Jake: Ugh, this place smells like-
Rosa: Regret? Failure?
Jake: Ketchup.

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.

Jake: Well, listen, we need your help.
Adrian Pimento: Great, who are we killing? I won't do kids. That's a rule. But that rule is negotiable if the kid's a dick.
Rosa: No, babe, we don't want you to kill anyone.
Adrian Pimento:What? Really?
Rosa: No.

Charles: Sarge, you think Gina will be okay?
Sergeant Jeffords: She says the doctor's can't be sure, but they're optimistic. Apparently, she has something called Ansel-Elgort Syndrome.
Charles: Oh, poor Gina.
Amy: Oh, my God.
Hitchcock: Oh, you fools. That's not a disease. Ansel Elgort's an actor. Did none of you see "The Fault in Our Stars"?
Sergeant Jeffords: No. Why did you?
Hitchcock: Teenage romance, dying chick, oxygen mask. Checks all my boxes.

Adrian Pimento: Okay, here are the ground rules: You can punch me, kick me, pull my hair, I am a-ok being stabbed, biting and scratching are on the table, you can use fire.
Jake: These are the ground rules? Is there anything off limits?
Adrian Pimento: Damn, man. You got something really sick you wanna do, huh? Oh, you little pervert. All right, I like it. Don't tell me. Surprise me. Ooh, this is gonna be fun.
