Pauley Perrette, known for her role as Abby Sciuto on NCIS, has stated that she will never return to the show. Perrette left the series after a disagreement with Mark Harmon, who plays Leroy Gibbs, over his dog’s presence on set. Despite an oral history acknowledging the incident, no further details were revealed. Perrette, who retired in 2021, has since appeared in the NBC sitcom Broke. With the recent death of David McCallum, who played Ducky, the likelihood of Sciuto returning seems slim. Perrette’s departure and subsequent statements suggest a strained relationship with the NCIS team, making a reunion unlikely.
