Sachin on how, why and when pregnancies occur in the movies:

It would have been interesting to see the moral and ethical dilemmas Milli is facing while waiting to blow her body up. But Sivan comes up with an easy way to aid her decision making. He shows Milli getting pregnant after her first and only sexual encounter (of course) and that forces her to think about about life vs death issues. If that pregnancy was not going to easily resolve matters, Sivan also adds a situation with a grandmother in a coma. We are told that the woman has been in a coma for a long time but anyone watching Indian movies through the 1990’s (or even 80’s) would know that the woman would wake up during an appropriate time ordained by the script. Sure enough, the grandmother grabs Milli’s hand in the climatic scenes.
