I think if DM-Santo get divorced, it will be very hard for the creatives to show them getting remarried. To begin with, it was very hard for a lot of people to see a marriage of such discrepancy but at the time atleast there was a reason, some sort of justification. What reason would there be for them to get remarried? What reason would DM have to remarry Santo - that he loves her - am not sure how that would make his character look. He has feelings for Santo and cares for her but I don't beleive he is in love with her yet, how is he going to fall in love with her after they are divorced and not living in the same house. If this happens, it would totally ruin DM's character. It was one thing he was forced to marry Santo due to circumstances, totally different thing he marries her voluntarily. So, I hope the divorce does not go through because if it does, I don't know how the creatives are going to get them back together without ruining DM's character.
And what about the tagline of the show - "ek atoot bandhan"? How can they break an "atoot bandhan"?
