Martyrs
Rewatch
(And a chance to yap about my theories about the ending to…nobody)
I think, Anna’s feelings and love towards Lucie are romantic and that’s why she is so willing to do so much for her and get her out of any situation even though, at that point in the film, she didn’t really believe or at least she had doubts that those parents were the people that tortured Lucie, but Lucie just sees her as her best friend and maybe even less than that. (A lot of people I’ve talked to about this film just thought they were a couple and the dialogue with Anna’s mom on the phone supports that theory so idk)
As far as the ending is concerned, for me it’s clear that Anna did see something but in my opinion there are three explanations and only two of them are actually plausible.
1. The very simplistic and not likely at all explanation that WHAT Anna saw made Mademoiselle kill herself. Either it was something really good and she couldn’t wait. Or it was something bad or nothing at all and she felt like her life’s “work” was for nothing.
2. The very plausible explanation that Mademoiselle realized something she didn’t expect. That now that she knows the truth of what the afterlife is, she has no reason to keep living anymore because that was her only goal.
3. The very plausible explanation that that was her plan all along. She always planned to find out the truth about the afterlife and then kill herself without sharing it with her “followers”/cult members. She had lied to them that she’d share it, of course, to get them to help her but she never planned to share what she would find out. That would actually make sense since she is portrayed as a very selfish, narcissistic, emotionless person with zero empathy who tortures people (gets others to torture them) and uses them to get what she wants.
And the fact that in the end she says to Etienne(who must be her ‘right hand’ or something) “Can you imagine what there is after death?”, “Keep doubting” can be interpreted as her “teasing” him knowing she’ll kill herself in literally a second and he’ll be left with no answers. And that makes sense because apart from an emotionless narcissist, she’s probably also some sort of sadist. I think this explanation is by far the likeliest.
