Given the SBS info on the "war", the violence, it seems this will be Dutta's Kurukshetra. The place he will face Anna to the end.
It is here I hope that Anna teases Dutta about Naku's involvement in the Sups affair, that there was no involvement. She did nothing. What a bad judge of character Dutta was (reinforcing what Jagpat had said also).
Also, could our Naku be the one who kills Anna? She is Dutta's protector, after all.
