Tensions reportedly arose after an incident where Harmon’s dog bit a crew member, creating a divided work environment. Perrette claimed she endured “multiple physical assaults” but didn’t provide specifics. CBS later released a statement saying her concerns were addressed privately, but the details remained undisclosed.
On-screen, Abby Sciuto’s farewell was emotional. After the death of Clayton Reeves, Abby chose to leave NCIS to honor his memory by continuing his charitable work in England. While the storyline provided closure, many fans were disappointed to see her go.
Since leaving, Perrette has distanced herself from NCIS and acting altogether. She starred in the short-lived CBS sitcom Broke but later announced her retirement from Hollywood. Despite the controversy, Abby remains one of the most beloved characters in NCIS history, and her absence is still felt on the show.
