I am not sure if marrying Dhaani and Viplav without first solving their family problems and KT and DT overcoming their prejudices against widows, this marriage is not likely .
I would like to see Dhaani and Viplav a little stronger in their bond with each other so that they can face adversities that are going to come their way.
KT and DT have to be dealt with first. Knowing their real truth Viplav is going to be devastated and bringing Dhaani into their house will just be the same tug of war between Saas Bahu.
If Viplav does not know about his family then there will more MU between them as married couple because Viplav is going to be torn between his wife and mother.
So hope CV's solve their problems first before pushing them into their family fire.
