So considering these types if we analyse Samar's behaviour he stalks Indira, ties her down, sends her bleaching cream as a gift, applies haldi to himself alone in a dark room keeping her picture in front of himself (which I thought was hilarious 😆) So going by these clues I think he is obsessed with women and beauty and most probably hates physical flaws he might try to change Indira's appearance as well. And as every psycho has an event or something in his past to trigger that behaviour I think for Samar it might be gender complex maybe somewhere deep down he is more feminine than masculine. I know I'm going off tangent but these happens in real and maybe he is forced to not accept his sexuality by his parents which might have led to his psychotic behaviour. I know it sounds really weird and bizarre but it's just what I gathered from what I saw of his behaviour. I don't even know if RS is brave enough to tackle a sensitive subject like that but it's a harsh reality that should be shown and if she does then I'll really appreciate such a track honestly.
