The son of feared mob boss Carmine Falcone (John Doman), Carpinello’s Mario has rejected his family’s criminal ways and made a legitimate life for himself as a well-respected, Ivy League-educated ER doctor. He’s kind, honest and trustworthy, making him the black sheep of the Falcone clan. But — and here’s where the official character description gets interesting — his arrival in Gotham will create major waves in the personal life of Jim Gordon, who at the end of Season 2 left town to find and win back his pregnant fiancee Lee.
