I think what the TC article says is more likely than the future track as reported by Telly Buzz.
This article does not say anything about Ankita's miscarriage and I myself do not believe that it will happen. Ankita's child is the only connection that she has with Naren and therefore he/she will live. PR CVs will not kill Ankita's link to her past as that will mean closing that particular chapter of her life.CVs just wouldn't do that as I am sure that they will bring back Ankita's past to haunt her when she will be the happiest in the future.
I guess it goes with Balaji's style to make Ranvijay fall in love with Ankita but she not reciprocating back the same feelings. An ideal BT heroine falls in love only once and that man is her god. Ankita will continue to be in love with Naren and writing letters to him. I guess Ranvijay's mom will insist that Ankita marries him so that her child gets father's name in the society.
Differences between Pari and Naren will increase as Pari would want to focus on her career and their business' growth while Naren would want to concentrate on the family. Probably, Pari and Naren will realise that they are not compatible and in the future might even separate.
Ankita will one day come at a crossroad where she will have to choose between Naren and Ranvijay. One, a man whom she loved and had a child with, and the other, who came into her life when she was all alone and became the father figure to her child. I hope she chooses the latter.
