When NCIS introduced McGee’s teenage son Mateo earlier this season, it instantly added a new emotional layer to his character. However, the storyline was soon overshadowed by the shocking death of Director Leon Vance.
Now, the series is circling back to that unfinished chapter.
Patrick Keleher is set to reprise his role as Mateo before Season 23 wraps up, signaling that the writers are ready to dive deeper into one of the season’s most personal storylines. Recent episodes have already shown McGee struggling to connect with his son, underlining the challenges of their unexpected reunion.
With only a few episodes left—and a major two-part story involving Sam Hanna coming first—Mateo’s return could be key in shaping McGee’s journey moving forward. Fans can expect some emotional and meaningful development between father and son very soon.
