In one of the earlier episode Bani tells Pia that she doesn't how things were between their parents and Rano said that she dosen't really remember her mom that well...But if she died 7 years ago, that Rano should have been around 12, and 12 is not a young age... Also, why would thier dad lie about their mom's death, why not just tell them about the accident insted of saying that she was very sick.... let me know your thoughts
