For over two decades, Special Agent Timothy McGee (Sean Murray) has been the intellectual backbone of the Major Case Response Team on CBS’s NCIS—evolving from the nervous “Probie” to the seasoned, second-in-command leader. One of McGee’s most defining, and often revisited, character traits is his secret life as a successful novelist under the pseudonym “Thom E. Gemcity.”
McGee’s novels—particularly the “Deep Six” series—are thinly veiled, fictionalized accounts of the NCIS team’s adventures, complete with characters based on his real-life colleagues, like “L.J. Tibbs” (Gibbs) and “T.C. Fornell.” While the plot point has provided occasional comic relief, it represents a deep trove of meta-narrative potential that the show has yet to fully exploit.
In a recent, candid interview, star Sean Murray discussed McGee’s iconic literary career and, more tantalizingly, dropped hints about how the concept of McGee’s writing could be used in upcoming seasons to facilitate the return of beloved former cast members—most notably, Mark Harmon’s Leroy Jethro Gibbs. Murray’s insights confirm that McGee’s book isn’t just a quirky detail; it is a potential narrative device holding the keys to the NCIS past.
✍️ McGee’s Literary Life: The Power of Thom E. Gemcity
The concept of McGee’s alter-ego, Thom E. Gemcity (an anagram for Timothy McGee), provides a unique lens through which the show can reflect on its own history.
The Meta-Narrative Potential
-
Fictionalizing the Facts: McGee’s books are known for embellishing the truth—a perfect mechanism for bringing back characters whose real-life status on the show is complicated. An episode could revolve around a new “Deep Six” book that sparks a genuine investigation, or forces a character to confront an event the novel fictionalizes.
-
Murray’s Perspective: Sean Murray acknowledged the unique position of his character. McGee is the “Chronicler” of the NCIS team. Having been present since the beginning, he is the one who holds all the institutional memory, both professionally and personally. His ability to write about the team gives him an unprecedented form of narrative control—even if he doesn’t fully realize it.
The Gibbs Dilemma
McGee’s relationship with Gibbs is arguably the most foundational on the show. Gibbs was his mentor, his boss, and the closest thing he had to a father figure on the team.
-
“L.J. Tibbs” and Legacy: Any new McGee book would inevitably feature a character based on Gibbs (“L.J. Tibbs”). This serves as a constant, emotional tie to the former leader, reminding the audience and the current team of his profound influence.
-
The Emotional Arc: The exploration of a new “Deep Six” book gives the writers a safe space to explore McGee’s current feelings about Gibbs’ absence without requiring a physically present cameo—a crucial element for a show seeking to move forward while honoring its past.
🗣️ The Spoilers: Returning Cast and Narrative Devices
Sean Murray’s most compelling comments addressed the potential for McGee’s writing to serve as a narrative trigger for the return of former cast members.
The Gibbs Scenario
The question of Mark Harmon’s return as Gibbs is the perennial topic for NCIS fans. While Gibbs is alive and well, living in Alaska, a physical return to D.C. requires massive logistical planning.
-
The Book as the Lure: Murray hinted that a storyline involving McGee’s book could be the perfect “lure” or “catalyst” for Gibbs’ return. For example, a character or event fictionalized in the book could suddenly become a real-life threat or a personal issue requiring Gibbs’ unique, off-the-grid expertise.
-
Emotional Integrity: A return framed by McGee’s book would have massive emotional integrity. It wouldn’t be a random appearance; it would be a direct acknowledgment of the deep bond between the two men, forcing Gibbs to break his self-imposed exile for his former protégé.
Beyond Gibbs: The Legacy Cast
The show has a rich history of beloved characters whose returns are constantly theorized, including Tony DiNozzo (Michael Weatherly), Ziva David (Cote de Pablo), and Abby Sciuto (Pauley Perrette).
-
Fictionalized Conflicts: A McGee storyline focusing on the fictionalized adventures of “Deep Six” could involve him seeking out former colleagues to verify facts, clear up perceived betrayals, or apologize for exaggerating certain events in his novels.
-
The “T.C. Fornell” Connection: Murray specifically mentioned that McGee’s books often feature fictionalized versions of allies like Tobias Fornell. An investigation triggered by a book could easily draw Fornell back into the fold, providing a familiar and often necessary non-NCIS perspective.
📘 The Future: McGee’s Role as Leader and Chronicler
The character of Timothy McGee is currently standing at the pinnacle of his career, and his identity as an author is more significant than ever.
The Leadership and Legacy
As the senior agent, McGee is now the anchor of the team. His personal character development—marrying Delilah, becoming a father, and rising through the ranks—makes his dual identity as a writer deeply symbolic.
-
A Man of Two Worlds: McGee represents the successful integration of personal life and professional demands. His books are his way of processing the darkness of his job, turning the trauma of his cases into creative release. This makes him a vital role model for the next generation of agents.
-
The Final Chapter: As NCIS continues, McGee will inevitably be the one to write the final chapters—both literally, as Thom E. Gemcity, and figuratively, as the longest-serving member.
The Fan Demand
Sean Murray’s openness about using the book as a narrative device is a direct response to fan demand. Audiences crave continuity and a respectful handling of the show’s rich history. By utilizing McGee’s literary life, the showrunners have a sophisticated, meta way to acknowledge fan wishes while still moving forward with the current team, led by Alden Parker (Gary Cole).
🔑 Conclusion: The Key to the Past
Sean Murray’s revealing commentary on Timothy McGee’s literary career confirms that the concept of “Thom E. Gemcity” is far more than a throwaway plot point. It is a powerful narrative key that the showrunners can strategically use to unlock the past.
The possibility that McGee’s new book could serve as the perfect, organic catalyst to bring back beloved former cast members, particularly Gibbs, is the most exciting spoiler Murray delivered. It ensures that NCIS can continue its current success while respectfully honoring the foundational relationships and compelling history that McGee—the Chronicler—has documented for over two decades. The “Deep Six” series might just hold the secret to the ultimate NCIS reunion.
