In the “NCIS” Season 15 episode airing next week, an old friend of Ducky’s (David McCallum) will offer him a new opportunity. Very little details on what Cadence Darwin (Susan Blakely) will be offering, aside from it being as a guest lecturer, but speculations say that the medical examiner might consider changing careers. This means that he may have to resign from the NCIS.

The promo for “NCIS” Season 15 episode titled “Exit Strategy” shows Ducky giving a lecture in front of a group of people. He can be seen operating an old-fashioned projector while telling his audience that dead people have their ways of communicating with the living.

The synopsis has left fans wondering if McCallum will be leaving “NCIS” Season 15. His co-star Pauley Perrette recently announced in her Twitter account that the current season will be her last for the long running CBS show. According to her, she has made the decision since last year. The actress, who plays Abby Sciuoto, has been with the show since the first season.

Perrette is the third fan favorite cast member to exit from the successful series in four years after Michael Weatherly in 2016 and Cote de Pablo in 2013 reports TV Guide. Perrette said that there have been all kinds of false stories about her exit and joked, “NO I DON'T HAVE A SKIN CARE LINE AND NO MY NETWORK AND SHOW ARE NOT MAD AT ME!”

In the same “NCIS” Season 15 episode airing on Tuesday, October 10, Torres (Wilmer Valderrama) will be searching for his partner who suddenly goes missing while on a stakeout with Metro P.D. The search for Torres’ partner will lead the NCIS team to another case reports Spoilers Guide.

New evidence will surface about a murder that happened ten years ago in the course of their investigation. Meanwhile, another young boy will go missing. The team must catch the perpetrator soon if they want to stop more blood to be spilt.
