Overall, it's an interesting movie. Fast-spaced. I have two questions towards the end of the movie. When the "bad" N Korean guy Dong played the tape, initially it is about the "good" N Korean guy Pyo willing to claim liability for his mistake. Thereafter, it went to some conversation.
1. Can someone explain the conversation?
2. How is it possible for the conversation to appear after the Pyo's voice?

Thanks much.
