Why lowest of low??? Trust me, methinks the Kapoors (Nikhila and Shiv, esp Nikhila) fall in that category. What is Gauri to Ipshita? Nothing much... Even then she's trying to make Gauri's last few days on the planet as easy as possible. It is a lil morbid, but I'm sure that Gauri has appreciated Ipshita's friendship. And all she's asking Shiv to do is make Gauri happy for whatever time she has left...
The lowest of low tag shud go to the other two, who knowingly threw Gauri into the fire. Nikhila, who Gauri treated as a mother figure lay the foundation of her funeral pyre? Can anything beat that?
