Nate appreciated the fact that rat seemed to be able to speak english, so at least he wasn't a rabid animal biting the truck tire. In any case, a man biting a tire was a lot more inexplicable than a full truck leaving a warehouse. "All I got to go off of is your word, and I don't like to trust people who try to chew on tires. How would you know these guys are up to no good, have you looked at the shipping schedules or something?" He stepped in the path of truck, hoping to head it off in case anything else happened. It would've been useful to have MeChip in a situation like this to find out who this guy was, but he didn't want to pay for it or take on the risk involved in having a chip in your brain. Later he'd do an internet search for something like "who is this rat man millennia city weird guy bites tires" and hope to get some results.
