- Lau Kin Ming: I have no choice before, but now I want to turn over a new leaf.
- Chan Wing Yan: Good. Try telling that to the judge; see what he has to say.
- Lau Kin Ming: You want me dead?
- Chan Wing Yan: Sorry, I'm a cop
- Lau Kin Ming: Who knows that?
- Lau Kin Ming: Do all undercover cops like rooftops?
- Chan Wing Yan: Unlike you, I'm not afraid of light.
- Keung: Remember this, if you see someone doing something but at the same time watching you... then he is a cop.
- Chan Wing Yan: Should I salute you?
- Lau Kin Ming: No, don't. How long have you been an undercover?
- Chan Wing Yan: I've followed Sam for 3 years; I had several other bosses before. All together, it's been 10 years
- Lau Kin Ming: 10 years? I should salute you, instead.
- Chan Wing Yan: I just want an identity. I want to be a normal man.
- Lau Kin Ming: Getting tired?
- Chan Wing Yan: You've never been a mole. You won't understand. Too bad I still can't find the stooge. I'll take him down if I've found him.
- Lau Kin Ming: Don't worry. Let me give you back your identity, I'll open your file, but I don't have the password.
- Chan Wing Yan: What's the Morse Code for undercover?
