Why cant Vinu call Ranvir

This was really heights that Vinu was calling Sadhna again & again, putting pressure on her to come back soon with money but not even once he thought of calling Ranvir. I know how badly everybody in the both the families wanted to give back Ragini "saari khushiyan", but he could have told atleast Ranvir & could have got some money .............as I am sure that even if Ranvir knew about Mamiji's operation he would not have told Ragini as he also wanted Ragini to win. Ragini on the other hand not once thought about her parents even after winning..............she knew that her mom was ill...(though she was unaware of the severity of the sickness)....but anything could have happened......isnt it her duty to call & check..........& I always thought that a girl's heart always pounds for her parents even when she gets married.
