Luciana was a resident of La Colonia, where she was a combination of recruiter and supply runner for the community. She led the group that rescued Nicholas Clark when they found him in the barber shop. She has been described as someone who is 'testing' Nick. This would seem to indicate that she holds a position of trust, as she is allowed to evaluate possible recruits.
In the third season, she was briefly a resident of Broke Jaw Ranch, but she left, believing it to be unsafe. In the fourth season, Madison and Nick managed to reunite with her. After the fall of the Dell Diamond Baseball Stadium, she witnessed Charlie kill Nick. She then joined Morgan Jones' group in his quest to help people.
Not much is known about Luciana's life before the outbreak, except that she probably lived in Tijuana, Baja California, or its proximity with her parents and brother, Pablo. Her father died of unknown causes long before the apocalypse. Some point before the apocalypse, Luciana had worked at a factory with her brother Pablo.
Immediately after the apocalypse broke out, Pablo and Luciana lost contact with their mother. Pablo went searching after her, but eventually found her deceased and reanimated. After they confirmed the death of their mother, Luciana stayed with Pablo and sought comfort from him. At some point after the outbreak, Luciana and Pablo joined La Colonia, with both of them eventually serving as scouts of the community. Luciana even reached the position to be the right-hand woman of La Colonia's leader, Alejandro Nuñez.
Showrunner Dave Erickson describes her as a "badass soldier" and an "orphan of the apocalypse." She and Nick form a bond, but she is not shy about putting Nick in his place.
Luciana and Nick have an increasingly close relationship. They confide in each other and spend a lot of time time together. At the end of the episode "Pablo & Jessica" they kissed in a manner that seemed to suggest Luciana was going to stay for the night. In an interview, showrunner Dave Erickson said while they will have a bond, Luciana will keep Nick in his place.
Francisco was part of the group that found Nicholas, he defers to Luciana.
Alejandro and Luciana have a close working relationship and have been in dangerous situations together. She defers to him. In "Pablo & Jessica" he tells Nick the story of how Luciana rescued him the day he was bitten by one of the dead. The story he tells him fits with the story told Nick by Luciana.
