As much as he might be having a worse day at adjusting, Percy was not about to blame his ridiculousness on that. He was smarter than that. He had taken a course of action and now he was getting the consequences of said actions. When Marguerite responded to him, at least he understood where she was coming from. No doubt it was how she'd felt the entire time he'd been playing the fool and remaining distant from her. And he knew there were more important things to deal with here than clothes. There was a war, and while he was still sort of grasping the concept that demons and so forth not only existed here but could hurt people and so forth, he knew the value of remaining focused on the task at hand.
Going to the camp to learn how to fight the supernatural beings of this world was a step in that direction. Percy was looking forward to doing that because even with the supernatural aspect of it, it was something familiar to him. Getting out and doing something like that would no doubt help him greatly. But then he'd gone and made the statement about clothes and carried on being ridiculous. Perhaps it was because he was still somewhat used to putting on the facade when something was bothering him? He wasn't exactly certain on the reason behind it, he just knew he had been ridiculous on the matter.
It really wasn't that bad to reuse things. It was probably more of his having to have multiple tools at his disposal talking than anything. All the costumes he'd used while sneaking through France were all just that, tools. But the clothes he'd worn while at home were most certainly not tools. Those had, for the most part, been part of his position in society and keeping up with the fashions of the day, really.
"I wouldn't let you sell yourself," was his quick response to Marguerite's words, and there was passion behind it. Because while he might be used to having a full closet there was no way on Earth he would let his wife sell herself for any reason. "There is far more at stake than clothing, I know. All of our lives and the fate of this entire world."
Which, all right, so that hit against another thing Percy didn't like. Human foes he could handle. He could fight human enemies. But the supernatural? Those kinds of enemies frightened him because he didn't know how to fight against those. The camp would help him learn that, but even then, he was still an ordinary human being. Though currently Percy was bit more afraid of Marguerite having a knife in her hand and possibly lashing out at him. It did make him nervous, though he knew she wouldn't actually hurt him with the knife. Well, not on purpose anyway? Still he rubbed his chin and leaned back against the wall opposite where Marguerite was chopping vegetables.
"There is absolutely no reason for it. But perhaps it's because I don't like not having tools at my disposal that I can use to protect us. I like having options, and right now there are not many. Though obviously I know going to camp and learning how to fight the things in this world will do just that."
