Pauley Perrette’s departure from NCIS in 2018 shocked fans, but the real reason behind her exit is even more surprising. While many assumed she simply wanted to move on, Perrette later revealed that behind-the-scenes conflicts played a major role. She claimed she left due to workplace issues, hinting at serious tensions with co-star Mark Harmon.

Reports suggested that the situation escalated after an alleged on-set incident involving Harmon’s dog, which reportedly bit a crew member. Perrette was said to have felt unsafe and spoke out about mistreatment, leading to a breakdown in their working relationship. Despite CBS acknowledging the situation and wishing her well, it became clear that she would never return to the show.

Perrette has since moved on from NCIS, but her exit remains one of the most dramatic in the show’s history. Fans continue to debate what really happened, but one thing is certain—her portrayal of Abby Sciuto will never be forgotten.
