Okay, so I figured I would take a crack at the RoyAi themes. Beware...they might -will be totally rambly. And mostly focus on the characters' thoughts and such instead of actions and a proper...scene.
Theme oo1: Military Personnel
Her father had hated the military. It was, perhaps, a trait he had passed down to her as well. She held no respect for those men and women dressed in the blue uniforms, killing under the pretence that they were 'keeping their nation safe.'
The only reason the nation needed to be kept safe was because of the fact that it was ruled by the military.
Yet, as much as she hated the military and the soldiers who had lowered themselves to becoming its puppets, she could not bring herself to hate him.
Roy Mustang, having returned from a year away in order to prove that he was capable of learning his master -her father's brand of alchemy, had strode right in, wearing that familiar, yet foreign, blue uniform. Like the rest of the soldiers, he had brought death with him.
She still did not hate him, nor did she blame him for her father's death. It had been unfortunate timing (or maybe, she would later think, that was the price of the uniform).
At the funeral, he had managed to shake her –once her father's- views on the military. Or maybe she had just been moved by his dream, his determination and his passion for his country. Even if he had become a soldier, he was still him and she was certain that he would not fall as low as the others. His dreams had been reason she showed him her father's work.
His dreams had been the reason she had followed him into the military (the fact that she couldn't stand the thought of living alone in that house, tied down by her father's research may also have been a contributing factor). She wanted to be useful, to help people, too. She wanted the future that he had told her about.
It was later, with the feel of blood on her hands and the weight of innocents on her shoulders and the burden on her back, that she realised she had placed her hopes in a nightmare instead. And so had he.
She still could not hate him; even as the flames ravaged whole districts in a matter of seconds, destroying hundreds of lives with only a snap of gloved fingers, even as she tried to ignore the screams coming from inside one of the more intact buildings –an old hospital of sorts- as he helped with their sick experiments. Every time that array (an array which had been as carefully, slowly stitched into white gloves as it had onto her back) was used to take even more lives, she swore she could feel her own back burn with their pain.
A pain that she would later willingly bring upon herself so that there would be no more white gloves, no more 'flame alchemists'. So that no one else could ever use her father's work as a weapon.
She would never hate him. Even if she hated herself, even if she resented –only a little- her friends in the military, even if she felt a pang of remorse every time she saw Edward with his pocket watch. Roy had been impacted by the war far worse than she had. He was too empathetic, whereas she had learned long ago to bury her emotions, hiding them from public view in order look strong, hiding them from even herself.
She would remain that way, strong. For his dream, for that future, for him. She would remain a part of the military she hated, she would remain a soldier she loathed, just so he could protect him and, by doing that, protect her country.
She could live with what she had lowered herself to because they would help each other back up again.
This one: while I, myself am of the belief that Riza is not in the military purely for Roy, but for the future of their country (their dream), I think it would be nice to say that he's the reason she's there. Because it does need to seem a tad more like RoyAi.
Don't I have another story to be writing? Yes...yes I do...
