“Sound waves!” Dumas exclaimed, clearly delighted by the revelation.  “I wouldn’t have guessed that in a million years.  Absolutely amazing.”<br/><br/>Leaning back in his chair, Dumas folded his hands across his stomach, his face wearing the same satisfied expression as a diner after devouring an extremely good meal.  “You know, DEE could probably run some harmonics calculations for you, if you want.  Maybe he can figure out that resonance frequency you’re looking for.”  A playful leer curled Dumas’s lips as he winked at Chester’s avatar.  “And then to pay me back for asking him, you can come up here sometime and try to find<span style="font-style: italic">my</span>sweet spot.”<br/><br/>Dumas rarely asked personal questions.  It wasn’t because he lacked curiosity about his fellow humans.  It was just because people always interpreted that sort of thing as an invitation to ask him personal questions of their own -- the sort of questions that he usually didn’t want to answer.  But tonight, he was in a contemplative mood.  Slowly, the leer faded from Dumas’s face, replaced by a more serious expression.  “Ches?” he began.  “You’re smart.  You probably could have done nearly anything you set your mind to.  So why this?  Why stage magic?”
