Analysis of the ending
I got the feeling that whenever Christine was with the guard she seemed to perk up and later once she was 'cured' she seemed to walk 'faster' and generally looked healthier. Remember when they walked up the mountain and her room mate (the older lady) couldn't keep up with them?
It's as if the possibility of 'love' cured her, ie, the psychological effect of 'hope' seemed to be her own personal 'miracle', and she did not have a religious 'awakening'.
Later during the farewell party, remember it is she who goes up to the Guard and he then asks her to dance (obligingly imo). I beleive that as she danced she realised that there was no future for them, that he wasn't going to take things further, he wasn't even talking to her, like trying to get her contact details or anything, and that's why she fell, as if her 'hope' had faded and hence her psychological crippling started to take hold of her again. Then when they finish dancing they are just standing together and he STILL doesn't say nothing to her and then tells her he will come back soon but you see her there waiting and waiting but you don't see him comeback, suggesting that he possibly did a 'runner' and 'disappeared'.....hence right at the end, she sits down in her wheelchair, which to me insinuates that the disease will take hold of her again.
Anyone agree or see the ending in a totally different light?
