Sehmat & Her Son! So Many Question Can Someone Answer?

Can someone focus more light on Sehmat and her son? Don't you think her son really deserved at least few minutes of appearance in the film, not only those 5+5 seconds at the beginning n ending of the film? The people who can't read English probably would not even knew that why the camera focused in that particular guy on the deck of the ship! & would get confused thinking that what happened to her baby n was it a boy or a girl!? I just started reading the book but can't hold my excitement to know more about them, I read the pages before the start of chapter 1 & the epilogue, from there it seems they shared a good bond but in one para it's been written "his mom came into his life when was merely seven now what does it mean? Till seven with whom he lived? Since Abhinav is his foster father according to epilogue so was he with him till seven? & where was his mom till seven? or it's been just a fictionalize writing part of the book that Sehmat came into his life when he was merely seven? or by seven he meant seven month not seven year? Also the writer said in an interview after the release of the film that "he didn't see much of mother-son relationship between them, if that's so then is it possible that he was a little upset with the fact that she was responsible for killing his father also for the suicide of his grandfather? Or the reason is something else?

Also why the writer created a mystery about Sehmat n her moms death? at the opening of the book it's written she is dead n in the epilogue of the book it's written her mom died after few years of her death, but in the last month after the film got released the writer is saying she died last month (April) n he is planning to release her photo in June, so does it mean the epilogue contains wrong info n Sehmat's mom is still alive? & does it mean the rest of the info written in the epilogue is also wrong? The book is been republished this year which is revised version as well but still it contains so many confusing info! someone should ask the writer what is wrong n what is right!
