Julia Golden was a researcher at Global Dynamics. She had a crush on Douglas Fargo and eventually resorted to extreme measures to attract his attention. Using her background in genetics, she was able to alter her form and her DNA in order to appear as Deputy Jo Lupo (whom she had previously described as "perfect"), thinking that it would help her win Fargo's affection. After her deception was discovered she was allowed to remain at Global Dynamics - albeit on probation ("Your Face or Mine"). Later in Season 3 she and Fargo are still dating ("What Goes Around, Comes Around").
