It’s The End of an Era for ‘NCIS’ as Its Best Character Is Exiting the Series md20

After 20 years, NCIS may be ready to say goodbye to one of its longest-serving agents — and the show did so quietly and perfectly. In Episode 2 of Season 23, longtime fan-favorite Timothy McGee (Sean Murray) quietly set the stage for his eventual departure, giving audiences a glimpse of what his future might look like beyond the Major Case Response Team. It feels both earned and poetic and offers a fitting next chapter for the tech-savvy agent who has served as the show’s moral center throughout the entirety of Gibbs’ time on the team.

Timothy McGee’s ‘NCIS’ Evolution From Probie to Backbone of the Team

When McGee first appeared in Season 1 as a nervous junior agent, few could have guessed he’d become the longest-standing member of NCIS’s ensemble. Over the years, viewers watched him transform from an MIT-trained computer geek into the team’s calm, capable backbone. Once teased as “McGeek” and “Probie,” McGee grew into Leroy Jethro Gibbs’ (Mark Harmon) most trusted agent, and later, the senior field agent who held the team together through major transitions — from Gibbs’ retirement to the leadership of Alden Parker (Gary Cole).

McGee’s growth has always been gradual. He is a husband, a father, and a man who has long since accepted the emotional effects of his occupation. However, while McGee’s professional growth has developed in recent years, his storylines have remained dormant. After over 20 years of service, it raises the question: What can McGee do that he hasn’t already accomplished?

The answer may have arrived in Season 23, Episode 2 (“Prodigal Son Part II”). While the hour focused primarily on Parker’s pursuit of justice for his father’s murder, it also slipped in a significant detail: McGee’s “special personal project.” When he meets Parker in an off-the-grid shack, McGee unveils MooseNet — a self-sustaining communications network built with solar power, satellite internet, and what he jokingly calls “moose-enhanced Wi-Fi.” The device even has a patent pending.

At first glance, it’s a classic McGee moment — resourceful, a little dorky, but deeply competent. On closer look, it’s also the show’s way of revealing his potential exit plan. For a man who’s spent his career fighting cybercrime and hacking into impossible systems, creating a groundbreaking communications tool feels like the logical next step. MooseNet isn’t just a gadget — it’s the culmination of McGee’s expertise and independence, setting him up for life beyond the badge.

NCIS has done this before. Gibbs left for Alaska in search of peace. Abby Sciuto (Pauley Perrette) left to pursue safer, more meaningful work. For McGee, entrepreneurship might be his version of peace — a new path that still honors his legacy without killing off his character or undermining his growth.

Murray’s portrayal of McGee has been one of NCIS’s defining constants. Over 23 seasons, he’s evolved alongside the series itself — from tech consultant to senior field agent, from the “Probie” fumbling his words to the steady hand keeping a younger generation grounded. His bond with Gibbs, his mentorship of Knight, and his friendship with Torres were all a testament to what made him special.

If this is indeed a preview of McGee’s swan song, it represents a turning point for NCIS. However, it is a full-circle moment as well; it is a reminder that, when it comes to great characters, they don’t need grotesque or spectacularly choreographed exits to be impactful. In fact, the quieter departures may have the most significant impact.

With the series doubling down on Parker’s storyline and teasing fresh mysteries — including new questions about Director Leon Vance (Rocky Carroll), Torres, and the still-unresolved threads surrounding Parker’s family — NCIS is clearly preparing for another chapter of reinvention. But even as the show leans into new energy, it owes much of its longevity to characters like McGee. His departure, if it comes to pass this season, will leave a void that no recruit can quite fill.
