Carlos Mariano, the brother of Raul Mariano, the man who raped McCall and shot Hunter, whom Hunter would eventually kill, (see Rape and Revenge) has come to L.A. to get Hunter for killing his brother. And just like his brother, is shielded by diplomatic immunity. The State Department man warns him not to do anything, because his country is a vital ally to the U.S. Hunter tries to reason with him by saying what his brother did and that he killed his brother in self-defense but is unmoved. He eventually abducts Hunter and taunts him first, eventually Hunter gets free and only wounds him. Hunter turns him in and because of what he did, the country can have deported. At the airport, he tries to make sure that he has given up his quest for vengeance. (thetvdb.com)
