The monologue was delivered with so much venom and conviction that I wonder what I would have done if I was in Paro's shoes (probably fainted).
I think the reason behind Rudra's anger is not his frustration with Paro's defiance but the fact that Paro has seen his vulnerable side and that he is losing control over his own emotions (growing soft) when it comes to Paro's well being.
Ufff...hot!
