Asus honestly didn't think a single pistol and some bullets would get them that much money but he felt no need to mention that. So instead he followed Lenwood off the the ship and onto the island. When he noticed how empty it was he didn't trust it at all though rather than simply look around all the time he released ten hornets to do the spying for him, one at a time. He tried to do it with any of his crewmembers noticing.

The released hornets immediately set out to follow Asus' orders. Six of them headed of in the distance and the other four scouted the nearby area, all of them looking for large groups of people with weapons. Because of those order they completely ignored the girl that Lenwood would bump into.
