Another well-done chapter.
Unlike @drown I'm not onboard with Jamie divulging specific information regarding his job. I still think he should come clean about his abilities instead and tell Mike his assignment is related to that, but for security purposes and Mike's own safety leave out any more details. Ignorance may be bliss, but knowledge is power.
I know Mike was being polite, but there comes a time when you need to grow a pair and just tell people to gtfo. Subtle hints? Ain't got time for that. Even though I'm sure Nam and Melanie were just caught up in the moment and were unaware of the time, the minute she noticed the place was empty is when they should have moved the tête-â-tête elsewhere.
