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?

Sam:
What thousands must die, so that Caesar may become the great.

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 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?

Mary:
I can't finish the novel, I don't know whether he's good or bad.

Lau Kin Ming:
Do all undercover cops like rooftops?

Chan Wing Yan:
Unlike you, I'm not afraid of light.
