Just want to add a few points to Vidya's wonderful update: they show us in a flashback Disha telling DK before she dies that she wants him to marry again and have children and spread his love. Cut back to the present DK is in front of Disha's huge photo and telling her that i have done what you wanted and distributed my love between my 3 children but even after all these years I'm still your Dushyant...looks like he hasn't been able to make place for Kaamna in his heart...the kids are his and Kaamna's
