With a strong cast and compelling storylines, it's no wonder why "NCIS" has remained one of the longest-running scripted series in television history.

The main cast members tend to stick around for a while, with actors like Mark Harmon and Sean Murray being there from the beginning.

However, others know when it's time for their characters to do something else, and that appears to be what's transpiring with Emily Wickersham, who's played Eleanor Bishop since Season 11.

The Season 18 finale saw Eleanor undertake a secret mission, but it was unclear to some fans whether she would return or if this was the end.

The actress took to Instagram to clarify her departure from the series, writing, "Hangin this hat and jacket up. What a great ride it's been.
