Mélanie's awareness (spoiler)
I thought it was made fairly clear throughout the film that Ariane was developing more-than-platonic feelings for Mélanie. However, do you think that Mélanie saw Ariane's weakness and her apparent lack of true passion for her husband, as well as her new found closeness with Mélanie, and used this to her own advantage? Or do you think that Ariane's feelings developed without Mélanie's encouragement? I thought that Mélanie was definitely trying to manipulate Ariane and make her fall deeper in love with her when she gave her that lingering kiss at the concert. Do you think that Mélanie felt anything, anything at all, for Ariane, or was it all just a show to ensure that Ariane would lose everything by the end of the film?
This will all make sense in the end.
