I would add re: Roy/Riza that I feel there is far too much history between them for them to possibly function as lovers. I'm aware that this is one of the arguments used in favor of shipping them, but that history is pretty damn steeped in guilt. The fact that Roy misused (even if it *was* under orders) the knowledge that she entrusted to him, thereby becoming the very thing she wanted to avoid-- that's got to be a pretty major obstacle to romance. And how could Roy ever touch her without remembering the smell of her flesh as he burnt her back?

Maybe I'm extrapolating a bit much here, but while I totally buy into the two of them being united in their ideals, I think the possibility of romance is starting to strain plausibility.

Just my two cens. ;)
