I think Anurag needs to focus on Shravan. No matter what happened, no matter how much he hurt him, Shravan is still his son afterall. He needs to sort out things with Shravan. I don't understand why he is ignoring the whole issue. He knows that Shravan knows the half truth about Apo*na. Anu should try to clear his misunderstanding. He also needs to accept Tanish for the time-being just for the sake of Vinit. He needs to talk to Shravan and find out why he did what he did.
I think Anu should tell shravan everything about his life. Afterall, Anu's life is an open book. There aren't any secrets. Anu should tell Shravan everything about his relationship with Prerna and how he made the same mistake of not accepting Sneha, how he unwillingly married Komo and broke Prerna's heart, and how he lost his love forever because of one mistake. Anu had once said that he doesn't want shravan to become another Anurag Basu. So now is the time to act and make sure that Shravan doesn't make same mistakes as he did. Shravan is his son afterall and he does love him. He needs to forgive shravan and try to build trust back again.
I don't understand how come shravan isn't with the rest of Basu family in Kolkata. Afterall he is part of the family, more so than Sneha in the sense that he has lived with them for 20 years. Moreover, how come Anu forgot about Shravan's b'day.
Anurag shouldn't worry about what Sneha or Prerna are thinking about him. Let them think whatever they want to. Anurag's first priority should be Shravan right now.
