Honestly, if you ask a casual fan when the Nine-Nine really hit its stride, they might point to the early pilot energy or the later move to NBC. They’re wrong. Brooklyn Nine Nine Season Four is where the magic actually happens. It’s the year the writers decided to get weird, get political, and somehow make us care about a witness protection program in Florida for three full episodes.
It was a gamble.
Opening a sitcom season by yanking your two lead characters away from the precinct is usually a "jumping the shark" moment. But seeing Jake and Holt as "Larry" and "Greg" in Coral Palms? Absolute gold. It set a tone for the rest of the year that felt braver than anything we’d seen in the first three seasons.
The Florida Arc and the Risk of Change
Sitcoms are built on the status quo. You want the characters in the same office, at the same desks, making the same jokes. Brooklyn Nine Nine Season Four threw that out the window immediately. Jake and Holt are stuck in Florida, hiding from Jimmy "The Butcher" Figgis.
Jake has bleached hair. Holt is power-walking. They are miserable, and it’s hilarious. This arc proved that the show didn't need the precinct to be funny; it just needed the chemistry between Andy Samberg and Andre Braugher. When the rest of the squad eventually defies the direct orders of Captain C.J. (played with incredible vacant-eyed energy by Ken Marino) to go save them, it solidifies the "found family" theme that defines the series. It wasn't just about jokes anymore. It was about loyalty.
Why "Moo Moo" Changed Sitcom History
We have to talk about the episode "Moo Moo." It’s arguably the most important half-hour in the entire show's run. Terry Crews’ character, Terry Jeffords, is stopped by a fellow police officer while walking in his own neighborhood at night. Why? Because he’s a Black man in a hoodie looking for his daughter’s blanket.
Most sitcoms handle "issue episodes" with the grace of a sledgehammer. They feel preachy or disconnected. "Moo Moo" felt different because it stayed true to the characters. Captain Holt, a man who spent his career fighting for progress from within a broken system, initially advises Terry not to file a formal complaint. He’s worried about Terry’s career. It’s a nuanced, painful look at how systemic racism exists even among "the good guys."

There are no easy answers provided. Terry files the complaint. The other officer isn't fired; he just gets a "talking to." It’s realistic. It’s frustrating. And it showed that Brooklyn Nine Nine Season Four had the teeth to handle the reality of policing in America while still being a comedy.
The Rise of the Supporting Cast
This was the season where the "side" characters became the main event. Think about Gina Linetti. This is the season where she gets hit by a bus. Literally. It’s one of the most shocking and absurd cliffhangers in TV history.
- Charles Boyle goes full "Papa Boyle" and his obsession with Jake’s life reaches new, terrifying heights.
- Rosa Diaz starts to show cracks in her tough exterior, particularly during the high-stakes finale.
- Amy Santiago finds her footing as a leader, even when she's stressed about her relationship with Jake.
And we can't forget the guest stars. Maya Rudolph as the U.S. Marshal in Florida? Perfection. Jason Mantzoukas returning as Adrian Pimento? Pure, unadulterated chaos. Pimento is a character that should not work. He’s too loud, too crazy, and too dark. Yet, in the ecosystem of the Nine-Nine, he’s the perfect foil for everyone else’s neuroses.
The NutriBoom and Tactical Transitions
If you pay attention to the pacing of Brooklyn Nine Nine Season Four, you’ll notice it’s faster. The jokes-per-minute count is staggering. But it also started planting seeds for long-term arcs. This is where we see the beginning of the end for some characters and the evolution of others.
One of the funniest running gags involves the pyramid scheme NutriBoom ("Boom! Boom!"). It’s a subtle commentary on corporate cult culture that the show would revisit later, but it started here. It’s that kind of world-building that makes the show rewatchable. You notice the tiny details in the background of the precinct or the specific way Scully and Hitchcock react to food in the breakroom.
The Finale That Changed Everything
The season ends on a massive cliffhanger: "The Slaughterhouse." Jake and Rosa are framed for bank robbery by their idol, Lt. Melanie Hawkins (played by Gina Gershon). Unlike other seasons where things get wrapped up in a neat bow, this one ends with our heroes actually being found guilty.
Watching Jake and Rosa get led away in handcuffs was a genuine gut-punch. It shifted the stakes from "will they catch the bad guy?" to "how will they survive a broken system?" It was a dark turn for a show that usually ends on a high note, and it set the stage for a very different Season 5.

What You Should Do Next
If you’re looking to revisit Brooklyn Nine Nine Season Four, don't just binge it in the background while you're on your phone. You’ll miss the best parts.
- Watch for the Holt-isms: Andre Braugher’s delivery of the word "Puntual" or his excitement over a beige folder is a masterclass in acting.
- Pay attention to the cold opens: Season 4 has some of the best, including the "Full Bullpen" slide and the "I Want It That Way" lineup (wait, that’s Season 5, but the energy starts here).
- Re-watch "Moo Moo" with a friend: It’s a great conversation starter about how media handles sensitive topics.
- Track the Jake and Amy relationship: This is the season where they really settle into being a healthy, supportive couple, which is rare for TV.
The brilliance of this season isn't just in the big moments. It's in the small ones. It's in the way the characters love each other despite their flaws. It’s a reminder that even in a world that feels like it’s falling apart—whether you’re in witness protection or facing a prison sentence—having a squad behind you makes all the difference.
