Yash's mother (also a dadi) does not twinge and tells lies with a straight face. So the picture that is being painted is that jaddi-pushti families, who stick to their family values and believe in joint family system, the mothers is there to tell all sorts of lies and playing all her cards to break her son's marriage. Talking about the values, the youngest bahu still goes to her job of RJ and the jaddi-pushti family does not mind it.😛
