Although the series is great and mind staggering... It has suspense in its every episode at the end... But many parts of the series are left unrevealed... Like it doesnt showed how the Anjali Mathur's father was related to RAW Yadav Taayi... As in the beginning when sartaj got Anjali diary after her death and he went to Yadav Taayi home and asked her how she knew about Anjali's Father ... And the secret behind Yadav Taayi's daughter interrupting the conversation by saying that he was her mothers collegue... And Also it doesnt showed how Taayi became so weak and depressed patient ???... Also in season 2 they showed that Shahid Khan who was the terrorist was talking on phone with his mother and at the same time they showed that his mother photograph was in Sartaj's mother photo album who was seating in her veranda and watching those photographs... It means there was some connection between sartaj singh and terrorist... BUT THEY DOESNT SHOWED THIS !!!! Beside it there were many secrets that are not opened till the end... At last good work and if anyone knows secret behind this parts please tell...
