[wkeej]

Hello, anyone watch Golden Slumber? I have some questions with regard to delivery man Aoyagi meeting his old friend Morita.
1. What is the latter's employment?
2. Does Morita know about the assassination plot?
3. Is Aoyagi supposed to die?
4. Did Morita deliberately save Aoyagi?
5. Is it planned that Morita need to die? If so, why?

Thanks much.
