Être intelligent, qu'est-ce que ça veut dire?

Mrs. Kelleur's tooth from the previous episode is transformed into a stone tooth. Sam and Alice try to discover the meaning of this transformation. Meanwhile, Gael asks Sam to help him with his math so he can pass his exam. The help requested is to cheat and Sam is really not comfortable with this request. With the help of a special neon, Alice discovers in a special book the explanation about the stone tooth but can't verbalize it. Reading to learn is at the heart of this show!
