It cant be bani's mom that got killed by that car accident because:
If Bani's mom died in tht car accident on June 29th seven years ago then when the mechanic mentioned the date...Bani should have clicked if her mom died in an accident!!! (It is a major flaw in the serial if Bani didnt click accident date and her mom's date to be same)đ
Secondly, if jai and Roshni killed Bani's parents that night and gave Bani to Kiran & her husband....if Bani is now 23 (in the serial) then seven years ago she would have been 16 years old. A 16-years knows if she lost her parents and was adopted!!!
Due to above mentioned reasons....the theories about the "raaz" do not fit in!!!
What do you say..........
