Paro is scared of fire, She is scared of BSD and her Maami gives her a rudrakshmala to protect herself.. Who is that Rudraksh in reality? It is none other than Rudra, who is himself a BSD officer. How beautifully they have linked the other fear of Paro, the fire with the fear of BSD?
Like fire is destructive, it has its good uses too. Her Maami uses Paro's fear for fire itself to explain that it is not so bad. Infact it is good. Similarly, Paro will get to know through a BSD officer himself that BSD is not so bad and infact they have a heart too. Beautiful treatment of the concept.
Second, the mystery that surrounds the wedding ceremony itself.
Who is this Takur? Is he someone who helps and terrorists and people trust him to protect them from BSD? Is he someone who plays between BSD and people and manipulates both the parties for his benefits?
Interstingly, one of his manipulations is going to bring Paro and Rudra closer. Waiting for paro's wedding, for this will make her fall in love with her husband's killer
