In Opening Night, Amancio wakes him up and he tells him that Santanico has left. He is told to bring her back and he exclaims that it's time to regulate. He goes outside and finds a car that he can use. He finds a cassette and puts it in, and likes the music that is playing.

In In a Dark Time, he is stopped by the Mexican Cop and asks if he has seen two brothers, to which he says yes. He then whips out his gun and shoots the cop's hand off. He then walks over to him and proceeds to cut out the cop's eye out and sees Seth. He is pleased and drives off, leaving the cop on the ground. He then shows up at the Mercado and shoots Rafa through the throat and then tries to shoot at Seth, but instead gets La Matrona and kills her. He then confronts Seth and demands that he help him find his brother and Santanico, and declares that he doesn't need Kate and is about to kill her, but Rafa shows up and distracts him long enough for them to escape. He goes after them again and Rafa sacrifices himself while fighting The Regulator so Seth and Kate can escape. After they leave and Rafa burns to ash, The Regulator gets up and watches.

In Attack of the 50 Ft. Sex Machine, he appears as a drug influenced hallucination to Seth.

In Bondage, he grabs Nathan's hand and then cuts his ear off and proceeds to eat it. He shoots a large hole in the laundromat where the worship room is and goes after Santanico, who puts up a fight and kicks him, which temporarily gives her time to escape. He follows her outside and when she takes off, he puts a toothpick in his mouth and looks. He goes back in the worship room and when Carlos tries to break a deal, he tells him he doesn't make arrangements, he regulates and smiles.
