He's on alert immediately, weight shifting to the balls of his feet and steps becoming very carefully placed. Something has gone Very, Very Wrong, and the cool stillness in the air certainly isn't doing anything to settle his nerves. His breathing automatically slows, becoming utterly silent as he casts his eyes about the room and strains his ears to listen for any sound. As far as he can tell the walls are walls, the table is a table, the liquid (water? Poison? Acid?) is liquid. The only thing not immediately visible is whatever's behind that judge's bench, so naturally that's the first place Yakumo heads; skirting around the table, taking great care to avoid touching anything lest he spring a trap, shoes not making a single sound against the floor. Behind the desk might be an enemy, might be a trap, might be nothing -- but whatever the case, he won't find out by just staying still and waiting.
