Paro thinks from her heart and Rudra thinks from his mind. Therefore Paro is always right. Mind is like a slave, you can master upon it and control it, but if you let your mind control you it may turn out to be destructive. That is the reason why Rudra is unable to forego his past and is not rational. Besides Paro nobody can read him.
Due to some frustrated souls I show some niggardly praise for Rudra's character. But I have to admit that Rudra's reactions have drastically change. He was very sweet and obedient towards his mom but when she left him he adopted other tactical ways and formed a hard shell we see today. To make Paro survive he used 'hate method' and to make Paro stick with him he used another weapon i.e making her feel guilty. And now he knows where Paro stands in his life. In yesterday's episode he shows how much respect he has for Paro, first by obeying her and second without interfering, interrupting or questioning her actions.
P.S This is my random thought and I really learnt a lot from your post. Thanks
