If you’ve spent any time on a Friday night over the last decade and a half watching the Reagan family pass the mashed potatoes, you know Danny Reagan is a handful. He’s hot-headed. He’s stubborn. Honestly, he’s the kind of guy who needs a partner who can essentially act as a human shock absorber.
For years, the question of Danny’s partner on Blue Bloods was basically a revolving door of talented actors trying to keep up with Donnie Wahlberg’s "bull in a china shop" energy. But most people think it was just a few people. In reality, the list is surprisingly long, and the drama behind the scenes was sometimes more intense than the cases they were catching in the 54th Precinct.
The Partner That Started It All (And Vanished)
Most fans forget about Detective DeMarcus King. Played by Flex Alexander, King was Danny’s original partner in the pilot episode. He was there one minute, and by the second episode, he was just... gone. No explanation. No goodbye.
Basically, the network decided they wanted a different dynamic. Alexander later revealed in interviews that "test groups" felt Danny needed a female partner to balance out his aggressive NYPD style. It wasn’t about skill; it was about the vibe.
Why Everyone Still Misses Jackie Curatola
Then came the Jennifer Esposito era. For the first three seasons, Detective Jackie Curatola was the definitive answer to who Danny’s partner on Blue Bloods was. She was tough. She didn’t take any of Danny’s crap. They had this shorthand that felt incredibly authentic, mostly because Jackie and Danny were so similar in their "no-nonsense" approach to the job.
But then, 2012 happened.

Esposito’s exit from the show was messy. It wasn’t a creative choice—it was a medical one. She has Celiac disease and collapsed on set. When she asked for a reduced schedule to manage her health, things went south with CBS. The network claimed she wasn't available enough; she claimed they were blocking her from working.
Jackie "retired" due to burnout in the show, but the real-world exit left a bitter taste for a lot of fans. She finally got some closure, though, returning for the Season 13 and 14 finales as a Police Chief. It was a nice "full circle" moment for those of us who grew up watching her.
The Era of Maria Baez: More Than Just Work?
After Jackie left, Danny cycled through a few "rebound" partners. There was Detective Kate Lansing (Megan Ketch), who was great but only lasted a few months before heading back to Internal Affairs. Then came Candice McElroy (Megan Boone), who was a temporary fix before she went off to star in The Blacklist.
Then, in Season 3, Episode 17, Maria Baez walked in.
Marisa Ramirez didn’t just fill a slot; she redefined the role. Baez has been Danny’s partner on Blue Bloods for over a decade. She’s the person who stuck by him after his wife Linda died. She’s the one who gets invited to the occasional Sunday dinner (a huge deal in the Reagan world).

The "Will They, Won't They" Problem
Fans have been screaming at their TVs for years for these two to just get together already. The chemistry is obvious. They’ve survived shootings, kidnappings, and Danny’s terrible mood swings.
In the series finale, "End of Tour," we finally got something. It wasn’t a big Hollywood kiss. It was Danny asking, "Do you want to get a pizza?"
It sounds small. But for Danny Reagan, that was everything. It was him finally following his grandfather Henry’s advice to stop being a "perpetual bachelor" and actually bring the job home to someone.
The 2026 Update: Boston Blue and Lena Silver
If you thought the story ended when the original show wrapped up in late 2024, you’ve missed the biggest twist. The franchise didn't die; it moved.
With the launch of the spinoff Boston Blue, Danny Reagan has relocated to Massachusetts to deal with some family issues involving his son, Sean. This means he has a brand-new partner: Detective Lena Silver, played by Sonequa Martin-Green.

How Lena Silver Changes the Dynamic
- A Different Pedigree: Lena comes from a "police royalty" family in Boston, much like the Reagans in New York.
- A New Conflict: Unlike Baez, who often acted as Danny’s conscience, Lena is a "rising star" who might have her own ambitions that clash with Danny’s old-school methods.
- The Baez Connection: Don’t worry, Maria Baez isn't gone. She’s actually recurring in the new series, and the premiere confirmed that she and Danny are officially a couple. It’s a long-distance relationship (only a four-hour drive, right?), but it’s the "Daez" endgame everyone wanted.
All of Danny's Partners: A Quick Review
If you're trying to keep track, here is how the partnership history actually shakes out:
- DeMarcus King (Pilot): The one the test audiences didn't want.
- Jackie Curatola (Seasons 1-3): The fan favorite whose exit was a total scandal.
- Kate Lansing (Season 3): The IA detective who didn't want to be there.
- Candice McElroy (Season 3): A brief stop on the way to other shows.
- Maria Baez (Seasons 3-14): The partner who became the girlfriend.
- Lena Silver (Boston Blue): The new chapter in a new city.
Real-World Insights for Fans
If you're looking to dive deeper into the world of Danny's partner on Blue Bloods, you should keep an eye on a few things. First, watch the Boston Blue episodes carefully—the writers are dropping tons of Easter eggs about Danny's life in New York.
Also, it’s worth checking out Jennifer Esposito’s memoir or her recent interviews. She’s been very vocal about how the industry treats chronic illness, and it puts her departure from the show in a completely different light. It wasn't just "creative differences."
If you want to see the best of the Danny/Baez era, go back and watch "Partners" (Season 5, Episode 3) or "Common Ground" (Season 8, Episode 3). Those episodes really highlight why Marisa Ramirez was the perfect foil for Donnie Wahlberg's intensity.
To stay current, make sure you're following the official Boston Blue production updates. Since Marisa Ramirez is only "recurring" right now, fan demand is the main thing that will bring her back as a series regular. If you want more "Daez," you've gotta make some noise on social media.
