- Cola's mother: [to Cola aged 14, after Wong Jiang is accused of killing 7-up] You remember this man.
- Chan Lok-Yin: [narrating] This is the man that killed my father. Wong Jiang, the Chief Inspector of the Regional Crime Section. I'll never forget his face.
- Chan Lok-Yin: [narrating] Maybe Rebel Without a Cause had a good box office record. So many boys imitated James Dean. They played tyrant everywhere.
- Chan Lok-Yin: [narrating] In 2001, I had graduated. I had achieved my goal to got into the police force. Mom remarried again. Now, my name is Li Tak Yan. Nobody remembers that I'm the son of 7 UP. It's the same in the police force, so I treasure my naked name, Cola, more. My colleagues also call me Cola. This name reminds me that I am the son of 7 UP. And the hatred for the one who killed my dad never goes away. Wong Jiang, S.P. of the Regional Crime Section.
- [last lines]
- S.P. Wong Jiang: I killed your dad. Why don't you take revenge?
- Chan Lok-Yin: My dad wasn't a good cop... But I am.
- Chan Lok-Yin: [after shooting Wai instead of Wong Jiang] S.P. Wong taught me to keep a bullet at hand.
- Wai: Why?
- Chan Lok-Yin: It's simple. You're a thief. I'm a cop.
- Chan Lok-Yin: [narrating] This was the first time I saw Wong Jiang again. It's unbelievable to see him again like this. What kind of person is he? He dared to hold the grenade alone. He's not ordinary. Mom was right. He is such a refined evil. I must beware of him.
- S.P. Wong Jiang: Oh, you don't wanna hear it? If so, then Alan Tam doesn't wanna sing, and Lee Lai Shan doesn't wanna sail.
- Chan Lok-Yin: [narrating] I can't believe Wong leads such a simple life. It's a total contrast with the sly old fox I had in my mind. So, why did he kill my dad? No. It's just what he pretends to be.
- Wai: [persuading Cola to consider killing Wong Jiang] Haven't you thought of revenge? Haven't you thought of shooting him when he isn't noticed? Don't tell me you haven't. Matthew 7:15 in the Bible says, "Watch out for false prophets. They come to you in sheep's clothing, but inwardly, they are ferocious wolves." I believe God has arranged everything. Maybe, you don't get what I said just now, but I'm fair. Wong gave my dad one shot. I'll give him one shot back.
