"Frame-Up" - When Tony   is accused of murder, Abby (Pauley Perrette) questions her faith in her science and her ability as a specialist while trying to prove Tony's innocence and find out who's attempting to frame him, on NCIS, scheduled to air on the CBS Television Network.Photo: Cliff Lipson  / CBS� 2005 CBS Broadcasting Inc. All Rights Reserved.Season # 003;  Production #055All good things must come to an end. "NCIS" after playing NCIS Forensic Specialist Abby Sciuto from Season 1 to the currently airing Season 15.

She also took a shot at some false rumors about her exit.

Abby is a popular original character, and she has been in fans' lives since Season 1. So even though she will apparently still be around for this 2017-2018 season, and we don't even know yet if CBS will renew the show for a 16th season, fans were very upset at Perrette's news.

At this point, Perrette is one of only three remaining original cast members, including Mark Harmon as Gibbs and David McCallum as Ducky. Fittingly enough, the next episode of "NCIS" Season 15, Episode 3, is titled "Exit Strategy." Here's the synopsis:

"Torres' partner mysteriously vanishes, and the subsequent investigation leads to new evidence in a decade-old murder; Ducky's friend presents him with a new opportunity during his guest lecture series."

That episode airs Tuesday, October 10 on CBS.
