Pauley Perrette, who played fan-favorite Abby Sciuto on NCIS, left the show at the end of Season 15 due to a falling out with series lead Mark Harmon. Reports suggest that the two had several clashes after Harmon's dog bit a crew member on set. Pauley did not share the screen with Harmon in her emotional final episode and bid farewell to her other colleagues instead. Following her exit, she posted vague tweets referencing the incident and physical assaults she claimed to have experienced while protecting her crew members. CBS released a statement saying they took workplace concerns seriously and worked to find a resolution. Pauley did not pursue television work but starred in the CBS sitcom Broke, which was cancelled after one season. In 2020, she announced her retirement from acting.
