To be honest I am not at al worried about this. Hina is here to plain the negative character. That's what she herself has said from day 1. But she is a celebrity and she will get screen time. We need to be prepared for this. Maybe even more than Naveen but it will all be negative like Naveen.
My main issue with the precap was not fear that suddenly Komolika is going to be the new love interest. It is similar to the concern many people had during true Naveen track. It's about the writers messing with the characterisation of the leads. During the Naveen track, it was prerna. And now it's anurag. Each new addition is weakening anurag and I don't like that.
First all be bitching by Mohini and Nivi while he is silent, then the mishka confusion and now him under a lap dupatta with Komolika. I think the writers need to tread very carefully with anurag or else that halo will get completely tarnished.
