exactly i agree on the ritu part completely.even if ritu was negative whatever she did was for her country.atleast she was loyal to her mission and her people.till her last breath she fought for her mission.she didnt have any personal grudge against raj.but as far as naina goes.ok i agree she is also here for her mission of finding truth abt her bro.then how can she be so inhuman towards raj who helped her majority of times in her mission.she is behavind as if he did a cold-blooded murder.i mean cmon it was mercy killing yaar.naina's bro only begged raj to kill him as he didnt wanted to be killed by any other person.i think it was good.atlest he died by his frnd's hands.it was better than being killed by ritu or any other army officer.i think naina shld get her brains bac soon.though she has already made the mistake which i think is much bigger than rajveer's mistake of hiding the truth.he hid it becoz he knew naina would never understand him and he was right.
