In the show’s third season, Tony (James Gandolfini) meets Gloria Trillo (Annabella Sciorra), another patient of therapist Dr. Melfi (Lorraine Bracco). Immediately taken with her, Tony successfully pursues Gloria as the latest of his many extramarital affairs. Despite only appearing in seven of the show’s 86 episodes, actress Annabella Sciorra delivers one of the show’s most impactful and emotionally turbulent performances as Gloria. Smart, confident and independent, Gloria is arguably the only woman Tony Soprano could conceivably have left his wife Carmela (Edie Falco) for.
Unfortunately, complications from Gloria’s personality disorder (which had caused several past relationships to erode as we learn in dialogue between Gloria and Dr. Melfi) led to a tragic end for the character. After Gloria’s jealous side begins to show, Tony cuts off their relationship completely. Fearing that Gloria will expose their affair to her family, he even orders one of his subordinates to threaten her at gunpoint.
In the fourth season, we learn that Gloria, overcome with grief, has committed suicide. It’s a heartbreaking revelation for the audience and for Tony, who is haunted by Gloria’s death throughout the series. Sciorra’s performance as Gloria earned a well-deserved nomination for Outstanding Guest Actress in a Drama Series at the 2001 Primetime Emmy Awards, and remains one of “The Sopranos’ most memorable characters.”
