Most of us have been wondering about this 'act' of the creators of 'HD',and most of us are looking for answers too.So lets just give our version of explanation to this mysterious appearance and disappearance of characters in this drama.As I see it,I think Simi Dewan,Rishi's mother has gone for a long vacation,where she has probably settled down;as for Natasha,she felt its worthless chasing after Ricky,who have become a permanent resident of Chandni-Chowk;whereas Sunaina Bhabhi has actually been exhausted with the melodrama going on in SN,as she was a lively person,so she has gone to a pilgrimage to get peace;and Ishaan:he has also been tired of reminding Zara that She is his aunt Indira,because no two individuals are the same in this world.And Zara not only looks like Indira,but acts like Indira and even feels like his aunt.So,the poor nephew is really frustrated and so he too left for a vacation,to relax his nerves.And the characters whose existence in the show does not make much of a difference,i.e.,Malik Khan,and Shweta,well the magic spell is not really working on them.When they actually need to exit,their stay is becoming longer and longer.And lastly,the characters whose presence have kept the show alive,i.e.,Indira and Rishi,well they too sometimes are on the verge of disappearing.But its the love of the audience that has been compelling the makers of the show to keep them safe from disappearing.
But on a serious note,CVs try to justify the story-line and this act of yours soon,or else "HD" will disappear without a trace.Friends,share your views.
