The children did as they were told and went to brush their teeth in the bathroom. The edge had been taken off their fear making them visibly more relaxed. So much so, in fact, that some of them mimicked Pythagoras' way of speaking. They cited 'Breakfast, Lessons, Dinner, Lessons …', giggling to accompany their comical exaggerations of the rapid voice and the quaver – although they did it quietly in case they were overheard. Muko wasn't involved because he was still racking his brains as to where he'd heard the name Pythagoras before. In any case all the laughter died suddenly when once again noises became audible behind the door to the classroom.
