After seven seasons as Eleanor “Ellie” Bishop on NCIS, Emily Wickersham bid farewell at the end of season 18. Despite not officially disclosing the reason for her departure initially, Wickersham later revealed her pregnancy on Instagram, hinting at personal reasons. In the season finale, “Rule 91,” Bishop’s exit unfolded as she leaked a confidential NSA file, orchestrated by ex-CIA instructor Odette Malone. This plot twist set the stage for an undercover mission, leaving room for Bishop’s potential return. Wickersham’s departure followed other significant exits, including Mark Harmon as Special Agent Leroy Jethro Gibbs and Maria Bello as Forensic Psychologist Jack Sloane.
