Jake: No matter what happens, you're not allowed to fall in love with me.
Amy: Won't be a problem. (The Bet)
Jake: The truth is our job isn't always great. I mean, sometimes it sucks. But, it sucks a little less when I get to do it with you. (Operation: Broken Feather)
Jake: What do you think Amy sees in Teddy?
Charles: So, you do like her.
Jake: I'm just curious. I mean, I guess he's okay-looking. And he's a good cop. They're both kind of dorky about police stuff. Also, he set the course record, but that's nothing. I broke it, like, 20 minutes later.
Charles: You want to know why she went out with him and not you?
Charles: Because he actually asked her out. (Tactical Village)
Jake: I don't know what's gonna happen on this assignment, and if something bad goes down, I think I'd be pissed at myself if I didn't say this. I kinda wish something could happen between us, romantic-styles. (Charges and Specs)
Jake: The thing I said to you before I went undercover, about how I wish something could happen between us romantically, that wasn't nothing. That was real.
Amy: What are you saying?
Jake: I know that you're with Teddy. I'm not trying to change that. And I get there's stuff I can't control. But this morning I told you that I didn't mean any of it, and that was a lie. I just don't want to hold anything back.
Amy: Well, thank you for saying that. (Undercover)
Teddy: And if you ask me, I think it's because Amy liked you back.
Jake: Did you?
Amy: Maybe. Yes. A little. (The Road Trip)
Jake: Don't get me wrong, I'm pysched that you liked me. And I plan to tease you with it every chance I get.
Jake: I referred to myself as "El Baboso" to several beautiful Latina ladies.
Charles: Ah, that's your type, isn't it Jakey? Sophia and Santi-
Jake: [stammers loudly] (The Wednesday Incident)
Rosa: Look, if you want to give her a real choice, you've got to let her know that you are an option. (Det. Dave Majors)

Amy: Thank you for doing this. I love you.
Jake: Noice, smort... I love you too. (The Cruise)
Amy: And its midnight, so I guess I'm an amazing human/genius.
Jake: Yeah. Although...You might wanna read the inscription on that there belt.
Amy: Why? Oh, no, what does it say? "Amy Santiago, will you marry me?"

Jake: "I'm so confused, I don't know what's happening right now," title of your sex tape.
Amy: "Oh my god. I'm shaking, I'm definitely gonna cry." Title of your sex tape... Wait, is this really happening? Is this part of the heist? If this is part of the heist, I will dump you so hard.
Jake: No, please. Ames, look, it's really happening, okay? It's not part of the heist. I promise, this is real.
Amy: It is?
