She was just scared that, Jasleen might take her name for supaari which is why she behaved like a looser as this is the word she called Jasleen, but Jalseen is bound to do task after getting disqualified, Srishty cannot stop her form doing it.
Even Surbhi was playing after getting out, Megha gave supaaris many times, but Srishty cannot DARE to say a word to them as she is so scared especially with Surbhi.
It is really funny the way she is scared of Surbhi, her tone, words, and behavior changes with Surbhi, she acts like a soft spoken person when she is talking to Surbhi.
She knows Surbhi is a difficult person to handle and her aggression is beyond Srishty's imagination.
I am praying for a fight to happen between Surbhi and Srishty, then we will see who gets aggressive first.
Her friendship with Surbhi is because they both hate Jasleen and Dipika,so enemy of an enemy is a friend and Srishty only makes friends with benefits.
