A scholar assassin. oooh-kay.
It's interesting to see that some order ended up in another dimension - I bet our empress has taken quite a few calls regarding that -, and what they did with that.
The thing is... I truly think Han Jingun is projecting the helplessness and anger he felt that day on Hwangwook. Jin's crappy king and his irresponsible behaviour is the cause of this all (at least that's how I see from what I've gathered) but he's already dead, so there we go, how convenient to blame someone else. I mean yeah, he was the general of the army whose soldiers killed that scholar lady in the end, but it wouldn't have come to that, if it weren't for that crappy king. Is what I think.
