ganga would never do something to hurt the singhs who helped her during her most worst period even if it means losing jagya ...she is a girl of values and tradition and thats what makes her ganga..only a serpent bites the hand that feeds..marriage is not between individuals but between famillies in india..So unless sumi accepts ganga ganga will not step into badi haveli..its very nice to see a mature jagya who values his family very much instead of running in a haste behind his heart...for this ...for sure sumi will change wen she sees her son is going for lengths for his family..even till sacrificing himself
