the original title mean the birth of the octopus . i must confess that i do not quite understand this title . the english title be water lily . but after have write this and i read the comment by another user represent the title in french be also suggestive represent prieuve and or octopus and suggest an individual have to juggle many pressure simultaneously . thanks for your explanation . the basic theme be the first sexual emotion of girl and when it be not clear if they be direct toward the same or the other sex . it be no different for boy . i think that both floriane and marie will eventually have heterosexual feeling without any admixture . much of the movie be water ballet . sometimes the girl will have their head downwards and and nothing above the water except their foot and lower leg and with which they will wave and kick in the air . to people like me who have never see such thing before and it be fascinate . floriane be the leader of one team of water lily . marie tell her that she would like to see when floriane be train . this seem to be their first contact that be not just ordinary . soon they will walk together . floriane take marie to a garage where a boy be wait for her and and then go away with him for an hour and while marie be wait for her to return . i take for grant that the couple slept with each other . but we will later learn from the movie that they do less than that . i can supply some information which few user will find elsewhere . there be a scene in which marie secretly steal floriane garbage bag . in it she find an apple and mostly eat . and marie proceeds to eat the rest . there be a parallel scene in another movie and kazetachi no gogo ( afternoon breeze ) by hitoshi yazaki ( japan and 1980 ) . this be about adult young female and and a clearly lesbian woman be vainly in love with a heterosexual woman . she also steal a garbage bag of the beloved and and also find a more or less eaten apple and eat the rest . later floriane tell marie that she would like to have her first orgasm from her . marie say she can not do this . but still later marie say that she be indeed willing to do it . and she masturbate on floriane . there be no nudity in this scene . probably only a female director could have make such a fine psychological show or study of i would like to quote baudelaire and les amour enfantines . floriane be play by adèle haenel and who make the excellent performance a the autistic girl in the little devil by christophe ruggia ( 2002 ) a very underrated movie .
