EVER! (Please stop asking?) I am terrified of Harmon and him attacking me. I have nightmares about it.”
At the outset of Season 15, which premiered in the fall of 2017, Pauley Perrette made the announcement that she intended to depart from the show by the season’s end. According to reports from TheWrap, Perrette and Mark Harmon, who portrayed Special Agent Leroy Jethro Gibbs, had been embroiled in issues dating back to 2016. This conflict began when Harmon’s dog bit a crew member, resulting in a need for stitches. Perrette was dismayed that the dog was allowed back on set, and the tension between the two stars continued to escalate until she ultimately made the decision to permanently leave the show.
Abby Sciuto made her last on-screen appearance on May 8, 2018, in Episode 22 of Season 15, titled “Two Steps Back.” In this episode, Abby sustains severe injuries from an attack by a hitman but manages to recover and subsequently tracks down the individual responsible for ordering the hit. Using her cunning, she coerces a confession from him. With his arrest secured, Abby resigns from her position at NCIS and embarks on a journey to England, accompanied by the body of Clayton Reeves (Duane Henry), the MI6 agent who sacrificed his life to protect her. Abby’s storyline culminates with her founding a charity in memory of Reeves, dedicated to assisting the homeless. Notably, Abby’s character did not make appearances in the final two episodes of Season 15, although Perrette’s name continued to appear in the credits.
