It ends in murder and the con man is left to help Five-0 find the killer. In the end they don't have to look too far.

Besides wanting their money, he thinks they are upset because he killed the other two henchmen. He learns they don't really care about the dead guys, and that his debt has been paid and that he killed the two men for no reason. Adam being the upstanding guy that he is, turns himself into the police with a surprised Kono by his side.
