Gordon's daughter was a young girl when Two-Face kidnapped her mother, older brother, and herself.
History[]
In The Dark Knight Rises, her mother divorced her father and took her and her older brother away from Gotham City to Cleveland. Nothing more is heard from any of them.
Behind the scenes[]
This character is never named, but it can be assumed that this is the Nolan version of Barbara Gordon II. If so, this version of the character never became Batgirl or Oracle.
Also, while the character's age is unknown, the actress who played her, Hannah Gunn, is younger than Nathan Gamble, who played James Jr, so it can be assumed that the character is also younger.
