NCIS season 18 is officially coming on CBS, but its arrival remains uncertain at the moment. Despite that, a lot of interesting stories are coming once the series returns. Moreover, some familiar faces from the past could make an appearance at some point in the upcoming installment.
There are several reasons how some of these characters could come back in NCIS season 18, though everything depends on finding the right story. One of the most notable names who could likely make an appearance is Ziva Davis, a former series regular.
Ziva's return is one of the most anticipated events in season 17. The character appears in four episodes, but it seems like a lot of stories are still worth-exploring on her end. For instance, one of the stories that should be addressed is her reunion with Tony and Tali.
This is an opportunity to learn more about what Ziva went through in the past. When it comes to her professional life, her skills could be used to help some of the characters. Perhaps, Tony might also be included once she decided to come back and help the team.
Another character that could likely make an appearance in NCIS season 18 is Tobias Fornell. The character didn't appear in the previous installment, but it's clear that there's some unfinished business on his storyline. He is Gibbs' friend and they've got history.
Moving forward, the drug trade story should be addressed -- which was first shown in the episode titled "Daughters". This particular story wasn't explored last season. And while it was referenced shortly, the story mostly focused on Ziva's return.
Delilah Fielding could also make an appearance in the upcoming installment. She is McGee's wife, who is set to be part of one of the finale episodes of season 17. Thus, when these remaining episodes air in the new season, it's very likely we'll see the character.
Her arrival could bring some fun family moments. And in terms of helping her husband, her skills could be useful to the team. Meanwhile, Young Ducky is another character that will likely be part of NCIS season 18. This character wasn't a guest star in the present-day timeline.
But despite that, some flashbacks showed how he because the person that he was. Perhaps, his appearance could happen in the 400th episode -- yet it depends on how far the story wants to go. As per CarterMatt, the series may explore Young Ducky and Gibbs' early days.
Lastly, Dr. Grace Confalone is another character that could be part of the latest installment. There's a particular storyline for her, which involves Sloane and Gibbs. Particularly, Sloane revealed to Grace about her feelings for someone -- presumably Gibbs.
Grace could be useful in moving things further between Sloane and Gibbs. In addition, the character is also a solid confidante to Gibbs. These are just some of the characters that could probably appear in NCIS season 18. But for now, it remains to be seen whether they'll indeed return or not.
