We already know that the milestone 400th episode will focus on Ducky and Gibbs’ relationship over the many years of their friendship, and NCIS is an ensemble series.
I’m just hoping that the show takes advantage of the opening to develop characters and relationships more in the Season 17 timeline before moving beyond in 2021.
Of course, NCIS has plenty of relationships that are intriguing without romance, and I fully expect Bishop/Torres and Gibbs/Jack to be enjoyable even if sparks don’t fly more than usual to start Season 18.
