When Carmen's crimes caught the intention of Interpol, Julia Argent and her partner Chase Devineaux were assigned to look into her crimes in hopes of catching her. While Devineaux focused on the case with a single mind point of view, Julia works on a profile to help her better understand the mystiques Carmen Sandiego. Since Julia is curious as to why Carmen wears a bright color that makes her stand out, before and after she commits her thefts, along with Julia wondering about the places that Carmen as robbed across the world. Until Julia's partner made contact with Carmen in Poitiers, France and because Julia is still a rookie Devineaux didn't let her take part in the chase for Carmen. Even though Julia staying behind to examine the scene of Carmen's latest crime did allow her to uncover the hidden pattern that has Julia see Carmen in a kinder light. Julia tried to tell Devineaux of her discovery of Carmen possibly being a thief who only steals from other thieves, but he wouldn't hear her theory out while Julia choice to hand onto to.

After Julia was hired by A.C.M.E. to find Carmen and uncover her link to V.I.L.E., Julia continues to learn a bit more about Carmen Sandiego's character and motive as someone who respects history like her. Even though Devineaux has A.C.M.E. to believe that Carmen is a villain Julia is able to spot the small things that says the opposite. Carman and Julia meet one another in "The Chasing Paper Caper", where Carmen give Julia the nickname "Jules" while Julia shares her historic passion with Carmen. Julia didn't realize that the girl she talked to was Carmen Sandiego until she found the stole Magna Carta on her train car seat, their earlier conversation had told Carmen that Julia is with Devineaux and that she can still trust Julia to return the Magna Carta on her behalf. When Chief commended Julia for recovering the historic documents, she tells Chief that she didn't acted alone in which caused Devineaux to be upset with Julia when he accused her for being Carmen's new friend.

Even though everyone at A.C.M.E. is saying that Carmen is behind Chase Devineaux's kidnapping and the state they found him in, Julia refused to believe Chief's clam. Since their hunt for Carmen has taught Julia that not everything is what it seems and as she sits by her sleeping partner's bedside, she asks him to tell everyone that Carmen is innocent when he wakes up. Devineaux's stubbornness, however, has him giving Julia and A.C.M.E. the answer that is the opposite to the one she was hoping for, as Julia begins to believe that Carmen is indeed a villain they need to take down. Julia practices the words she wants to say to Carmen when she arrests her, and when the moment she practiced for came during Fashion week in Italy Carmen surprised Julia when she enlists her help to prevent the theft of four historic gowns. With her faith in Carmen restored Julia tells Chief that instead of arresting Carmen they should recruit her.
