I don't know why some fans want meghna not to know about karan problem now. I don't feel meghna will get angry over the issue if she comes to know about the truth (Meghna will get angry on naina for hiding the big thing from her and not for karan problem). I think Sure Meghna will help Naina, Karan is not only her sister husband but also her devar so she will come up with the plan cleverly to expose sandhya amid family members. I will feel if meghna comes to know about not only karan problem but also sandhya is the main reason for karan problem, because it will solve many problems. Already Meghna and Naina come to know about that NK and Sandhya have planned Shradha name defamation and also realized how stoop they have fallen. This dance competition has highlighted important points and also brings twists among both the couples that they will never hide anything among each other. The karan's truth amid meghna will bring sisters together and will also help to plan them accordingly. Karan will also understand how Naina family is supportive among each other because already he have felt same thing when he have gone for pag phere Rasam. Not only this, sisters will help the brothers bond also strong. By that we will get to see teasing of both the couples and their romance too and Meghnal will find their siblings have started to fall in love but not realized. I feel Meghna will help Nirmala to gain her self confidence and to stand for her swabhiman and Naina will help karan to love himself and also to gain his confidence. If sisters succeed in these things than Sandhya and NK will be off. When Nirmala starts to talk with Nk with a strong attitude then he will be off and Karan attitude will show Sandhya true colors among family members
