In "Whistle Past the Graveyard", Aguilar and his fellow Federale stops Boyd and his crew in the desert, shaking them down for $2,000 and confiscating the van filled with the bodies of Johnny Crowder and Rodney Dunham's men that were killed by the Crowes during the exchange.
In "Fate's Right Hand", Raylan goes down to Mexico to visit him at a bar for information about the heroin smuggling and the dead body of Johnny Crowder. Aguilar refuses to cooperate, insulting Raylan for having no power in Mexico and tells him to get out of his town. Raylan waits for a drunken Aguilar to come outside and climb into his police car, slamming into the car with his own vehicle and apprehending him. Aguilar is sent to a Mexican jail but does give Dewey Crowe's name to Raylan.
