I think she has a right to be angry because Jai didn't accidently kill anyone(not that I believe she actually died from the car accident from Jai;s car) That person was her mother, her and her three sister's were motherless and Bani missed her mother's love and affection and that is why she is upset. I guess she just can't grasp that the person she loved most in the world, whom she lives for, is the reason her mother is not in this world. It can be debatable, but from a daughter's persepctive I can empathize with her, but oh how I feel bad for Jai, his hurting internally! đ
Keep smiling..
