I guess he's something like a traitor, and he's manipulated by that chick. When he pours his blood in the glass it looks like he's in that old room that also appeared in Given-Taken. And during the party scenes he's the only one spacing out, seems like he's scheming or forced to sober up the rest. It seems like they left that old world and entered a lotus eaters-like trance in the new one while partying, and Sunoo is obligated to bring them back?
Ooooh. That’s sounds cool. 👀
