i personally think if kokila shouts at gopi it becomes more negative regarding gopi n ahams relationship, as he said he is his mothers shadow so what ever mother says or does so does dikra. So hence i feel kokila does not want to be a obstacle in their relationship.
I agree there's nothing Koki can do at the moment and the right thing to do is get Gopi busy so she will stop brooding about what has happened. Ahem has already shouted at Gopi so there's no reason for Koki to repeat it. I also beleive that Kokila is biding her time she must know that Rashi is involved in this somewhere but no one is going to believe her without proof anyway as evidenced by previous kalakaries.I firmly beleive Kok ke dhimaag mein kuch chal raha hai she can't have changed in the last couple of weeks.Maybe she's waiting for the results to come out which will give her an inkling as to what exactly happened.
