Pauley Perrette’s sudden exit from NCIS in 2018 left fans confused and heartbroken. After 15 years of playing the beloved Abby Sciuto, one of the show’s most unique and adored characters, her departure didn’t feel like a typical career move. While CBS initially suggested it was simply time for her to move on, Pauley later revealed that the real reason was much deeper—and far more troubling.

In a series of cryptic tweets, Perrette hinted at “multiple physical assaults” and a toxic work environment. Though she never publicly named anyone, many fans connected her comments to long-standing rumors of on-set tension with Mark Harmon. One reported incident involved Harmon’s dog biting a crew member, which allegedly caused conflict when the dog continued coming to set. This reportedly created a divide between the two stars, who no longer filmed scenes together in their final season.

Pauley’s decision to speak out, even in vague terms, revealed just how difficult things had become behind the scenes. She expressed fear about telling the truth but made it clear that her silence was protecting the people around her. Fans were stunned to learn that such a beloved show could have such dark moments behind the camera.

Today, Perrette has stepped away from acting entirely, focusing instead on charity and personal peace. Her experience remains a painful reminder that even the most joyful characters on screen can be hiding a storm off-screen. For many, her bravery in walking away only strengthened their admiration for her.
