Why blame Saloni now?

I remember when Saloni saw Dheer with Jhooma in the cupboard she had indirectly asked Aditi if she knew about Dheer. Aditi had told Saloni that she did know but kept quiet because if her brothers knew about it they will kill Dheer. Then why is not Aditi telling others that Saloni did tell her and it is no fault of Saloni.
