I wasnt aware Talia was
that heartless. I mean I knew she wasnt a goodie good girl but I thought she cared for her son at least.
Now she suddenly says he is a bastard and no second thoughts of killing him.
Also I dont think the real Talia would want a broken Batman. The reason she loved him because he was the strong minded Batman. Why would she be interested in a slave
I think the Talia who were in Batman Arkham games who sacrificed herself for Batman at the end was closer to real Talia. This Talia seemed too simple and two dimensional.
