The Boss: That's all there is to it.
Slevin: Is that all there is to it?
Mr. Goodkat: Yup... That's all there is to it.
Lindsey: Thanks for the sugar, sugar.
Lindsey: I was just thinking that if you're still alive when I get back from work tonight... maybe, I don't know, we could go out to dinner or something?
Lindsey: We are dealing with a bona fide case of mistaken identity here.
Slevin: Yeah.
Lindsey: Things like that aren't supposed to be real. It's like amnesia.
Lindsey: Not withstanding, here you are and Nick's nowhere to be found, so... I'd say you're fucked.
Slevin: Fucked.
Lindsey: Shouldn't you be a little more worried about all this?
Slevin: I have ataraxia.
Lindsey: Ataraxia?
Slevin: It's a condition characterized by freedom from worry or any other preoccupation, really.
Slevin: Ok, I'm under the impression that you're under the impression that I owe you 96,000 dollars.
The Boss: No, you owe Slim Hopkins 96,000 dollars. You owe Slim, Slim owes me... You owe me.
Slevin: I have ataraxia.
Lindsey: Ataraxia?
Slevin: It's a condition characterized by freedom from worry or any other pre-occupation really.
Answer: When Slevin first tells Lindsey about his time in New York, he told her he was mugged and got his nose broken. We later find out this isn't true. To make his story seem valid, however, Goodcat breaks his nose.
