Artemis, on the other hand, didn't as much as blink at the mention of supernatural. It wasn't the word he might have chosen first, but it certainly described well the things he was more than familiar with. "I am not a boy, I'm just small in stature," he said as patiently as he could manage. "And I can very well pay for myself." He might have claimed to actually be more than a human, but he'd rather keep his tiny traces of fairy magic secret from as many people as possible. No reason to invite trouble, especially since Butler wasn't there.
