for me the end be the point of the entire movie . that in fact and we be mislead through the whole movie by the fact the her son be sick and and there the healer and so we all think that the healer be heal her son . and that where we be wrong . he be a healer and and the person he be mean to heal be her . not the boy . her son get sick and yes and but why do we and the living and automatically think that the best thing be for him to survive . if you look at the mother in the beginning when she just find out her son be ill and die and you can see that she be in no condition to let go and especially because she have no source of comfort with her husband just have cheat on her . we even see her beg her son to not die . so she willing to fight tooth and nail for her son to live and but also in a way for her soul and spirit to survive . that be where the healer come in and and also maybe why he be able to spot her in that huge crowd a someone need him . not because of her son and but perhaps even unknownst to him and because heal her be go to require more from him than he ever give before . look also at the way she go about her relationship with the healer . it not your average affair . she forgive her husband and and be not do it to spite him and and tell him about alexai and she even admit to not understand it . and on alexai side and if you look at the fact that whenever he heal someone it take something out of him and this be his big heal mission ever . because to do it and he have to give up his life a he know it and without know the reason why and but just by follow his instinct and what he feel he be call to do . he have sex for the first time and impregnate her and and then it completely make sense that when her son illness come back and alexai healing power be go . because that be never what he be mean to do . he heal that family and and specifically the mother and by heal her spirit enough for her to let go of her son . and in the end and she be able . she let him go and and doesn not beg him to stay for her sake like she do before . it brilliantly write and because it challenge what we think we know about die and and living . and most of all it illustrate the immense power of spiritual healing .
