Hey disha
As per the synopsis of tumarhi disha by zee tv Dk is divorcee! so these people might show the entry of his first wife(gargi might bring her) at the time when dk and disha are very much in love with each other who might bring about misunderstandings in their minds so that they will land up in a divorce.
After divorce ,they might show Disha being pregnant ,Dk might ask her to marry him which will be supported by dk's mom sumitra . Dk might tell disha that he does not want to create another DK who is deprived of father love and name , Disha might realise that she cannot stay away from dk because she loves him a lot.
But i hope thet they don't take the story forward as they did it in Astitva, were simran and abhi stayed away.
Jingle, I have the same thoughts as you.
