Grey had nothing do. It was almost painful. And with Ammie around, he couldn't just sit around. Her very presence would spread law and order. he shuddered just thinking about it. All his hard work to this point, all his carefully layered chaos was in danger of being scattered due to her annoying lawful aura. And the worse part, she might not even be aware or it! It could just be a sub-conscious effect that she had to her name. Which meant that he wouldn't have legitimate cause to actually be mad at her. Which, stangely enough, was causing his own chaos levels to rise. That gave his pause. In the conflict between order and chaos, the conflict itself strengthened chaos, even as it weakened it. Which was way chaos was the better element. But he couldn't let his mental state get in the way of his regular interactions. Like the Tsundere/Luka problem. Tsundere and her sporadic chakra, or Luka and his reliable white magic. Tough choice. Not.
"If you really want Luka, knock yourself out," Grey shrugged. He lay down on the deck and let Luka do his stuff. Nice reliable white magic. He did raise an eyebrow at Luka's new wings. Maybe they were tasty. "Nice to know that you found your calling," Grey commented as the spell did it's work. "I guess I'll have to kick my own role into high gear to cover up for your absence," he said lightly. "And Tsundere didn't scare me. She just had me put up my guard. I read (read?) Naruto manga, and watch (watched?) a couple of the episodes. I know what she is capable of. I'd rather not give her the opportunity."
He rose to his paws and rolled his shoulders and shook slightly testing to see if everything was working properly. White magic was good. Even better, since Luka asked to heal him, it technically counted as a favor he was granting. Nuances of language were a wonderful thing to exploit when making deals and contracts.
