1) Navin didn't shoot himself bcoz it was shown in the first episode itself that someone shoots him from back and then he turns and says "tu??" and falls!!
2) if this was the story then Raj had no reason to hide it from Naina. Even if we think that he was waiting to see whether he can believe her or not, but the guilt showed off everytime she talked about naveen!! and this can't be a normal guilt!!
3)yesterday when Rajveer was telling her that Navin took his piston and shot himself, he was nodding his head as though repenting his words and was forcing himself to state them!!
Rajveer's emotions are not fake, they are very much real, but his tears is less of dard and more of Guilt!! bcoz of which he couldn't stop himself from taking a support from Naina😭😭
What say?? Do reply!!
