The great thing about a show that's already in its 21st season is that there are so many characters over the years who could come back for guest roles. And on NCIS, that includes a number of fan favorites, including one who did so in the Feb. 19 tribute to Dr. Donald "Ducky" Mallard and the late actor who played him, David McCallum.
NCIS Director Explains If Michael Weatherly Will Ever Come Back..
The episode's final scene saw Tony DiNozzo (Michael Weatherly) join Dr. Jimmy Palmer (Brian Dietzen, who co-wrote the episode) and tell him that he "wouldn't miss it for the world." The day after the episode aired, Weatherly wrote on social media that "being back… was really great" and that "Ducky would have loved all those smiles." And after that, we can't help but wonder how we might ever see him and others like Gibbs (Mark Harmon), Ziva (Cote de Pablo), Abby (Pauley Perrette), Bishop (Emily Wickersham), and more again.
Now, it doesn't have to be a tragic event to bring people together (although, this is a TV show, there probably does need to be a little drama). Below, we look at five other ways characters from the past could return, and which are the most likely candidates for each.
