i am saying she is not pretending because:-
1. if she can go to police station to make complaint about aakash burn, why cant she do the same thing to find out or protect arya..
2. if she send arya out of SM do you think they will be save from ishita...if she wanna kill arya she can do it any where
3. when yash got shot, g3 did behave like this..all she care is my blood..my son...nothing else..
about the spoiler g3 might know that arya live in danger and someone is plotting to kill them..maybe is in the up coming track...but i am confident she is blind with aakash love now..
