What bothers me is how she supposedly can't talk. I mean the premise of what her dad wanted to make her makes very little sense when you think about it. Especially since children learn though observation. I honestly think a good twist on Orphan would be if she could talk but not when people were around. The reason I like this idea is I just hate how her parents just talk to her but never get a good insult thrown back at them. Like Shiva she acted superior to Orphan when Shiva lost to Caine and was spared only because she agreed to give him a child.
I just really like the idea of Orphan being able to speak and shocking both her parents by saying "You are both worthless idiots and the only reason I never killed either of you is because I don't consider you worth killing." Then as revenge or all they've put her through Orphan beats them both down like dogs and steals the title of Lady Shiva from her mother while having no loyalty to the League of Assassins or Shadows.
I just think humiliating them and taking everything from them would be good payback for her.
