- Peter Caine: What more can you teach him?
- Kwai Chang Caine: Why.
- Peter Caine: All right. Forget I asked.
- Kwai Chang Caine: No you misunderstand. In his haste to master the "how" the technique, he has forgotten/brushed past the "why", the meaning.
- Kwai Chang Caine: You have a lot to learn, my son. But you do have a good right cross.
- Marie: [handcuffed, to Peter] You ever thought about fighting?
- Peter Caine: Marie, you're under arrest.
- Marie: Yeah, and I'll be out of jail before you finish the report.
- Peter Caine: Not this time.
- Peter Caine: Look, if any of these scumbags touches you, or gets near your family, I'll have the whole Metro division on them.
- [Assuring Jake against the street fighters]
- Laura: Oh no. Daddy?
- [Tries to call him again]
- Laura: Oh my god. Daddy?
- Kwai Chang Caine: He is... dead.
- Laura: Oh dear god no.
- [to Marie]
- Laura: You killed him!
- Marie: Me? I never touched him. I'm as sick about this as you are. I lost a yard and a half on him.
- Laura: He never would have fought if it wasn't for the money you offered.
- Marie: What he did was his choice.
- [Kwai turns to Marie]
- Marie: What? What's that look? You got something to say? Look, this was just a little neighborhood punch-up. Couple of guys getting it on. Who knew the bum couldn't take a punch?
- Laura: Dont you say that! He wasn't a bum!
- [Punches and slaps Marie]
- Kwai Chang Caine: [Stops Marie from punching Laura] You do not want to do that.
- Marie: What have we got? A tough guy? Relax, China man.
- Kwai Chang Caine: There is a word for people on other's pain and misery.
- Marie: Entrepreneur?
- Kwai Chang Caine: Coward.
- Marie: It's all just words, China man. Until the whistle blows, it's all just words.
- [as they enter the street fighting arena, the doorman stops Donny and starts patting him down]
- Donny Double D: Ah, the clarity of this gesture is not lost in its lack of eloquence.
- Peter Caine: What?
- Donny Double D: Just give the man your gun.
- Peter Caine: Oh no, I promised my mother I'd never give my gun to strangers.
- Donny Double D: Petey, Petey, a breach of weapons-related etiquette could have the most alarming consequences. Besides, you ain't gettin' in 'til you lose the heat!
- Peter Caine: [after Kwai Chang has started teaching a new student] What more can you teach him?
- Kwai Chang Caine: Why.
- Peter Caine: All right. Forget I asked.
- Kwai Chang Caine: No. You misunderstand. In his rush to master the "how", the technique. He has brushed past, or forgotten the "why," the meaning.
