Special Agent Jonathan Cross

 Agent Cross is what most people refer to as a spook, one of the Men in Black. He is almost like an entity sent from 'the government'. Perhaps during one investigation he says he is with the NSA, on another he claims to be part of the ATF. It is never quite clear which organization Agent Cross truly works for. What is clear is that he has a vested interest in keeping anything supernatural from being exposed to the public, and he has a great deal of influence within the justice system of the United States.
