To this day, Pauley Perrette remains one of NCIS' most notable stars who will almost assuredly never film for the crime procedural again. Fans loved Perrette's portrayal of Abby Sciuto, but the actress left the series due to issues with co-star Mark Harmon. And, even after Harmon's own exit, the chances of Perrette ever returning to the series feel slim. That said, she was recently spotted at a concert with co-star Brian Dietzen, so it seems she's still tight with at least one cast member on the show.
Dietzen posted a picture with Perrette on Instagram, noting that he hung out with his former on-screen crime lab buddy at a recent show in Los Angeles. Check out the sweet photo to see Perrette (as you almost assuredly won't see her on the 2026 TV schedule):
