It was one of the last days of her break when she was working on a technique to make a stronger sleeping draught potion using fewer ingredients, but so far, it wasn’t working out very well. She had already tried to make it five times but all she got was a purple mess. Crookshanks was also somewhat nervous that day, meowing at her, begging for attention, following when she went to the dungeons, and scratching the door when she closed them before the cat’s nose. Annoyed with the mewls and the scratching Hermione decided to let him in and Crookshanks spent the whole day with her in the lab, getting purple dye on his fur when he threw one of the experimental vials to the ground.
