NCIS season 18 will deliver its 400th episode and it will explore the early days of some of the characters. Gibbs and Ducky's history, in particular, will be the center of almost everything. This is a chance to learn more about their origins, as well as some of the things they've been through in the past.

There aren't a lot of details about the upcoming NCIS season 18, aside from the fact that it will be airing the 400th episode of the procedural drama series. The episode will deliver a story about Gibbs and Ducky. Looking back from where they start in season 1, the two have developed a rapport.

Gibbs and Ducky know the weaknesses and strengths of each other, that's why they're a formidable team. So, how will their history be further explored entering the new installment? Some of the stories might be somehow complicated.

Perhaps, the 400th episode will include flashbacks to address some specific timelines. We'll probably see younger versions of Gibbs and Ducky. If ever the episode does this, we'll likely see a story about them taking on some cases from the past.

Aside from that, it could also tell present stories that would allow both of them in the spotlight. They could work in a certain case, which could lead them to look back at their history. A lot of stories could be explored here. In addition, we could also see some familiar faces from the beginning.

As for whether or not we'll see more of Ducky in NCIS season 18, nothing is confirmed at the moment. But with the filming restrictions due to the current global health crisis, CarterMatt noted the series could be more about mysteries and critical thinking -- where Ducky can come into play.

This character has historical knowledge, which is essential. He could also pass some information to Palmer even though he is not the main medical examiner. Moreover, Ducky could serve as a guide and mentor to others moving forward.

He'll be useful in NCIS season 18 compared to the recent installments. Since it's unlikely the series will bring a lot of guest stars this time around, they could rely on the series regulars. However, there are still things that should be considered here.

For instance, if David McCallum still wants to have more appearances on the series. He has taken smaller roles over the past years to spend more time with his family. Because of that, it's uncertain whether or not we'll see more of Ducky in NCIS season 18.
