1. Mark Harmon – Gibbs: Gibbs, whose last appearance was in the Season 18 finale, could make a poignant return from his remote lifestyle in Alaska to bid farewell to his longtime friend and colleague “Duck.”
2. Michael Weatherly – Tony DiNozzo: Although Weatherly’s last appearance was in the Season 13 finale, his character’s connection with Ducky could make his presence a welcome fan service, especially considering Tony’s relationship with Ziva.
3. Pauley Perrette – Abby Sciuto: Abby’s last appearance was in May 2018 after 15 seasons. Given her love of science and close relationship with Ducky, her inclusion in any farewell episode would be fitting.
4. Cote de Pablo – Ziva David: Ziva’s unexpected return in Season 16 and subsequent appearances in Season 17 established her connection with Gibbs and Tony. Having both Tony and Ziva present to honor Ducky would be fitting.
5. Emily Wickersham – Ellie Bishop: While Bishop’s abrupt departure in the Season 18 finale may create closure concerns with Nick, her return could add a meaningful layer to the farewell episode.
6. Maria Bello – Dr. ‘Jack’ Sloane: Jack Sloane’s connection to Ducky’s transition and her three-season run on the show make her a fitting candidate to return and pay tribute.

The decision on which characters to include will undoubtedly be influenced by the desire to maintain the emotional impact and legacy of both David McCallum and his iconic character, Dr. Donald ‘Ducky’ Mallard.
