Rosa: They said Seamus' girlfriend Nikki works in a hair salon in Bay Ridge.
Charles: Nice, classic mistress job.
Hitchcock: Hey, my girlfriend's a hairdresser!
Charles: And you cheated on your ex-wife with her.
Hitchcock: Checkmate. Well played.

Amy: Hey, I think I found something interesting. I was double-checking last month's surveillance photos, and I noticed this. Hawkins has two different phones: her normal cell, and then this one that only has one app on the home screen Snapchat.
Hitchcock: Oh, she's up to something. Snapchat messages disappear. You can send anything to anybody, and after they see it, it's like I never sent it.
Captain Holt: Nobody ask Hitchcock why he knows that.

Sergeant Jeffords: Hitchcock called himself Scully by accident.
Hitchcock: I did, but it brought me and Scully closer together.

Amy: Hitchcock, why do you have your shirt off?
Hitchcock: Can't spill food on your shirt if you're not wearing one.

Captain Holt: Hello, Kevin. It's me, Raymond Holt. We need to get you to safety. Your life is in danger.

Captain Holt: I brought you your box of DVDs.
Jake: Oh, thank you. Oh! Forgot about this one. We never watched "Captain Corelli's Mandolin".
Kevin: What the hell did you just say?
Jake: "Captain Corelli's Mandolin"?
Kevin: Say that to my face.
Jake: "Captain Corelli's Mandolin"?
Kevin: There was a movie about a mandolin, and you kept it from me for two months?
Jake: Well I didn't think it was any good. It's just some period piece.
Kevin: What?
Jake: Set in Greece.
Kevin: Oh, my God.
Jake: Based on some dumb book. *Kevin knocks the DVD out of Jake's hands* Aah!
Kevin: Terribly sorry. It has been a very trying time.

Jake: But going out into public is a huge risk, so maybe let's go over some self-defense techniques. *Kevin punches Jake in the throat* [gasps] [chokes] Usually, you warn somebody before you do that.
Kevin: Raymond told me that the element of surprise was crucial.
Jake: Cool. [coughs] So he's a great teacher. But I will say this. If you're going to do a throat punch, it is key that you say something cool afterwards like, "choke on that".
Kevin: Right, but they're not choking. They're experiencing airway trauma. Ooh, how about, "Better get some corticosteroids to treat that laryngeal fracture".
Jake: Okay, yeah, that's very informative and quite polite. [ahem] But maybe add a "dirtbag" on the end?
Kevin: But a dirtbag is a useful part of a vacuum. I don't see how it's an insult.
Jake: All right, you know, puncher's choice.
