After more than halfway of the story, while the characters are all dynamic and colorful, but the relationship with Kirill are still shallow and Doug's personal motivation is explored too deeply in one episode that there's no time for emotional investment for his goal. Because of that, there's little to no deductive scene as everything is done in montage and interview. As a mystery crime fan, it's an absolute disappointment. But this episode does have the best plot twist so far. Mid set-up but great pay off.
