Purvi's son

Yesterday I was going to post that I think Purvi had her second child (a boy) but perhaps he was born so prematurely that he has some develpmental problems. Perhaps he is in a special school and that's why we don't see him. Also, it's possible that Arjun may not know that his son was ever born.

Now today they mentioned a Rohan and I'm thinking that perhaps my theory might be true? What do you think?
