Nearly every action of shitall is to show khushi..

No chappals please, but i think shitall is using khushis innocence an takig advantage...
Like for example:
The phone rang at the right time that shitall and aarav has to leave home so khushi told them to stay...
She purposely avoided talking about aaravs dad and made a big hoohaa about it when he was mentioned...the raizadas didnt know her life story she could have made anything up...
Everytime aarav has his tantums its infront of the family...
And today, didnt shitall herself remind aarav that fathers day is coming up so you need to so blaady blah...but still to make a show out of it she asked aarav purposely why and what not...

And that time after going to the golden cafe and aarav going missing, she went to put aarav to sleep and said stuff like if you have me do you need anything else and stuff???
She knew that khushi was watching them...
And the way she took out a breath of relief after khushi ripped he first dna report, cause she had not enough time to change and alterate it to positive...all links up...

Shitall is here to shit all things up...
