On screen, they were like family. But behind the scenes… something was deeply wrong.
During Pauley Perrette’s final season as the beloved Abby Sciuto on NCIS, a quiet storm was brewing. It all began when a dog—reportedly belonging to one of the lead actors—bit a crew member on set. While some brushed it off as an accident, Pauley saw it as a serious safety issue.
Insiders say tensions quickly grew between her and longtime co-star Mark Harmon. What started as a disagreement turned into a total breakdown. In her last season, fans noticed something odd: Abby and Gibbs never shared a single scene together.
After leaving the show, Pauley posted cryptic messages online, hinting that she had experienced “horrifying things” on set—but she never named names.
CBS later said the matter was “resolved,” but the full truth has never come out. Years later, fans are still wondering: What really happened behind the scenes of NCIS?
