Jake: There you are, my cheating my wife! Give me the tube.
Amy: I don't have it. The baby's empty. You lied to me!
Jake: I'm not the liar, you're the liar. I put a tracker in the tube so I know you've hidden it somewhere in this... nope, you were telling the truth, it's on the move. Someone else has it.

Rosa: Come on, Peralta! Holt said to use the whole team. We all want this solved.
Jake: I appreciate the offer, but I work best alone. Except when it comes to sex. Actually, sometimes including sex.

Jake: I wasn't hurt that badly. The doctor said all my bleeding was internal. That's where the blood's supposed to be.

Jake: I guess that's your new best friend now, Santiago. Emphasis on "Iago," backstabber.
Amy: I'm surprised you've read Othello.
Jake: What the hell's Othello? I'm calling you the parrot from Aladdin.

[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!

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.

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.
