I meannnn

We all know they meet again but I was still picking my jaw up of of the floor. I have a very good feeling that Hyo-Un will go absolutely ape shit and kill each and every guard including the brother/weirdo in turn using all of his power meant for completing the orb along with his strength which will cause him to fall into a sleep where he of course loses his memory. It's a pretty good guess but At the end of the day it's just a guess which is why this won't be tagged as a spoiler.
