text: 1. As the name itself suggests "Heart of the Ocean" Old Rose thinks better let the blue diamond rests where it truly belongs.... with the memory of Jack.\n2. Obviouly Rose's.....since it was she who was telling the happening in the car.\n3. Yes.....Remember it was Rose only who was still survived and those who were there in the final scene, were her real admirer. Many critics (including those in the inner circle of director James Cameron) think it was not a dream....but 100+ years old Rose dies in that very night when she drops the diamond in sea. Try to visualize that shot before hers ascending the steps....she is shown on cot....in deep sleep....actually dead....then her soul goes towards Jack's where it rests eternally.
