This is my POV and i might be wrrong .. Do not bash.. it is just a thought ...
After Watching todays episode there is possibility and i m 75% sure that Nupur is dead now.. We did see mayank and nupurs long scene but tomorrow cv will show that mayank is imagining this .. he might be talking to nupur even after her death because he cannot forget her.. and he is angry at samrat because he has lost her.. nupur was the most imporant part of his life.. and not he lost her.. that is why he is angry at samrat and samrat is feeling guilty and blaming herself for her death.after nupur death mayank went to america and wanted to fulfill nupur promise.. as she wanted him to be succuessful .. mayank is fulfilling Nupur;s Dream ..
Gunjan is alive and after nupur death she cannot carry on her relationship with Samrat and may be went to Morena or change her carerr.. and went to meet Neil Oberai and became movie star.. and mayb be after 3 yrs she has become actress or married to Neil Oberai ..may be has got samrat child ..Gunjan may be fulfilling nupurs dreams to become an actress..
