And who knows maybe Kamal is acting to make parvati crazy and he probably told some other story to Trishna. and now Trishna might laugh with Kamal that they are both together to ruin Parvati.
i don't know where Ekta is taking us. She very well know that the main char can not die so why bother showing like this. oh maybe Trishna might hospitalize and Kamal might blame everything on Paravati that she did all these because Trishna wouldn't listen to her.
