Gretel looks back at Doc and the spark stayed in her eyes. "M..Math..." She tried to say something again. "M... M..Math..." Some tears seem to form in her eyes. "Herr... Doktor.... what is going on?" Hilda said. "I tried singing to her... but... she didn't react to it..." Hilda kept watching as the Nanny left the room again. "Why... didn't it work... when I tried it?" Hilda sighed. "M...Math..." Gretel said again crying and the spark was truly in her eyes.
