NCIS: Los Angeles Season 13 Episode 13 Cast: Actors and Characters Explained

NCIS: Los Angeles Season 13, Episode 13, titled “Bonafides,” features the show’s core Office of Special Projects team as they investigate a new threat. Alongside longtime favorites such as G. Callen and Sam Hanna, the episode also includes newer team members who have become integral to the series during its later seasons.

Main Cast and Characters

Chris O’Donnell as Special Agent G. Callen

Chris O’Donnell has anchored NCIS: Los Angeles since day one, shaping G. Callen into one of network TV’s most guarded yet compelling team leaders. A film star before his long CBS run, O’Donnell broke through in the 1990s with back-to-back studio hits and prestige projects, then transitioned into a steady television presence with arcs on primetime favorites before taking the NCIS: LA lead in 2009.

As Callen, he remains the quiet strategist who reads a room in seconds and outmaneuvers adversaries with patience rather than flash. Season 13 threads in the character’s complex history with covert programs and old ghosts from his formative years, which often colors his approach to midseason cases. In Episode 13, Callen’s steadiness under pressure and his ability to connect disparate clues keep the investigation on track while others juggle personal stakes.

O’Donnell’s career highlights include an Oscar-nominated ensemble in Scent of a Woman alongside Al Pacino, his turn as Dick Grayson in Batman Forever and Batman & Robin, and a memorable Grey’s Anatomy arc. Two decades later, he brings the same level of control and restraint to Callen that made those earlier roles pop, giving NCIS: LA its cool center.

LL Cool J as Special Agent Sam Hanna

LL Cool J is the franchise’s field force, blending physical presence with warm, quick-witted leadership as Sam Hanna. A hip-hop icon and seasoned actor, he brings charisma and grounded humor to every briefing and every breach. Across the show’s long run, Sam has evolved from blunt-force asset to mentor, with a protective streak that defines his bond with his partner and the younger agents.

Within Season 13, Sam balances mission focus with a deepening sense of responsibility for the squad’s next generation. His command voice often sets the tempo in the field, and in Episode 13 he serves as the team’s anchor, handling tense confrontations and delicate interviews with equal ease. The dynamic between Sam and Callen stays as sharp as ever, built on trust and dozens of close calls.

Beyond NCIS: LA, LL Cool J’s screen credits include Deep Blue Sea, In Too Deep, S.W.A.T., and the sitcom In the House. He also hosts and performs at major awards shows and remains a Rock and Roll Hall of Fame inductee, underlining a rare dual legacy as a music pioneer and broadcast television mainstay.

Daniela Ruah as Special Agent Kensi Blye

Daniela Ruah gives Kensi Blye a mix of precision, empathy, and steel. Over the series, Kensi has grown from fearless sniper to a thoughtful team pillar who trusts her instincts even when the playbook says otherwise. Season 13 continues to reflect Kensi’s knack for connecting with witnesses and victims, and her evolving perspective on family and work-life balance.

In Episode 13, Kensi’s read of a scene and her patience during interviews help unlock motivations that raw data can miss. She and Deeks remain one of network TV’s most reliable partnerships, using humor to navigate hard days and heavier subject matter that occasionally lands on their desk.

Ruah has become a creative fixture behind the camera as well, directing multiple episodes of NCIS: Los Angeles in recent seasons. On screen, her command of Kensi’s emotional gears and dry comedic timing keep the character fresh in year 13, a testament to Ruah’s range and staying power.

Eric Christian Olsen as Marty Deeks

Eric Christian Olsen’s Marty Deeks is the unit’s resident disruptor in the best sense. A former LAPD liaison with a surfer’s wit, Deeks can defuse a room with a joke, then turn on a dime when the job demands clear eyes and a firm hand. The role thrives on contrasts, and Olsen has spent years sharpening that balance between class clown and conscience.

This season, Deeks continues to ride shotgun with Kensi while bringing a people-first angle to their cases. Episode 13 taps Deeks’ capacity for empathy and his streetwise instincts, which often surface valuable leads when official channels stall. The push-pull between humor and heart remains the core of why the character lands for fans.

Olsen’s film credits include Not Another Teen Movie and Dumb and Dumberer: When Harry Met Lloyd, alongside memorable turns on network comedies and dramas. On NCIS: LA he also contributes behind the scenes as a producer in later seasons, helping shape the show’s tone as it matured.

Medalion Rahimi as Special Agent Fatima Namazi

Medalion Rahimi brings tech savvy, sharp instincts, and calm under fire to Fatima Namazi. Introduced in Season 10 and elevated to series regular in Season 12, Fatima has grown into a key operator both on screens and in the field. She provides real-time intel, cultural insight, and a readiness to roll out when the case pivots from research to pursuit.

Episode 13 continues the midseason rhythm of leveraging Fatima’s analytical skills. Whether parsing comms chatter or locking in on surveillance anomalies, she is often the one who spots the thread the team can pull. The character’s blend of competence and warmth adds an important dimension to the squad’s chemistry.

Rahimi is known for ABC’s Still Star-Crossed, with additional film and television credits spanning dramas and genre fare. Her presence on NCIS: LA has only expanded, giving the long-running series fresh energy and a modern skill set that aligns with contemporary investigations.

Caleb Castille as Special Agent Devin Rountree

Caleb Castille’s Devin Rountree is the franchise’s athletic spark, a quick study who has turned raw talent into reliable field chops. After arriving as a recurring player in Season 11 and moving to series regular in Season 12, Rountree has steadily earned larger assignments and trust from the veterans.

By Episode 13 of this season, Rountree is often running point on fast-moving pieces of an op, coordinating with Fatima and taking direction from Sam. The character’s willingness to learn, coupled with a growing confidence, keeps him central to the team’s evolving identity as it welcomes a new generation.

Castille first drew notice playing Tony Nathan in the feature Woodlawn, bringing real-life athleticism to the role. NCIS: Los Angeles has become his signature credit, highlighting both physicality and a natural rapport with an ensemble that thrives on lived-in banter.

Gerald McRaney as Retired Admiral Hollace Kilbride

Gerald McRaney lends old-school gravitas to Retired Admiral Hollace Kilbride, the no-nonsense overseer who stepped in to steady operations. Promoted to series regular in Season 13, McRaney’s Kilbride is a straight shooter who values results, accountability, and the welfare of his people, even if he expresses it with a dry, cutting aside.

In the absence of the team’s longtime operations chief, Kilbride’s leadership defines the office dynamic in Episode 13. He clears roadblocks, presses for better intel, and reminds everyone of the mission when emotions run hot. The character’s clear-eyed support has turned him into a fan favorite late in the run.

McRaney’s television legacy spans Simon & Simon, Major Dad, Deadwood, and a guest role on This Is Us that earned him an Emmy. His knack for authority figures with hidden warmth makes Kilbride an ideal fit for NCIS: LA’s late-period stride.
