most explosive secret in General Hospital history. As Marco reads Natalia’s final words, his world shatters: he was never her biological son. The truth is even more staggering—his real parents are Sonny and Carly Corinthos.

For years, Marco believed he was Natalia’s child, but the letter reveals a harrowing tale of loss and deception. Thirty years ago, during what was thought to be a routine birth, Carly delivered twins. While the Corinthos family celebrated Morgan’s arrival, his twin brother Marco was secretly stolen from the hospital. Sonny and Carly, devastated by Morgan’s later death, never knew they’d lost another son that night.

Marco’s entire identity is thrown into chaos. Raised by Natalia, who only recently learned the truth herself, Marco now faces the reality that he’s a Corinthos by blood. The revelation sends shockwaves through the family, especially as Marco has been working as a lawyer in Port Charles and developing feelings for Lucas—unaware of his true legacy.

As Marco struggles with the betrayal and grief over Natalia’s death, he must also come to terms with his real parents’ identities. Sonny, the man Marco has long suspected and resented, is his biological father. Carly, the woman he’s watched from afar, is his mother. Their reactions are equally intense: Sonny’s fierce protectiveness is ignited, and Carly is left grappling with the pain of losing a child she never knew existed.

This discovery doesn’t just shake Marco’s world—it ripples through every corner of Port Charles. His relationships with those he thought were family, his budding romance with Lucas, and his professional ties all take on new meaning. The revelation also threatens to unravel other secrets, casting suspicion on old enemies and raising questions about the circumstances of Morgan’s death.

Meanwhile, the Corinthos family’s already complicated dynamic is upended. With seven children and a legacy built on secrets, the addition of a long-lost twin adds a new layer of drama and heartbreak. Marco’s emergence as Sonny and Carly’s son forces everyone to confront their past choices and the lies that have shaped their lives.

But the drama doesn’t end there. As Marco seeks answers, he uncovers more about his abduction—a possible kidnapping or illegal adoption scheme that kept him hidden for decades. The people responsible remain at large, and Marco’s quest for the truth could put him in danger.

Amidst the chaos, other Port Charles families are dealing with their own crises. Lulu Spencer’s rage erupts after her son Rocco learns the truth about his birth, and Sasha and Michael Corinthos face a terrifying stalker threatening their newborn daughter, Daisy. As secrets unravel and alliances shift, every character is forced to choose sides—and some may never recover from the fallout.

In the weeks to come, Port Charles will be a battleground of emotions, betrayals, and long-overdue confrontations. Will Marco find acceptance with his true family, or will the weight of his past keep him on the outside? Can Sonny and Carly heal from decades of loss and lies? And who will pay the price for the secrets that have finally come to light?
