What do you get a competitive, comedic cop couple for their wedding?

Oh, just a bomb threat.

And a determined ex-lover.

Also, a threat to a veil.

(Veiled threat?)

Perhaps a canine ring bearer.

And definitely a Nakatomi Plaza-shaped cake.

(Well get to that bomb threat in a minute.)

How has this off-beat, on-the-beat romance transformed into one of prime times most endearing and entertaining relationships?

Theyre both super nerdy, agro into their jobs, and theyre both slightly savant brilliant at their jobs.

And then, all of the surface stuff is very different, which makes for good comedy.

It excuses everything else and is the thing that makes you feel at home.

They didnt have secrets, but it also meant that certain kinds of stories were out of bounds.

Like, them breaking up for no good reason.

I remember refreshing my email constantly the day that the script was coming out, shares Fumero.

I couldnt wait to read what they wrote.

And once I started to read it, it was just page after page of being like, Yes…

Yes… Oh my God,yes!

Oh, thats great!

Its soBrooklyn Nine-Ninethat we cant just have a few mishaps, notes Fumero.

It cant be a little thing, it has to literally blow up in a big way.

But dont worry, there are little things aplenty.

I really enjoy the kind of pleasant sociopath that hes turned into, says Samberg.

Adds Fumero: Of all people, he was the worst person to show up on that day.

Teddy showing up is actually a little worse than the bomb threat.

Rosa is rattled by someone unexpected, too, though in a more romantic way.

Cue: a rideshare driver named Alicia.

Turns out Rodriguezs name has been on theBrooklynguest-list wish list for a long time.

Shes a dear friend of ours.

And so to have her there for the finale was this awesome full circle.

And it seems like Rodriguez might play a role on the show beyond the finale.

Its very intriguing, adds Fumero.

I feel like it feels like a set-up, like theres more story to tell there.

Like, for alongtime.

The jokes and the heart kind of sneak up on you, warns Fumero.

For me, watching it the first time, it felt very much like a reward.

It was a thrill and a privilege to see it.

Heres hoping that fans feel the same way on finale night.
