"As do you have a penchant for misrepresenting another's words," came the snapped reply. This thing, whatever it was that Simon couldn't fight off, was starting to aggravate Severus. He wasn't a patient man normally. In the face of this odd back and forth, he found himself wanting to know, and though that knowledge might later come to great use, he wouldn't let himself fall into this thing.
"Discipline must be finely honed, not just used raw. It requires a desire to block your thoughts, no matter what they may tell you. Therein lies true power over your mind." Severus believed that above all else. As disturbed as Simon appeared to be, even he could use his mind to his advantage.
He observed as Simon started counting out his payment. Perhaps this strange encounter would be ending soon; why that should instil a sense of unease within Severus, he didn't know nor did he want to analyse it, not until he was away from here.
