- Chow Mo Wan: Love is all a matter of timing. It's no good meeting the right person too soon or too late. If I'd lived in another time or place... my story might have had a very different ending.
- Tak: Do you know what people did in the old days when they had secrets they didn't want to share? They'd climb a moutain, find a tree, carve a hole in it, whisper the secret into the hole and cover it up with mud. That way, nobody else would ever learn the secret...
- Tak: I once fell in love with someone. I couldn't stop wondering if she loved me back. I found an android which looked just like her. I hoped she would give me the answer.
- Tak: Every passenger going to 2046 has the same intention: they want to recapture lost memories. Because nothing ever changes in 2046. Nobody really knows if that's true because nobody has ever come back. Except me.
- Tak: Let's see each other again. Then, if you think we shouldn't be together, tell me so frankly... That day, six years ago, a rainbow appeared in my heart. It's still there, like a flame burning inside me. But what are your real feelings for me? Are they like a rainbow after the rain? Or did that rainbow fade away long ago?
- Chow Mo Wan: When you don't take "no" for an answer, there is still a chance you'll get what you want.
- Chow Mo Wan: He didn't turn back. It's as if he boarded a very long train headed for a drowsy future through the unfathomable night.
- Bai Ling: I don't get it. Where does all that fun get you? If you find the right person, why waste time on the others?
- Chow Mo Wan: If I find the right person? A man like me has nothing much except free time. That's why I need company.
- Bai Ling: So people are just time fillers to you?
- Chow Mo Wan: I wouldn't say that. Other people can borrow my time too.
- Bai Ling: And tonight? Are you borrowing me, or am I borrowing you?
- Chow Mo Wan: No difference. Maybe I borrowed you earlier... and now you're borrowing me.
- Bai Ling: Ridiculous.
- Chow Mo Wan: I slowly began to doubt myself. Maybe the reason she didn't answer was not that her reactions were delayed but simply that she didn't love me. So at last, I got it. It's entirely beyond my control. The only thing left for me... was to give up.
- Chow Mo Wan: Do you remember you asked me if there was anything I wouldn't lend? I've given it a lot of thought and now I know there is one thing I'll never lend to anyone.
- Tak: I once fell in love with someone. After a while she was gone. I couldn't stop wondering if she loved me or not. I went to 2046 hoping to find her there. But I never found her.
- Tak: I want to know how you feel. I'm scared to hear your answer but, I need to know. Do you like me? Or not. Leave with me.
- Mr. Wang: Our cabin attendants are superbly designed... But there's only one problem: when they've served on so many long journeys, fatigue begins to set in. For example, they might want to laugh, but the smile would be slow to come. They might want to cry, but the tear wouldn't well up till the next day...
