Urmilla forgets that kokila did not take the keys away from rashi it was hetal, also when kokila told rashi off it was not infront of outsiders her mother and just the modi parivar were there.
So where is the logic to all of this, Rashi forgets that she is a modi as well, she will also get insulted by all when they go to functions etc. But if urmilla does start to have a go at kokila the whole family will know that it was her who revealed it. i doubt if anything is going to happen to u and r but this time its is beyond the limit of disgust
