Parth said in one interview when asked who was Komolika that he too wanted to know bcos he had to get married to her.
So let's be clear that from day 1 when they sketched out the story the one detail they had sketched out was that parthh would marry Komolika.
With Indian serials I think they sketch out a basic storyline and they write the script or change according to TRP and fan feedback. I think if anurag doesn't get married to Komolika it will be because we fans have shown them that this is not a story we will accept.
It turns out that we don't care if anurag and prerna remain star crossed lovers but this idea of marriages for the sake of rescuing ones family and all that old fashioned movie bull crap, we don't like it!!!
So let's see what the bif cat few weeks show and whether AltBalaji and starplus listen to fans.
