Thog crushes Roy through the floor of the seating area down into the first floor of the arena. From his new vantage point, Roy notices the guards carrying Zz'dtri away and realizes that the gladiatorial duel no longer needs to be prolonged. Roy taunts Thog into smashing Roy's head (ouch) into three successive pillars, at which point Thog's rage wears off—so Roy kicks Thog into a fourth support pillar, collapsing the massive ceiling onto Thog. Knowledge (Architecture and Engineering) FTW.
