Stephanie Brown is the estranged daughter of Arthur Brown.
At some point, Stephanie graduated from MIT. While there, she joined a club where deciphering code was a hobby.
Sometime before or during 2016, Stephanie became aware of her father, Arthur Brown's activities as the criminal "Cluemaster". She left an anonymous tip to Sophie Moore, an agent of Crows Security, which subsequently led to her father's arrest.
In 2021, Stephanie's father broke out from Blackgate Penitentiary and asked Stephanie to join him as he began targeting Sophie, mistakenly believing that it was her who single-handedly solved his clues. Stephanie said no. As a result, Stephanie was captured, covered with hand-written code as she was unconscious, and held in a glass tank, where Sophie, Ryan Wilder and Mary Hamilton freed her by shooting the various bullseyes in front of the glass.
After being rescued, Stephanie aided the trio and Luke Fox in finding her father, Arthur. Upon discovering her father's code, she made Luke unconscious and found her father in their first home. There; she revealed to him the truth about his imprisonment, so Arthur knocked her unconscious, trapping her and himself in a car to die, but Luke managed to find her and save her. Arthur was arrested again and Stephanie thanked Luke, kissing him goodbye.
