Janus tutted about the state of her wand, when he saw it. "That monitoring charm that’s on your shop-bought wand is now on your personally crafted one as well! It must have been cast after your arrival at Hogwarts. I’m quite confident the wards around Hogwarts won’t allow monitoring to work properly while you’re here, but as soon as you leave the grounds there might be trouble. I’ll remove the charm for you, but I’ll leave it in place on your artisan-made wand so they have something to track. No need to alert your enemies that you have an ally who knows how to remove tracking and monitoring enchantments." Hermione felt extremely relieved that she’d managed to avoid getting in trouble – no-one ever asked about what odd spells she (or any other Slytherins) had been casting. It seemed reasonable to her that even if Hogwarts’ wards didn’t block information about the spells she cast reaching the Ministry, surely no-one in the Ministry would want to have to deal with the paperwork that would come from scrutinizing the spells cast every day by a whole school full of wizards and witches.
