Vista Di, I also loved your post. I agree that Rudra is still affected by the absence of his mother and this is why she is always on his mind. A woman who was too beautiful to settle down with anyone, not with her family and most definitely not with her child. Rudra has lived a loveless life where both parents denied giving him the love that he deserved. One parent ran away while another nurtured him to hate the very gender responsible for his existence and presence on this mere earth. He is still pained by his mother's betrayal and yet he has learned how to hide his pain and vulnerability from the eyes of others. It was interesting to see the reversal of roles where Rudra becomes a dominant person who forces his father to eat and then shouts that his father must forget that treacherous woman who has scarred their lives. Yet, his father states it's impossible to forget her as he sees her in Rudra, they share the same eyes. In the past, a little Rudra has been forcefully told by this same father that he must not sulk or weep for a woman who never belongs to anyone in particular.
Paro has also lived a painful life but she was surrounded by the love of her family which helped her recover and become the sweet and gentle woman that she is. Although she was denied the love of her parents at a young age, she has learned to appreciate love in any form that comes to her and spread love to others as well. She is still devastated by the loss of her parents and her nightmares bare witness to her ultimate fear of dying by fire and in the hands of a BSD officer. She finally realizes that Rudra was her tormentor from her dream but she's probably confused as he was also her savior.
I love how you've connected them with Lord Shiva and Parvati, the father and mother of our universe. Parvati is the other half of Lord Shiva and he is not complete without her. Similarly, Rudra will not be complete without uniting with his soul mate Paro, who will teach him the true meaning of love and life.
