'NCIS' Season 13 Plot News: More Changes to Come

More changes are expected to take place for the rest of the season for the series "NCIS."

The previous season of "NCIS" had Gibbs, played by Mark Harmon, shot. With that, the recent episodes have shown the aftermath of this incident. Another change that the season introduced was the marriage of Ellie, played by Emily Wickersham.

According to FOX, there are still more to come for the upcoming season. Executive producer of the series, Gary Glasberg, shared some details about the episodes to come during an interview.

He explained that the next episode of the series is expected to bring Ducky. It was said that he will be a member of a secret society that is headed by a new character played by Jessica Walters. It was revealed that the secret society works together to solve several cases.

Glasberg explained, "I don't know if it is as much a secret society as it is a small group of slightly eccentric civilians, who like to get together in the wee small hours, and take on cases that others have forgotten about. Ducky initially gets involved [with the Sherlocks] as a means of socializing and getting out a bit."

In addition, another future episode is expected to see the return of Scottie Thompson's character. It was reported that Jeanne Benoit will be returning to the series. Glasberg teased that the episode will be vital as it will put their group to help out a group of doctors.

Glasberg said, "It's part of a Doctors Without Borders organization. And Jeanne, who is a doctor, is connected to them… This is the continuing of the evolution of Tony DiNozzo. If you go back and you look at significant loves that have gotten away in his lifetime, Jeanne was one of them."

"NCIS" season 13 airs on CBS every Tuesday.
