Every single book is robotic, so they all move, they all make sound, and when you put them all together, they turn into these walls, which have the gesture and the personality of Simon Powers. So he's disappeared, but the whole physical environment becomes this person.
Tous les livres sont motorisés, bougent et produisent du son, et quand on les met tous ensemble on obtient ces murs qui ont les mouvements et la personnalité de Simon Powers. Il a disparu mais tout l'environnement physique l'incarne.
