Taking stand doesn't only mean crossing Dadaji verbally.. Parth is a guy who is born and brought up in a conservative, joint family. He doesn't usually directly oppose anyone in the family or talk discourteously to them. But at the same time he never fails to support what he feels is right, through his actions. In this case also, he preferred to bear all their angst silently. Somewhere, he and Shorvori were also at fault in hiding the surrogacy and Shorvori's pregnancy thing from the family. But that didn't stop him from leaving the same family for his wife and baby's sake. If he couldn't stand for his baby, he would have let Teni go.. But he chose to leave the house and the family instead.
