Ernesto is a former parolee of Henry Mitchell's. At one point in time, he was in a relationship with a woman named Tina, who was another parolee of Henry's. However, while Ernesto went off to build a better life for himself, Tina was unable to do the same and the relationship ended.


Unknown to Ernesto, Tina became pregnant before they broke up and gave birth to a son, Ramon. When Tina was sent to jail, Henry struggled to find Ernesto to prevent the boy from ending up in the foster system. To buy himself more time, he brought the baby to Paige Matthews while he looked for his former parolee.

However, with a magical emergency around the manor, Paige could not protect Ramon and instead used a photo of Ernesto to scry for him. When Henry met with Ernesto in his office, he revealed the news that he was a father. Ernesto was not sure if he could be a father and did not know how to handle a baby. Henry encouraged him to try so he could prevent his son from falling down the same path that he once followed. Ernesto then left with his son.
