Nice post,and a good point for discussion.As far as I'm concerned,I believe Rishi's prayers will be answered,though it is quite uncertain how?,but either a miracle will happen,or everything that is happening is in Indira's subconscious,in the state of coma.Well this is my assumption,because this makes more sense:the show,which has been accepted by the audience so well,and which has not even completed a year,couldn't possibly end in a tragic way.And if the writer and CVs of "HD" are having this thought of plotting the death of the protagonist itself,than it will be a blunder,because,lets assume that Indira will die,and some look-alike will replace her,or any such weird ideas;it can never bring back the essence of the show.
Besides I have reasons to believe that nothing tragic is going to happen,because if we go back to those moments in the story,where Rishi very often uttered the word 'death' in most of the episodes;his kidnapping track,which soon followed:but in the end,nothing tragic happened,as assumed by the audience.Similarly,I believe it is just a technique used by the writer to raise suspense in the story,making the audience sit on the edges of their seat.And after all these hue-n-cry,nothing tragic is in the cards.Both Indira and Rishi,the characters,as well as Rati and Sumit as actors,are the soul of "HD";and with the end of either one of these characters,it will be like a nail in the coffin.
