Benedict has the power of petulance on his side in most cases, but the sheer force with which the pillow hits him in return is enough to knock him on his ass with an undignified gasp.

He sits there a moment, blinking in wide-eyed offense, but (perhaps in contrast to how things might have gone years ago), shakes it off in a moment or two, standing to approach with the pillow held in both hands. His expression transitions from confused to diabolically gleeful in the time it takes him to cross the room, and, in a motion rather unlike throwing the pillow, yanks it down over one of Vlast's horns.
