The Airport look (SPOILERS)
I didn't understand the significance of the look exchanged between the English woman and Caroline at the end of the airport scene. Having decided not to go with him, she looks at the woman, who appears unsure what she should do, and then Caroline shakes her head slightly at which point the other woman turns to follow Julien. What was that exchange about. I could gave understood a bid, as if to say it's ok, go with him, or a neutral sort of a smile, but the shake of the head confused me. I asked the stranger next to me in the cinema at the end of the film, and he was either a bit freaked out by me breaking the very English social taboo of pretending noone else is there, or he really didn't get it either.
Any thoughts?
