Aryan is shown as this sharp shrewd guy who reads through people and reads between the lines.... Foresee any hanky panky behaviour and action from just about anyone.... Family or dushman or any random person
Then
How does he not see through blue aunty and her schemes???
She gives around fake jewellery an fake affection and quite on the face abuses to anyone then how does he not see their planning and plotting and put them in place or atleast watch over them
Keeping an eye would have saved his random almost marriage with doll chick ... Even save his mother and sister from insult for a situation where it is not their fault.
