LATEST PROMO- clue found inside d tape

the promo was aired so suddenly on sony dat i could not follow d whole of it but whtever i saw was like dis.......... naina & abhi r searching 4 alekh. d landscape was something different and i couldn't clearly understand whre it is, anyways it seemed a rocky place with a sort of broken fort kind of thing. alekh & raj r hiding on d top of a big rock. d tape recorder of naveen is in alekh's hand. alekh says "is tape me zaroor kuch baat hai" . just den raj tries 2 take d recorder frm him and it falls down and breaks. naina cries and says "is tape me bhaiya ki awaz thi". abhi tries 2 console her by hugging her. raj takes d broken tape saying" shayad naveen v yehi chahta tha". inside d broken tape he gets a piece of paper. i guess naveen kept some clue in it about d red box.
