Nothing is known about Reynaldo's life prior to or as the outbreak began, except that he lived in Tijuana, Baja California.
One morning, Reynaldo was supposed to deliver Oxy to Marco's supermarket in exchange for water. However, he discovered that his partner Francisco and his family have fled the community. He knocks on Nick's trailer to inform Luciana what happened, and that he would not be making the run without his partner. He is reassured by Nick that he and Luciana would make the exchange instead. Later, he attends Alejandro's speech with many other residents and is urged to stay vigilant and stay with the community or face death beyond the walls. After Luciana is ordered not to go on the run, Nick approaches Reynaldo and convinces him to accompany him on the run that night.
At night, Nick and Reynaldo sneak into the infirmary to gather the drugs to trade with Marco. By morning, they reached the supermarket and are brought to Marco to make the trade. While making the trade, he serves as a translator for Nick and Marco, and is horrified to see Francisco's family dead, having been executed by the gang. Back at La Colonia, he and Nick discuss on how they evacuate everyone when they are interrupted by Luciana.
Reynaldo is present for Alejandro's final speech to the townspeople, urging them to stay and fight the Los Hermanos. Eventually, he and the survivors all evacuate the town and head towards the border, covered in blood to avoid detection by the undead. When they reach the border crossing, they are attacked by a group of militiamen. Reynaldo and the other scouts open fire, but Reynaldo is shot several times and killed moments after he manages to kill one of the attackers with his shotgun.
