I think the person under doubt is only Tanya..she must be alright and must be doing blindness drama..
she is the one who is odd now..and gues what would be the news..that manthan is nandni's son.. if everyone remember then..when nandni was in jail she was shown as pregnant and mandira asking for her child.. nandni out of fear could have given away her next child manthan too to tanya..which would be shown as suspense in the next episode..
and i believe this would be 100% next story. 😊
