expressionless looks he gives unsettling.
Pia's memory may have returned and she realizes that
someone is out to kill Bani and she told Jai about the explosion
etc. With Bani in jail (the safe mode), the real killer would be
secure in his success and become reckless and thus JW will be
able to set a trap and catch him.
My only worry is it might become too late as Tarun will abduct
Bani to a foreign land, he can't see his love rotting in jail being
punished for a crime she did not commit. Bani will never come
to know of JW true intentions. Then she will return after 5 years
to take revenge on all who had pronounced her guilty and cast
her aside.
Of course, my alternative story would be the real JW has been
kidnapped I think at the airport, (that is why no hugs between
JB and they seemed distant since then, ) this is the nakli JW
(Saahil undergone major plastic surgery) and he is taking
revenge on Bani by sending her to jail or mental asylum (if she
isn't mad yet , she will be living with the pagals). As JW he
rules over WGI and WM.
