Por que Talia Al'Gul teve que perdoar o pai dela?

Talia se ressentiu de Ra's Al Ghul porque ele excomungou Bane.

Ra's Al Ghul excommunicated Bane because he reminded him too much of his wife, Talia's mother, and the prison she was kept in because of him. Talia loved Bane (in a fatherly sort of way), and so when he was excommunicated, Talia acquired a resentment towards her father that did not pass until his death.

Quando Bane foi excomungado, Talia saiu com ele. Porque eles ainda mantinham os ideais da Liga das Sombras, eles se tornaram as cabeças para cumprir o legado de Rá depois que ele morreu.

Dentro do contexto do filme, Talia se refere ao fato de que:

Her father left her mother when she was pregnant with her. And her mother ended up the one who was imprisoned for her father's mercenary work. Talia was left to grow up in the pit with only Bane as her protector.

Tanto quanto se Talia foi banida com Bane, o filme não está claro. Mas Bane faz questão de dizer que, como o Ra's Al Ghul está morto, ele é a Liga das Sombras.

(really Talia is leading it)
