Yeah, before the ODLH fight, he was basically saying that ODLH wasn't a true Mexican. All of this based of the fact that ODLH is massively popular in the US and caters to the US audience as well as the Mexican audience. ODLH always makes sure that Americans know that he's not just Mexican but also Mexican-American. Vargas basically was jealous that ODLH was a great success and sometimes people like Vargas feel that being successful is somehow the equivalent of selling out. Then what happened? Vargas throughout the fight was saying "Come on, come on, let's fight" and then ODLH knocked him the fuck out. haha, karma is a bitch.
