He never thought that Irma Pince could turn her back against him and go around him to file the request. During the holidays, he tried to have some control and tell Irma, where she should put certain books, but she didn’t listen. The forbidden section was nearly disbanded, but thankfully some of the books were still critical in Irma’s view, so these books stayed in the forbidden section. After finishing the refiling, she looked closely to the critical books and when she found out that a minority was illegal, Irma removed those books by sending them to the ministry. Other were useful for healing, so she gave it to Severus, so that he could research these potions and spells. And the rest of the critical books were for the DADA class. Irma sent the books to the DADA section, but made sure to mark that the book wasn’t able to be borrowed.
