He flinched when he saw Halo begin to relax, wondering for a moment if this was a foolish thing for her to do. Indeed, it was best to remain relaxed, but he often forgot that too in fights. He was all energy and anger, coiled too tightly to remember to relax and give his aching muscles a rest. On the other hand, that could have easily been a trick and he could have feinted and taken her off guard when she was relaxing. He supposed he could only do this because he had earned some of her trust – somehow – and that she would have otherwise been more suspicious had he truly been an enemy out for blood. He nodded once to himself, satisfied that he had muddle through this problem.
Hybrid gave her an odd, confused look when she thanked him. He wasn’t sure why or why she had felt it was necessary, so he just narrowed his eyes and shrugged in response.
“Sure,” he grunted. “Keep practicing,” he added. He wondered if there was anything else to add, but couldn’t think of anything. He frowned when he noticed her lower her head and he let a low, disapproving growl rumble in his throat. He didn’t like it. He would demand it from others he disliked, but never from one he didn’t dislike. He shook his head and then took a step back. He glanced around, shrugged one last time, and then trotted away.
