I am stuck at this scene when Prerna stands next to RB and he is facing his back towards the audience. there is a very subtle pause. eri's body language I liked.
it's like, P is powerless currently, but RB doesn't like to see her this way. he understands her hatred and helplessness and gives her that moment to pull herself up before facing him to say that she is ready for the marriage.
And yes, it was good to know P has started to slowly understand this man. the way she starts about "ek aur shart" and then corrects herself immediately after RB's reaction, saying "ek....ek request". She has finally given up. It was a mix of despair for her past and adjustment towards her future.
she now knows there is nothing that will back off this man and change his mind and he will do exactly what he says irrespective of any conditions attached or added. this might appeal to her unknowingly as her previous relationship did not always hold true on this factor.
