An ending in the best way possible. :) And with promise of a sequel.. maybe? I would like to see more mysteries starring this particular duo, but if this is where it truly ends then that's alright too, couldn't think of a better way! Conclusive, charming, and with a little leftover confusion to keep the viewer intrigued even when it's all done. The hand was a nice twist too. XD Wasn't expecting that! But it's suitable.
It really has been getting better and better all season, from the point where I was a little curious over what would happen next to where I'm exhilarated to see the new episode appear; watch it promptly. Right now there's really no other series here on NG with such an effect, so it must be doing a lot of things right. Script-wise, mainly. Everything is great, but the brooding mood and atmospheric build-up is the best part. And the carefully contrived and so colorfully clashing characters, of course, just wouldn't be the same without them!
Great work on this season, and hoping for more if there is more on route! Hint seems to hint like... there might be. It's been a pleasure to follow.
