Rather than responding to Grantaire's comment, Lan Wangji returns the entirety of his attention to the game. He catches the ball on a flipper, bounces it at a precise angle such that it returns, and then rockets it directly into the final locking position. There is only the very slightest look of surprise on his face, a minute widening of his eyes, as the multiball begins, largely because there is no time to be surprised when he must contend with the consequences of what he has wrought.
