Will is gone for the day, being needed in the infirmary. Normal things—or so he thinks. But someone, wanting revenge on Nico and being jealous of his power, takes him and traps him in a room that’s designed to take his shadows from him. They want to take them from him completely so they won’t be weak anymore. And they succeed—leaving Nico weak and entirely drained, just praying Will finds him before it kills him—because now it’s just pulling at him, the essence of his very life, since his powers are completely gone.
