When Hruday saw the fear in Saira's eyes he felt something really terrible happened here and now Aanya is so furious for that reason, maybe she would never care if something small but for Aanya, children are her reverse scale if anyone say about her she will not care but if anyone hurts her children then she will not spare them.
That woman saw that many are sympathetic towards her and she wanted to make it big because of this Lady hurting her and also because of her resentment and jealousy towards the Lady(Aanya).
