though i am sure that Ragini wont listen anything against Sadhna from anyone but after knowing this she might feel that Sadhna also thinks, because of her colour she might not get a good husband and Sadhna also looks down upon her because of her colour, and i guess it is quite normal for anyone to think like this and on top of this Avni-DB-kaushi are there to ignite the fire
so i for one dont want this truth to be out...Ragini will seriously loose all the confidence that she has in herself after knowing this
