As they are talking, Vishal becomes distracted, speaking to Hero, and Khanna takes the opportunity to shoot Vishal. Hero takes Vishal's hand and shoots Khanna with the gun. Khanna finally dies, and as Rani is comforting Vishal, he tells her that Hero is with them and he loves Rani. Rani then tells Vishal to tell Hero that she loves Him.
