Sasuke's annoyed expression shifted several notches over to a sort of outraged confusion when Aidou justified what he'd done -- not least because Sasuke could see his point, that there was a necessity to test an ally, and that meant that Sasuke was a weak link now. Which he'd never been and didn't plan to be, and he hadn't been the weak one in the excursion last night, but then again, Sai was an unknown quantity even if he was professional, and Usopp didn't seem terribly combat-experienced ...

But if Aidou thought Sasuke was just going to accept a test like some chastened genin and move right along, he had another thing coming entirely.

"Do you want to fight me?" Sasuke demanded, eyes narrowed and arm still raised, for defence or attack no longer clear. If there was one thing he'd always been able to do as a ninja, it was judging distance by sound, and if there was one thing Aidou hadn't stopped doing, it was talking. "If you continue to present this sort of irritation, I will take it as a sign that you do."
