Chapter 90:
The trial itself held very little interest for Harry. Both he and Sirius knew all the facts that would be revealed - Harry from his last life and Sirius from being there and hearing Harry's tale. The only point of interest was Dumbledore, who stood up and asked for leniency, stating fear was a great motivator. At that point, Harry actually had to bite his tongue to stop the curse from coming out. He had never actually performed the killing curse, but at that moment he knew with certainty he would have gotten it on his first try. He sat staring with his Avada Kedavra green eyes, glaring into the back of the old man who had literally ruined his first life.
Sirius, who was doing the same, was soon drawn away from his anger when he felt Harry's magic react. Looking at the boy, he couldn't help but gape when he saw Harry practically glowing, his magic reacting to his anger. It was his eyes, however, that shocked Sirius the most: those green eyes were swirling, every shade of green and what even looked like black twisting.
"Harry, calm down," Sirius said, throwing up a privacy ward. Harry, however, was lost in his anger. Seeing this, Sirius did the best thing he could think off - he cast a water jet spell at Harry's face before closing his eyes and hoping the boy didn't kill him by accident.
Harry reacted immediately, turning his attention to the supposed threat. However, seeing Sirius, his mind caught up to him and he was able to regain control his power, forcing it behind his occlumency walls.
After a few moments, Sirius opened his eyes to see Harry sitting normally, the ethereal glow from his skin gone and the magic he had been humming with remasked. "I'm okay now," Harry said, his voice soft.
Sirius ran a hand through his hair. "Well, if I ever had any doubts about your story, they're certainly gone now," he joked.
Harry looked up and smiled, though it was a sad, little thing. "I want him dead, for everything he's done to me, to us, to everybody. The lives he's ruined and manipulated," he whispered.
Sirius let out a breath. "I know, pup, and I will stand by you. Hell, I will even cast the curse if you need me to," he vowed.
After a few more minutes, the pair regained their composure and Sirius felt safe to dispel the ward. Turning their attention back to the trial, neither noticed a pair of eyes staring at them in both shock and awe.
