Pauley Perrette Reveals The NCIS Role Only Abby Could Fill

The team leader and central character of "NCIS," Leroy Jethro Gibbs (Mark Harmon), is a hard and serious man by any definition. Though he's a capable supervisor and a thoroughly decent human being, his firmness and military background means that he's not the kind of guy who suffers underlings who talk back at him ... that is, unless the person in question is Abby Sciuto. As Pauley Perrette reveals in TV Guide Magazine's "Gibbs Forever Special Collector's Edition" (via TV Insider), Abby is indeed the sole "NCIS" character who enjoys "calling Gibbs out" privileges.

"Abby is the only one who can crack back with him, like 'Gibbs, you're being crabby,'" Perrette described the chemistry between the two characters. "No one else would be allowed to."

While Gibbs and Abby were on great terms, things were unfortunately less amazing behind the scenes. According to some pretty concerning allegations by Perrette, her relationship with Harmon deteriorated after an incident involving the latter's dog, and the ensuing fear and trust issues contributed to Perrette's departure from the show.
