It's just...people tend to overlook you easier when you look nonthreatening, and they do that." Almost camouflage -- he's just some skinny little guy with glasses. Not anyone to worry about. It's helped with the copious amounts of eavesdropping Koby's done, both at home and since arriving in Abraxas.

Then, squaring his shoulders, he nods. "I'm sure. I can keep up, don't worry." Even if he has to push himself.
