Eryx watched carefully, this was something new, something actually interesting. He watched the girl getting tazed, ignoring the action itself but instead the tazer. He watched the little volts, seeing the true nature of them up close, how they didn't zap forward as all were taught but rather how they curved throughout the air. This entertained him, seeing such a thing in it's purist form. Before he'd just flip a book and read it in a moment, but now it had been useful, it showed him something only he could see and he enjoyed it. 

"Why are we here?" He asks, moving back to current speed when the event was over. As much as he liked the experience he also found a flaw, if things were moving that fast he'd slow them automatically, even if he didn't necessarily plan on it. The instinct could also save him, he thought. In an ambush situation he'd need it to trigger like that, he'd never be caught by surprise.
