U all know that Abhi is in search of Navins murderer and wants to punish him.
Well Naina knows that it was only Rajveer who shot Navin.But she wont say it to Navin as she wont like a 3rd person to trouble her Rajveer sir.But she 'll keep taunting him and hiding her feelings for him., maybe even siding Abhi to find out the entire truth..
But at the time Rajveer leaves KMA, she's gonna cry a lot and even make him cry. Both will forgive each other( Raj for killing Navin and Naina for shooting Rajveer).but they may not unite bcoz acc. to rules of KMA, acadet cant get married during the training period. Finally in the end of the serial , Raj may come and take his LIEUTINENT OR CAPTAIN NAINA with him in HIS ARMS.
Hope something like this happens!!!!!!
