Leon was so angry, so passionately angry that he couldn't speak, or think; his body shook with the force of his emotions. He balled his hands up into fists at his sides, his nails digging into his skin through his gloves. There were a few long, silent moments where he tried to gather himself, tried to calm himself down, but the more he tried the angrier he became. Those terrible blue eyes bore holes into him so demandingly, unwavering in their accusation that Leon wanted to rip them out of the owner's face. That's when he exploded with blind rage, his body seeming to move on its own. His hands grabbed around for the nearest object which happened to be a crystal vase, and hurled it across the room with such force that the crystal seemed to shriek past William's head. It exploded against a wall shattering into a million little pieces, and sprayed across the floor; a sharp piece cut deep across William's left cheek. Leon didn't stop there, and blindly threw a chair, toppled a desk, broke several panes of the balcony window, shattered the full-body mirror, and finally grabbed William around the neck and slammed him with bone-shattering force into the nearest wall.
William seemed genuinely surprised at the fingers around his neck, but had expected to make Leon angry with his comment, just not this angry. For the first time in a very long time, Leon inspired fear in him. This was not the man he fell in love with, rather the shell of him, a broken shell one that had been twisted by time and his surroundings and beaten into an emotional train wreck. The man he loved, the one he'd forsake his own wife for was not the same. Those beautiful eyes had grown so cold, and his hands did not waver, swiftly bringing death to his father's enemies. He really could not understand his lover anymore, and as hard as he tried, Leon slipped through his fingers time and time again.
The distance between them grew every year. He needed an answer, and so even though he was in no position to, he prodded again, "You were proud once, and now? What are you n--" Leon quickly cut him off unable to take the vile words.
An almost primal growl erupted from Leon's throat, and now both hands were wrapped tightly around William's throat, squeezing hard as those unwavering blue eyes starred at him. His breathing was so ragged it was deafening in his ears and only seemed to grow louder and louder until finally he couldn't take it anymore and yelled loudly at William, "STOP!" He starred down at the floor trying to check himself and his anger, slowly loosening his grip on William's throat. "Stop...Just stop. Stop looking at me like that!" Leon let out a very exasperated noise, tripping over his words, his eyes welling up with tears of frustration. The problem was, he didn't know what was wrong with him, and he had just
closed himself off. He trusted things would be better that way, he'd grown very fond of William
and yet he could not stand to see that man with a wife and children, and him
all the way on the side. This was not a relationship he wanted, and his life was already hard enough.
William swallowed hard, finally looking away from Leon, he couldn't stand to see him like this; it was truly one of his lowest moments. Easily he pushed Leon's hands off of his neck, rubbing the painful, already bruising marks. He felt so terrible, so wrong and dirty, but couldn't take back those words; he couldn't turn back the clock. Now, he was quite concerned with Leon's next response and remained silent, unmoving, and listened with a painful expression as Leon gasped trying desperately to stop the sobs that wracked his frame.
They had been together almost ten years and Leon had grown much in that time, physically and mentally. Leon had become very efficient at his magic, very graceful, and deadly in his fencing and was quite absorbed in his studies. However
lately, he'd push William away whenever he could, rather, as often as he could. Leon was not the same since his "missions" had become more violent, more personal, especially the constant abuse from his father; he held Leon's leash so tight, and twisted it every time he'd refuse. Leon had given up his freedom long ago; truly he understood that better than anyone else. forcing him into terrible acts, twisting his arm at any little protest saying he could easily and would willingly kill his mother; she was the only family he had left. At times Leon was so consumed with his goals that he did not return for weeks, at the most three months and refused help from others even when ordered to take it. Their relationship grew tenser each time they actually got to see each other, and Leon's mood swings left William confused, sometimes terribly angry. To see Leon at his lowest point, to see his lover was suffering such deep emotional and spiritual trauma, it left him with a very sick, empty feeling. He blamed himself for not trying hard enough, but what could he do? This was their life.
Leon's clung tightly to William's uniform, the blue fabric bunching and wrinkling in his grasp. He pushed William hard back against the wall when the man moved to embrace him, wanting desperately to take that affection, but feared he had already shown William so much of his weakness; he couldn't bring himself to take it. William was right, what the hell did happen to him? How did he get like this? When did it get so bad? His stupid pride always got in his way, but most of all he dared not share his burden with others; especially his mother. She could never know how much he was suffering for her, he loved her far too much to ever make her sad. He followed his orders, he buried his feelings, and somewhere along the way he ran out of room for all of them.
Even though he hated the idea of breaking William's marriage up, he couldn't bring himself to let go of him. William pushed him so hard, kept him with-in arm's reach even when he didn't want it, and proclaimed his love often and annoyingly...but...what would he do without it? The parameters on their relationship only made him more frustrated and upset. 'I hate you.' He let go of William backing up and covering his face with his hands. 'I hate you so much that it hurts. I hate that I love you so much.' Leon inhaled very sharply regaining very little control over himself, and he squat there pressing his palms hard against his eyes until he saw stars. He bit into his lower lip hard enough to draw blood, trying his best to contain himself. The sound of William's boots against the floor, glass cracking under his heels surprised him, but the gentle hands on his shoulders surprised him even more, enough that he flinched and pulled away.
Leon immediately looked up at William his expression so utterly confused, and that's when it clicked: as much as he hated this man he really needed him too. Without thinking he stood up, wrapped his arms around William's neck and shoved him back against the wall, this time desperately and greedily kissing him.
William and Leon's relationship lasted thirteen years, and Leon finally broke it off, unofficially by leaving his home; he didn't return for thirty years. So, I'm estimating something like this happened their tenth maybe eleventh year, a precursor to the end if not horrible death of their relationship. When Leon eventually did return to his home, he did not want to start a relationship back up with William no matter how in love William was with him, and it hurt him too to make that decision, but he couldn't start them back up again. William had two children, a wonderful wife and Leon refused to be the "other woman" in William's life. So, he focused more on his own goals, like killing his father, half-brother and toppling his father's legacy. His lust for revenge was stronger than his lust for William.
