The energy that Ra's al Ghul placed in Barbara Kean turned out to be a beacon for the rest of the League of Shadows as they arrive at The Sirens club. After relinquishing it to a revived Ra's al Ghul, she assists Alfred Pennyworth in rescuing Bruce Wayne as she manipulates events that have her forcing Bruce Wayne's hand into thrusting the embalming knife into Ra's al Ghul. After hearing from Tabitha about Butch's death at the hands of Oswald Cobblepot, Barbara blames men for the troubles they have been dealing with and decides to kill the males from the League of Shadows that offered to follow her after Ra's al Ghul's defeat.
