Of course it would change, wouldnt it change for you? It didnt have a direct effect on her, but according to Ranvijay (and since it would have had a direct effect on him) he forgave Jai.. then why should Bani hold any grudge? Yes since it was directly connected, it is harder to digest.
***It would definitely would hv made some sense, if she had felt atleast something for Raashi and Rohit! When JW said thats his biggest mistake, she didnt allow him to speak and said that no no, its just an accident! When she could make him faultless for Ranvijay's case, then she should hv atleast considered or thought about it when it turned out to her mother! Just labelling him a murderer and also making him responsible for the destruction of entire Dixit clan is not rite correct?
