Since Cv's are showing the concept of surrogacy in the show,I felt Shweta will not be a surrogate mother in the present circumstances .Surrogacy is a carrying and delivering a child for another couple or person. This woman, the surrogate mother, may be the genetically related or she may be genetically unrelated to the child.In our story Shweta is not genetically related to the child or Indira
Shweta is a surrogate mother if she carries Inshi child and later handit over to INshi.But things are happening different in the story.Rishi is marrying shweta so that she doesnot be a pregnant without marriage.Moreover Indira is in coma,cv's are planning 6 yrs leap.So if in these 6 years the child will be born .Shweta is the one who will take the labour pain and is the one who raise the child,then legally,morally child belongs to shweta and Rishi as they are married and they are parenting the kid evn though shweta not a biological mother.
Law grants the child to shweta bcoz Indira has been away for nearly 6 yrs frm raising her child after surrogacy.The reason is there is no legal documents between INSHI and Shweta.Moreover Rishi marrying shweta,Indira health condition due to which she could not take up parenting of child.In many cases,law ethically,morally and legally gives the rights of child to the couple who are parenting the kid
So Shweta will no more be a surrogate mother but become real mom in future
So i think after the leap,this will be a major track in the show.So much emotions n drama on who is the mom of the kid and with whom Rishi must stay.
Anyhow this is too early to judge what will happen in the show.HD cv's are always unpredictable.
