The girl has been harrassing savi since the start, she has done things which are't less than a crime and today too she was about to call Savi the S word. So slapping her wasn't wrong IMO. Yeah her interfering in Ishan's personal life and giving him gyaan wasn't liked by me as well. But she realised and later apologised when Ishan strictly asked her not to so. And this making Shukla's Amma doing the ritual is a stupid move by her. College Bhosles ka hai toh unka family member karega na ya college ka koi staff so yeah I agree this was a random step taken by Savi in the name of women empowerment.Makers did this just to create animosity against in Akka Sahib's heart.
