When Kate (Meg Ryan) sees her finacée Charlie in the hotel with his girlfriend:
Kate: Happy, smile. Sad, frown. Use the corresponding face with the corresponding emotion. But no. You want this mysterious…
Luc: Non. No no no. It is not me who wants it. I don’t want it.
Kate: Well what do you want?
Luc: I want you… I want you…
Kate: You want me…
Luc: I want you… to… make Charlie suffer. To make him feel like even though you are right there in front of him, he can’t have you.
[he realizes then that he is talking about himself]
When Kate is about to fly home and Luc (Kevin Kline) stops her (favorite scene)
Kate: [hopefully] Yes?
Luc: You are not afraid to fly any more? You are thinking of your little stone cottage?
Kate: It’s on a hillside next to a beautiful vineyard. But that’s not really what I’m thinking about.
Luc: What are you thinking about?
Luc: And I am thinking, you should not be flying anywhere.
Kate: I shouldn’t?
Luc: No, in fact, I am sure of it. I am thinking, I want you.
Kate: You want me?
Luc: That’s all. I want you.
