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?

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?
