She always keeps telling mera papa kehte hai ki ... ---> Where did her papas words and ideals go? Gone with the wind? Did her papa tell her that keeping the family in a state of false notions is the best thing to do even if it means sacrificing a life? If like @Lachu always said for her Thapki and Bihaan are one - so she doesn't mind him dying? I am sorry - if this is love, I don't buy that kind of love. I don't need that kind of love nor will I promote such kind of love!
Even I believe in the Sanskrit Subhashini - satyam bruyaat priyam bruyaath na bruyaath satyamapriya,.
But this is not about not "uttering unfavourable truth" but it is about "uttering lies". Thapki has been lying to Bihaan.
If this is FL glorification track, then I don't believe they are achieving it. They have butchered her character sufficiently. I am wondering whether this track is for butchering Thapki's character or to make a Saopla out of DS or like some people / spoilers say this is Bihaan ke pyaar ki parikshaa?! I can't believe. It is all about how low Thapki can fall to keep her ex-es true secret from everyone. She can even go to the extent of killing her husband (indirectly of course - supporting or keeping quiet when a person commits a crime is equivalent to committing the crime).
