Alani noticed that the castle seemed to be undergoing an extra-thorough cleaning. Several grimy portraits had been scrubbed, much to the displeasure of their subjects, who sat huddled in their frames muttering darkly and wincing as they felt their raw pink faces. The suits of armour were suddenly gleaming and moving without squeaking, and Argus Filch, the caretaker, was behaving so ferociously to any Student who forgot to wipe their shoes that he terrified a pair of first-year girls into hysterics. Alani was being sent around the school, she was helping Filch fix broken things. She had to do it, because Dumbledore made her do it.
