New Character Shakes Up the Franchise—What Does This Mean for Fans of Harry Bosch?
By Emily Foster, Senior TV Reporter
LOS ANGELES —
The highly anticipated return of The Lincoln Lawyer for its fourth season has already sent fans into a frenzy, but the biggest shockwave to hit the Lincoln Lawyer universe may not just be the cases Mickey Haller (played by Manuel Garcia-Rulfo) takes on—it’s the introduction of a brand-new character meant to fill the gap left by the absence of Harry Bosch. As the series shifts its focus, fans of the popular Amazon Prime Video series Bosch are eager to know how this new character will shape the dynamics and whether it could lead to a bigger crossover down the line.
For years, The Lincoln Lawyer and Bosch shared a quiet connection through their creator, Michael Connelly, and his intertwined series of novels. While Bosch focused on the gritty world of Los Angeles homicide detective Harry Bosch, The Lincoln Lawyer followed defense attorney Mickey Haller, who is also based in Los Angeles. The two characters have long coexisted in Connelly’s fictional universe, but with the end of Bosch’s TV series and the new direction The Lincoln Lawyer is taking, things are bound to change.
🔍 THE BIG QUESTION: WHO IS BOSCH’S REPLACEMENT IN SEASON 4?

With Harry Bosch (played by Titus Welliver) absent from The Lincoln Lawyer universe after the end of Bosch: Legacy, the producers of The Lincoln Lawyer had to find a way to keep the gritty detective spirit alive in Mickey Haller’s world. Enter Detective Santiago Guzman, a seasoned LAPD detective who is set to play a crucial role in The Lincoln Lawyer Season 4.
“We knew we needed someone to step into that investigative role that fans were used to with Bosch,” said showrunner David E. Kelley in an exclusive interview. “Harry Bosch was a major influence on Mickey’s world, so we wanted to introduce a character who could carry that investigative weight while still offering something fresh to the narrative.”
Detective Guzman, portrayed by Joaquín Cosío, is a no-nonsense detective with a reputation for solving the most difficult cases in Los Angeles. He shares a strong professional rapport with Mickey, and their collaboration adds depth to the upcoming season’s storyline.
🔄 Guzman’s Role and Chemistry with Mickey Haller
While Harry Bosch was a lone wolf who worked independently of the system he’d sworn to uphold, Guzman is more integrated into the LAPD’s framework. His approach to solving crimes is methodical, and he often finds himself clashing with Mickey’s unorthodox methods. However, the two share mutual respect as they team up to investigate a high-stakes case that will take them deep into the criminal underworld of Los Angeles.
“Guzman is a bit more grounded in his methods, and that’s something Mickey has to adjust to,” Kelley explained. “We wanted a character that could provide a contrast to Mickey’s sometimes chaotic style, yet someone who could still bring a sense of authority and professionalism to the table. Guzman brings that balance.”
For those who have followed the Bosch novels and the Bosch TV series, the absence of Harry Bosch will undoubtedly be felt. However, Kelley insists that the addition of Detective Guzman serves as a natural progression for the show, allowing Mickey to grow in new directions.
“Harry Bosch was an iconic character, but Mickey Haller is his own man. The introduction of Guzman doesn’t replace Bosch, but it shifts the dynamic. Mickey can’t always rely on Bosch’s help anymore, and that opens up a new chapter for him,” Kelley added.
⚖️ WILL THE BOSCH AND THE LINCOLN LAWYER UNIVERSES CROSS OVER?
While Harry Bosch won’t be appearing on-screen in The Lincoln Lawyer Season 4, many fans are wondering if the two shows might eventually cross paths. There’s no official word yet on whether Titus Welliver will reprise his role as Bosch in The Lincoln Lawyer, but Kelley hinted that the possibility of a crossover event isn’t completely out of the question.
“The worlds of Bosch and Mickey Haller are still very much connected through Connelly’s books,” Kelley said. “We’ve always been open to exploring crossover moments, and while there’s no definitive plan right now, we’re not ruling it out. Fans will just have to wait and see what happens down the road.”
Given the success of both shows and their shared universe, the potential for a crossover event could excite fans who have been following both franchises for years. Whether it’s a one-off appearance or a more significant team-up remains to be seen, but the prospect is something that has captured the imagination of fans.
📈 THE IMPACT OF A NEW CHARACTER ON THE FRANCHISE

The introduction of Detective Guzman is part of a broader evolution for The Lincoln Lawyer. As the show enters its fourth season, the character’s role as Bosch’s spiritual successor is critical not just for the storylines but for the future of the show itself. While The Lincoln Lawyer has always been a character-driven show about Mickey Haller, the addition of Guzman could help expand its scope and add layers to Mickey’s character.
“Mickey is always the focal point of our series, but in order for him to continue evolving, we need strong supporting characters,” Kelley explained. “Guzman provides that, and as the season unfolds, you’ll see how their relationship deepens and how each character challenges the other.”
For fans of Connelly’s universe, the upcoming season promises more action, drama, and suspense, but also the introduction of a new investigative voice that will help drive the series forward.
🚨 WHAT ELSE TO EXPECT FROM SEASON 4?
Season 4 of The Lincoln Lawyer will bring new cases and, of course, more twists and turns. With Detective Guzman now firmly embedded in Mickey’s world, viewers can expect an even deeper dive into the criminal world of Los Angeles. The season will also explore Mickey’s growing responsibilities, both as a lawyer and as someone who’s attempting to maintain his moral compass in a world rife with corruption.
“It’s going to be a wild ride,” Kelley teased. “We’ve got some huge twists, and Mickey is going to be pushed to his limits. But this new dynamic with Guzman is going to add a lot of fresh energy to the show.”
Fans can expect an intense season filled with suspense, character development, and more of the sharp legal drama that made the series a hit in the first place.
