Rosa: I've only said I love you to three people. My mom, my dad and my dying grandpa. And one of those I regret.
Charles: Which one?
Rosa: Grandpa. He beat cancer so now I look like an idiot.

Sergeant Jeffords: The Captain's at a new level of anger, constant smiling.
Amy: It's horrible.
Rosa: All smiling is horrible. This is worse.

Amy: No, Rosa, we are doing something important here. We are women, standing up and supporting each other and becoming-
(Rosa closes the trunk with Amy inside)
Rosa: New fear: listening to Amy inspire us.
Gina: Be back in a half hour, Ames.

Rosa: [over radio] Peralta, you there?
Jake: Yeah, what's up?
Rosa: You gotta get back here right now. Amy's water broke.
Jake: What?
Charles: What?
Jake: When?
Charles: When?
Jake: Did she lose her mucus plug?
Charles: Did she lose her mucus plug?
Rosa: I can't believe you're making me say this, but she thinks she lost her mucus plug yesterday, but mistook it for normal discharge.
Jake: How thick was it? Was it clear or milky?
Charles: Was it bloody? Was it "the bloody show?"
Rosa: Jake, I think it's very cool that you've learned this, very progressive. Charles, I think you know you crossed a line. Just get back here, now!

Rosa: Tell me who has me for Secret Santa.
Hitchcock: No, that takes all the fun out of it.
*Rosa stares*
It's Scully. He got you a scarf. I'll make him return it.
Rosa: Yes, you will.

Gina: I can't believe this is one of the last things I'm ever gonna see.
Rosa: Actually, with Anthrax the last things you'll see will be doctor, blood, doctor, pus, scab, nothing.

Captain Holt: Diaz, are we still on for the polar bear swim tonight?
Rosa: It's either that or go carolling with my family, so yeah. I'd rather walk into the freezing ocean.

Rosa: Right, that's the guy you said the lame stuff about. Like he's a good listener.
Amy: Sorry, what do you look for in a guy?
Rosa: I don't know, real stuff. Like the shape of his ass.

Jake: Sorry I'm late. I had to go back to the deli and return my Everything Bagel. In what world does everything not include beef jerky?
Rosa: All of them.

Rosa: Anyone over the age of six celebrating a birthday should go to hell.

Rosa: Blink twice if you'd like me to mercy kill you.

Bob Annderson: So, Raymond, what evidence do you have that there's a dirty agent in the FBI? Let's see the file.
Captain Holt: We don't have a file.
Bob Annderson: You're working file-less?
Rosa: We saw the guy commit a felony. He tried to have a cop killed. Crazy hot cop.
Jake: Well, he's a specific type.

Amy: All right, that's enough. Can we all get back to police work and stop talking about wedding dresses?
Rosa: No. We're gonna talk about them, because while wearing a wedding dress, you leapt over a couch, sprinted down an alley, and jumped off a car to subdue the crap out of a perp like you were Wonder Woman. It was pretty cool, wasn't it? Amy, you are an amazing cop and a great leader, and you have proven that a billion times over. You can't let other people's opinions get in the way of what you want, especially because other people suck.

Amy: Whoa, Rosa! What happened?
Rosa: I touched poison oak. The doctor says I have to keep my hands bandaged for a week so I don't scratch them.
Amy: How did it happen?
Rosa: I was on a nature hike and I went off-trail to pick a pretty little flower.
Amy, Hitchcock & Scully: Aw.
Rosa: Shut up.

Rosa: I'm already seeing somebody, Boyle.
Charles: Oh, and just like that, things got interesting.
Rosa: And just like that, I left.
