nice ideas, i hadn't realy thouhgt about that, i'd got a feeling it might be squall but i cant realy see him as a messenger.....but if i read into it more (too much) i could go as far as to say that as messenger in greek is angellos-angel (thanks Rand Al'Thor) i could say that squall is an angel because he rescues rinoa, protects her etc. but hey thats just reading too much into it!

on the R=U theory has any one contacted square to ask about it?
