Roxie Lyon was romantically involved with Angela Montenegro, whom she had known since they attended art school together.
She was first mentioned in Mummy in the Maze by Amber Kippler , the senior investigator who helps find Angela's ex-husband, as "A girl named Roxie whose heart [Angela] broke in second year art school." In this episode, according to Kippler, Angela told Roxie she changed her name after it came to her in a dream. She was introduced in The Skull in the Sculpture after her boss was found in one of his artworks, with Booth questioning Roxie as a suspect in case she was involved with the artist until she revealed that she was gay. She and Angela started dating again and continued doing so until The Salt in the Wounds, when Roxie broke up with Angela because of her way of only living in the moment.
