Suchi, here is another possiblity.Assuming that gauri doesnt come out of the obsession (trying to win over anandi at any cost) and bears a child.Even if this might hinder her career and education for sometime Gauri might take this step feeling that her child will be a greater weapon over anandi and the singh's family.This child will be accepted, so eventually she will be accepted.
That child will have the legal rights over the singh's property even though the kid is a product of illegal marriage.Gauri will have no right over the singh's property but her child will have.Daadisa who always dreamt of a great grand kid...might forgiven them eventually for the kid.But dear gauri this does not mean that anandi will be thrown out...anandi will continue to be the beti of the house and will probably get a life of her own.
