Sandy I look look at that being chakor motherly instincts. A mother senses danger upon her child. I don't think chakor is scared that imli will harm her, she is protective about her child. If chakor was scared of imli, she wouldn't be looking for her the way she did on sat. She was searching for her in the haveli but couldn't find her. If you are scared you will run away not want to know go to the thing/person.
Also yesterday when chakor was running yesterdat and Suraj came she had intuition that something is about to happen, something big.I am in.a way glad they are linking chakor to all this. It shows she has the power to sense what others don't.
