Maybe at the party, as jigs plans, she may insult Bani in front of Jai, jai may even insult her after he finds out but the doctor may say the mrs. Bani walis isn't pregnant, miss Anu walia is or summink like that. And from there Jai may really start to have strong feelings for bani, coz he might think that she went through all that insult just to save his family reputation......and we all know from the begining that Jai really prizez his family name.
In the article it also says that Jai stands by bani after rano and sahil elope and he cannot distance himself from her, she is the one keeping his family together or summink like that.
so that was my theory, wat do u guyz think.????
