The Bumper Cars Scene
During the bumper cars scene, Pierre's wife kisses him, and the camera shows us Francoise looking on. But Francoise could not have been there: it was Sunday, and her "father" had not come to pick her up. And if she really was supposed to be there, we would surely have seen more of her, during the brawl or while the group got into the car and pulled away. And we would have had some explanation for how she got there without her guardian taking her.
So at first I assumed this was just a POV thing--that Pierre imagined her seeing the kiss, out of his own guilt and panic. But later, in a conversation between them, she mentions the kiss. So either a) she really was there, which makes no sense at all, or b) the film is suggesting some kind of spiritual telepathy between the two. I like explanation b better. Does anyone have a more definitive interpretation?
