Quote from Rosa in the episode The Last Day (Part 2)
Rosa: So, my plan was simple. The best way to win is to sit back, watch everyone else, and then choose your moment. But to do that, I needed people to think I was gone.
Gina: It's a trick she learned from me. [lisping] During the fourth heist, universally considered the best heist.
Rosa: You were so eager to think I'd drop everything and chase after Adrian.
Amy: So you don't want to end up with Pimento?
Rosa: No, but you believed it because you all think for someone to be happy, their story has to end with marriage and kids.
Amy: I mean, I believed it because you told me and I trust you.
Rosa: Whatever, breeder.
Quote from the episode 9 Days
Rosa: I want to say a few words. When Jason died seven days ago, I didn't give a rat's ass.
Charles: This is your speech?
Rosa: 'Cause I didn't understand why people care so much about their dumb dogs till I got a dumb dog myself. I've only had Arlo for a day and a half, but if anything happened to him, I would kill everyone in this room and then myself.
Gina: Very violent eulogy, I like it.
Quote from the episode Jake and Sophia
Rosa: Hey, you should run. Going to meetings, writing stuff down. You love that nerd stuff.
Amy: Writing stuff down is nerdy? What do you do?
Rosa: I just forget stuff like a cool person.
Quote from the episode The Road Trip
Sergeant Jeffords: Wait, is that a smile I see?
Rosa: Possibly. My immune system is too weak to fight off my smile muscles.
Quote from Jake
[about a year later:]
Sergeant Jeffords: Now that that's been sorted, are there any questions?
Jake: Yes! I have a question! Captain Jeffords, are you ready for the Halloween Heist?
Sergeant Jeffords: What are you doing, Peralta? Last year was the final heist. We all agreed it was over.
Jake: Ah, Terry, you jolly simpleton. That was obviously a ruse. I mean, did you really think I was gonna let Hitchcock win the last heist? I mean, that would be crazy! Hitchcock? It would've been unforgiveable.
Hitchcock: That's true, it felt wrong.
Captain Holt: I know someone who's in. The old janitor, which is actually me! Deputy Commissioner Raymond Holt.
Amy: And he's not the only one. I'm in too.
Rosa: Me too.
Gina: As am I. Gina Linetti.
Jake: That's right, Terry, this is happening every year. We're in each other's lives forever, whether you like it or not. So, what do you say, Captain? Are we doing this?
Sergeant Jeffords: What I say is... Nine-Nine!
All: Nine-Nine!
Quote from Hitchcock
Hitchcock: I bet you're all wondering how I pulled it off.
Rosa: Not really, but I guess that's the tradition.
Hitchcock: The key to the whole plan was that I never really retired or moved to Brazil. I've been living in the Beaver Trap this whole time.
Jake: Okay, but what was the rest of the plan?
Scully: Oh, we had not come up with it. But then Bill came by and offered to sell me the tube for 40 bucks and I won.
Scully: Pretty good stuff.
Hitchcock: Now, crown me.
Jake: Ugh, this stinks. Okay, Michael Hitchcock, you are an amazing human/genius and the Grand Champion of the Nine-Nine. Why is your head so sweaty?
Hitchcock: Oh, because that's actually butt skin from a botched hair transplant so there are more pores.
Jake: I can't believe this is how it ends, with Hitchcock's sweaty butt head.
Scully: I told myself I wouldn't cry.
Quote from Charles
Jake: Charles, I just want to be there for Mac.
Charles: I get that, but this whole thing is just taking me by surprise. I don't know if I can come in to work and do this job without you.
Jake: Are you kidding me? I mean, maybe the you of nine years ago couldn't handle it, but you're not that person anymore. You used to live in your ex-wife's husband's basement and date 75-year-olds and now you've got your own house and Genevieve and Nikolaj.
Charles: Nikolaj.
Jake: Nikolaj.
Charles: Nikolaj.
Jake: Nikolaj.
Charles: Nikolaj.
Jake: Why don't you just call him Nick?
Charles: Nik.
Jake: All right, now you're ruining the moment.
Charles: Copy that.
