Fans adored Abby Sciuto, the quirky, gothic forensic scientist played by Pauley Perrette on NCIS. Her unique style and cheerful energy made her one of the most beloved characters on television.
So when she left at the end of season 15, viewers were stunned. On-screen, Abby resigned after an assassination attempt — but reports revealed tension behind the scenes.
Perrette allegedly clashed with co-star Mark Harmon after his dog bit a crew member in 2016. The fallout grew so intense that the two stopped filming scenes together. In her final episode, Abby said goodbye to her team — but not to Gibbs, marking a quiet and emotional end to her time on the show.
