Of course, the obvious answer is the assistant, Miji. I don’t know though, i’m not convinced. I thought it might be the mistress, Hanna, but from photos, it looks like she’s left the country in the last ten years, so she’s out. My dark horse pick is Junik’s mother. She has the political savvy to start a war. She also has the means to build a submarine, good enough to fool the American military. Junik caught his mother embezzling funds, maybe she used that money to pay for the submarine. That would imply that Junik’s own mother had him assassinated, but if she‘s a loyal spy, maybe she thought her son was a noble sacrifice. Does anyone else have other guesses?
