Well chitra as others have already pointed out before me the moles are explained by the fact that the character of DK and Satvik are both played by the same actor Ashish Nayyar. DK is characterised by his limp and the accessories that he used to wear. Now if Guhas decide to resurrect him (am not sure if he is dead. They never showed the face. I can't even say carry out a DNA test as we are not sure if Ved is indeed Dhruv Sehgal's son - thanks to jail scene of Gargi... and am not sure either if they have burned the body that they had got or if it is still lying in some mortuary.) they may just bring him back minus the crutches or with a new face. (like the 'K' serials).
Coming back to Satvik I doubt if he will have any romantic equations with Dish as he is shown to be a happily married man. if Dish thinks him as DK then yes there wud be feelings from her side. But Satvik may be cautious. Now all this if Satvik is indeed a different person and not DK. If after a couple of twists (oops episodes) he turns out to be the real DK then of course it will be a happy ending with a lame excuse for Mrs Satvik and Aaroh (btw Aaroh seems to be a fav name for Film Farm. Even in Dil na jaane kyon under 64 panne slot in Zee the son's name was Aaroh.anyone remember the story ???).
Moral of the story: Everything is possible in Telly land (urf Guha Land, Disha land) though as of now the story is disha less.
Am all ready to see all the unexepected twists. Have stopped using my brains trying to understand these twists. As of now taking each episode as it comes. Now if u r wondering why this long post then only justification that I provide is that while am not watching TD but come to TD@IF I tend to use my brains w.r.t TD. what to do ???
and before I sign off thanks for patiently reading this long rambling of mine.
