The OSS now has a full child spy section, of which 13-year-old Carmen Cortez and 10-year-old Juni Cortez have become agents. Even though they were the first of the new Spy Kids Division, they are not considered the top spy kids, and soon they face particularly difficult competition from Gary and Gerti Giggles, the children of double-dealing agent Donnagon Giggles, whom Carmen and Juni helped to rescue in the previous film. It is shown that Carmen defends Gary, and has a crush on him, which strains her relationship with Juni.
