Captain Rajveer is absolutely lying...............i saw the first episode n know that Naveen killed by someone he did not shot himself either.......n that someone is none other than Rajveer.....jab naina ko ye pata chalega n she will against Rajveer but tab tak Rajveer usse pyar kar raha hoga..............n he donot want to lose Naina
May be second thought is that ke Rajveer ne apni service n Badnami se bachane ke liye Naveen ko mara hoga, waise bhi Naveen ko Army mar hi deti n Rajveer pe dost ki madat and bhagane dene ki koshish ka aarop lagati to usse accha ke who khudhi naveen ko mar ke apni jaan bachaye n phir sajiz ko pata lagaye ye socha hoga usne.
or maybe Bhargave ne usse order diya Naveen ko marane ka
IN SHORT, Captain Naveen singh Aluwalia ko Raj ne mara
