And no I wasn't expecting Kastur to be supergirl or something, but she should've done something at least.
If that was my fiance getting beaten up, I would run to him, and be in front of him, trying to protect him the best I could. Ok, I probably wouldn't be very good at it, but I would try at least.. If you love someone as much as Kastur believes she loves Mohan then you would do anything to protect that person😊..
