- Bob Keaton: What is this? Who are you?
- Horatio Caine: Bob, we located methamphetamine in a car registered to you, and now you will be detained for questioning.
- Bob Keaton: [to Susie] Are you kidding me? Susie, what are you, an idiot for bringing them here? What'd you do, drive up on a curb again, you stupid bitch? I ought to crack your head.
- Horatio Caine: Hey. Hey, Bob. The next time you feel like taking a swing at somebody, you start with me. You understand me?

- Horatio Caine: Some... some sooner than others, Bob.
