In the great revelation of The Dark Knight Rises, we are shown it was Talia who escaped The Pit, then brought her father back to rescue her savior, Bane.
However, considering the fact that Talia was born and raised in the prison, how did she know where to find her father or who he was?
One can assume that her mother instructed her on her father's name and nature of his profession, but it is reasonable to believe that her mother didn't know where Ra's was since her incarceration?
