NCIS is one of the few shows on television that has remained consistent throughout the years. You know what you're getting every week, and that's a solid hour of entertainment. It's the 8th longest-running scripted prime-time TV series, with 15 seasons under its belt.

Starting in 2003, NCIS follows the Naval Criminal Investigative Service and their attempts to thwart criminals.

In 2016, NCIS saw fan-favorite and original character Tony DiNozzo (played by Michael Weatherly) depart the show. His close friend, castmate Pauley Perette, says she was "dehydrated from crying so much" when she saw Weatherly leave.

But now, fans will need to prepare themselves for another tear-jerking goodbye.

After the coming season, another original cast member will be leaving NCIS.

"So, it is true that I am leaving NCIS after this season," announced Pauley Perette on Twitter. "It was a decision made last year. I hope everyone will love and enjoy EVERYTHING ABBY not only for the rest of this season but for everything she has given all of us for 16 years. ... I love her as much as you do."

After Perette's departure, there will only be two remaining original cast members: Mark Harmon and David McCallum.

At least fans will have one more season to prepare themselves to say good-bye to Pauley's character, Abby. But that doesn't mean it will hurt any less!
