While they were in Meerut some how Ganga and Meera(Jai's current wife) met then later on Jai met Ganga but he still didn't know that Ganga was his daughter. While all this is going on Jai met up with the owner of the land he wanted to buy the owner told him he would not sell his land because the current residents living on his land were very dear to him(Bani,Ganga & Maasi)so Jai was going to meet up with the residents to make a deal with them but the owner of the estates wife who is very greedy for money stopped him.She brought Jai to her home and she told him that the estate was in her name and she could sell it if she wants.So she sold it for 25 larks but Jai Walia paid 1 crore for it.
