may be Avtar could have also said something earlier when he know something was not right. He did have a sense that something was not right about Lipika but did not put a stand.
Just because he was the girl's father didn't mean that he should keep quiet. That is his fault too.
Actually, eveyrone should have said something.
Dhruv, Ginni, Dimpy, Dimpy's mom...
If everyone knew something was not right about Lipika why was everyone so quiet?????
And now look, the whole blame comes on Mr. T
