Karishma's role in getting sai out of House

As karishma swear in amay track when kaku punished her that she will make sai leave d house.

I feel somehow karishma will bring this forward by revealing sai & UM both lied to Virat as sai remain out whole night & pakhi didi will add mirch masala . It will definitely pinch virat.

Ek baar jhoot bolne ke baad agar vo pakra jaye to phir uski koi baat pe asani se yakeen karna mushkil hai.

No I dont think so bcoz karishma never knew sai spend one whole night outside.only ninaad ,omi ,kaku and usha mausi knew.

But I was thinking just the opposite bcoz karishma is the only one other than sai who overheard the kidnapping conspiracy .so I think she may blurt out some thing to mohit and mohit will sow some doubts to virat regarding kaku mandalies vile actions
