Season 13 of "NCIS" will continue to be a time of change in the lives of many of the show's main characters over the next several weeks.

Fox New reports over the next two episodes, Tony DiNozzo (Michael Weatherly) and Ellie Bishop (Emily Wickersham) find themselves wondering if they made the right calls in coming to decisions that largely account for the courses their lives have taken.

For DiNozzo, that comes in the form of coming face-to-face with ex-girlfriend Jeanne Benoit (Scottie Thompson) and no doubt wondering what might have been.

Now married to a doctor volunteering in Sudan, Benoit desperately needs the help of her ex and McGee (Sean Murray) in tracking down her husband after he and others are held hostage by a group of crazed bandits.

"It is a huge episode and it sends our team off to assist and rescue a group of doctors who are in trouble," said show-runner Gary Glasberg. "It's part of a Doctors Without Border organization. And Jeanne, who is a doctor, is connected to them. This is the continuing 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."

The episode also witnesses the return of Dr. Cyril Taft (Jon Cryer) when Gibbs' (Mark Harmon) recovery hits an unexpected hurdle.

In the Nov. 17, "A Day in Court" episode, Bishop reevaluates her live and her marriage to Jack after things between them quickly began to deteriorate.

According to TV Guide, the episode is also highlighted by a petty officer's relentless pursuit to clear his name after a murder case is dismissed over shabbily handled evidence. In tine, the officer even volunteers to be court-martialed, provided the "NCIS" crew will handle the investigation.
