SUMMARY

  •  NCIS season 21 will explore Tim McGee’s family tree, revealing that he has more relatives than he realized.
  •  McGee’s missing mother may become the central focus of the season, delving into her story and why she hasn’t been present in McGee’s life.
  •  Despite being on the show for over two decades, NCIS continues to come up with intriguing storylines for its characters, such as McGee’s deep dive into his family’s lineage.

NCIS season 21 has an unexpected story arc for Tim McGee, co-showrunners Steven D. Binder and David North tease. After a couple of heavy season openers, which include a tribute episode to medical examiner-turned-historian Ducky, the CBS procedural will stabilize with its weekly cases. Intertwined with it are personal plots for its special agents. For McGee, that means a look at his family tree, which has some big secrets.

Speaking with TVLine ahead of its NCIS season 21 premiere, Binder and North previews McGee’s family-focused storyline, which will dig into the members of the clan that he never knew existed. It’s unclear if it’s going to be part of a case, but something must happen to convince him to check out his lineage. Read the showrunners’ quote below:

All of our characters on NCIS know that family is more important than anything. But after McGee takes a genealogy DNA test, he’s shocked to find out he has more family than he realized.

McGee’s NCIS Season 21 Arc Can Explore His Final Missing Story

NCIS season 21 will be without an original character, a first for the series. Ducky is the final cast member to star from the very first episode to his final one before David McCallum’s death. McGee did debut in season 1, but he didn’t appear until after several episodes. With Ducky now gone, he officially becomes the oldest cast member who is still active in the show. Despite being in it for more than two decades, however, certain aspects of his personal life haven’t been explored — including his relationship with his mom.

Unlike his dad, who appeared in the police procedural, McGee’s mother has never been a presence in NCIS. There’s even confusion as to where she is and why she doesn’t seem to be in contact with her son. There are assumptions that she is dead, but there’s no concrete proof of that. Other theories include her splitting with his dad and re-marrying. Whatever the case may be, considering McGee’s personal arc for NCIS season 21, delving into his missing mother’s story may be the central focus of the outing.
