Exactly. Remember in the earlier episodes she was very warm towards Ishqi and was so impressed with her. It all went south after Daadi saw her taking care of Savitri. It makes sense to me if she wants Ishqi out of their lives for this reason only but turning her completely negative seems a bit too much.
Yeah ... that’s why I believe Dadi is only looking out for herself - she can throw any of her kin in fire to protect herself. Look at the way she has indoctrinated Ahaan against his mother and all women who use their brain
