I think her acting at this time is not really believable. HOw can someone who as lost and has a gun pointing at them not show any type of fear at all.
In Dulhaan (Sindoora who in my opinion is and was by far more evil then Kala ever can think of being and her plains actually worked vs. Kala's has always failed big time) even she had a scared and upset look and a i am sorry face at the end before she was captured and send away.
Kala needs to work on her acting a little bit.
