Question: What does Jack whisper to Nina? When Nina hears this she is horrified.
Answer:I watched this with subtitles on, all you hear is him say 'now...' and continue to whisper, you don't hear what he says but you know it was bad enough to frighten Nina.
Answer: As she said to Jack she wasn't working for the Drazens, she was working for some Germans as well as they were telling her to go to Berlin.
