I feel tht it was DV as she supported his son in all and have to say she also had a big hand in bringing DV AND AMOLI together! if she would not have helped to plan and take part on tht drama of ranvir thn amoli would not have married him and be with him in the same house.
I really would have loved to see more of Sunanda, the biological mother of Amoli, they just kind of made them go out of the map nd it was kind of unrealistic :S i found just this thing a bit wird in the story otherwise it is PERFECT :)
