yeah because when ever we have seen something inomshankars family tey have shown nana as part of it but now all of a sudden whenn something soo severe happens he is not there
that day when trisha's condition got serious in the hospital they showed that om shankar was talking on the phone with nana. Nana was sent to bihar to handle some court case as Om ji could not attend himself. He would return as soon as he could.
I think they will soon show nana's return...at least i hope....i mean he has too!! if he doesn't return then how will we see abhi. and if abhi doesn't come how will we see tulika-abhi
