My prediction is that the scene of the dead body being brought home is only for the promo. In the actual episode, I think they will say Samar died trying to save Anuj from the goons but during the scuffle his body would have rolled off a convenient cliff (that somehow appeared near the miraculous pub in dry Gujrat). So it won't be recovered.
Everyone will think Samar has passed away. But of course he would have rolled down the cliff, fallen into a river and be washed away to a neighbouring village. There he'll miraculously wake up near a Krishna temple on the river bank (thanks to Anupamaa's prayers).
Of course, head injury. Of course, memory loss.
He'll meet some eligible sanskari lady there (daughter of the pujari?) and get married again only to resurface in the main plot as a dramatic twist the next time the TRP drops and needs resuscitation.
What do you think?
