Potions class was, as always, another class Kat was looking forward to. Maybe the only class she was most knowledgeable in, from all the reading she had and her interest in it as well. She had all her things (for all her classes today) inside her bag with the undetectable extension charm they learnt last term in Charms, when Professor Bellaire was not yet the Transfiguration professor. It had been quite useful since this term, they were required to pay whenever they enter the common room AND the great hall.

Kat entered the classroom, and saw that Professor Lafay was sitting on her desk with her legs crossed. Nothing really interesting inside, like a baby girl from last term. "Hello Professor," the prefect greeted and went to take a seat. So... what're they gonna learn today?
