"Hmm..." The male watched and nodded thoughtfully after the illusion disappeared. That could be a slight problem, but hopefully not an impossible one. "How much is too much? Would something more neutral, like...shaking someone's hand be too much for it? Or...what else would be likely...?" He thought for another moment, weighing a few other scenarios. "Or maybe...what if you held someone's hand or something like that? Would that be too much? Would it work for a certain amount of time?" Perhaps it would be a bit much to ask for, but at the very least, he wanted to know how far the boundary could be pushed before they could run into trouble. There had to at least be some leeway for something like this, right? He really wasn't sure at the moment.
