Asimov is a beta-male loser who only gets his confidence by using the red eye he's supposed to be selling, he also is fueled by his own ego, and tries to act cooler than he is, so make that come through in your performance, his voice should be akin to what you'd imagine a small time, baritone crime type to sound like, but do not go too cartoony with it, we still would prefer if it sounded like he was somewhat of a threat.
