I don't understand that if Vivaan is searching for his mother then how come he only knows her name. I mean shouldn't he know about her family or her surname for that matter.
I also think that the lady in Soni kudi will be a relative of Vivaan's mother and not his mother because if she is his mother then whatever Vivaan thinks will be proved to be true.
I think she may be a orphan. But the point to think is she is missing and how meera and her family related to her . I don't think that lady maybe some relative of his mom
