NCIS star Sean Murray admits he truly believes Mark Harmon's Leroy Jethro Gibbs could return in a future episode.

CBS' hit procedural has long been one of television's most reliable performers, and that remains true even in its current run.

NCIS season 19 has brought about a number of changes to the core team, with two new members - Jessica Knight (Katrina Law) and Alden Parker (Gary Cole)

And yet, even as NCIS season 19 explores the new team dynamics and offers up plenty of twisty mysteries involving the US Navy

there is still one major character looming over the series. Harmon, who led NCIS as stoic Agent Gibbs from its very first episode in 2003

Murray, who plays probie-turned-seasoned agent Timothy McGee, thinks as much too. In a recent conversation with Parade

It remains to be seen if the upcoming NCIS season 19 finale will feature a Gibbs cameo. With the main plot revolving around his replacement, Parker, it might be better to have Gibbs sit this one out

Now that the possibility has been voiced by one of the stars, it could only be a matter of time before Harmon makes another NCIS appearance.
