His mask didn't just slip, it essentially evaporated.
Which I'm very glad despite having liked the character previously. I still do from a narrative standpoint I suppose.
He can't be the little roleplayer who thinks he can fool the world anymore, we know what he wants to do, we have his "pawns" on our side, and to top it all off we've likely messed with his connection to the shadow realm, his biggest crutch.
Well. It was. Looks like Seren can't burn him after all.
