OK, I saw this on Zee news House arrest. Sin was cutting a cake on which 'we miss you' was written. There were not many people on the set except aniket, chandra, aditi, director and few technicians. Everyone said their last words as though Sin was really dead. Then Sin took mike and started 'aapki apni Sindoora' but she was laughing a bit while saying this(she might have read posts on IF😉).
She was wearing another saree and was perfect with full make up and her attire and her trademark scar on forehead.
I guess it is good bye to Kamya for ever from Dulhann. They were shooting some sequence it seemed. She was sitting in her chair looking at the ceiling.
May be we could see a scene (of her) after her death in which she might say aap ki pyar(ya nafrat) ke liye shukriya and blah blah blah(or probably they are shooting that for a promo).
