Dolly is spoilt child.Her relationship with her mother has always been v cold and formal.The reason behind this is the authoritative and commanding nature of Vasu....even with her husband her relationship is not that well.
She takes the lead and make big decisions herself.She's not very open and close as mothers are with their daughters.She has kept a distance..(no idea if she had always been like this).
Sadhna's good nature will definitely influence the ppl of Rajvansh in a +ve way.
