Professor McGonagall and the Bone Spell

Several days after the unfortunate 'Bone Underwear Incident', as the Gryffindor's had dubbed it, Harry and Ron were sulking in the Gryffindor common room. The lazed in the armchairs silently, staring into the blazing fire, their expressions morose. Ginny skipped down the stairs of the girl's dormitories happily, stopping short at the sight of them. She raised an eyebrow.

"Hermione's still not talking to you two?" she asked. The pair shook their heads, their frowns deepening. Ginny looked thoughtful. Hermione never held out this long on talking to her two best friends - what could be keeping her occupied? She shrugged inwardly and skipped out the portrait hole, figuring she would interrogate Hermione later and find out.

Meanwhile, in the Transfiguration classroom, said Gryffindor and her teacher were arguing about the origin of the Bone Spell.

"Professor, do you honestly believe that this spell was not made for dark purposes?" Hermione argued, trying to get her point across about the danger of her best friends and their experimental spellwork. McGonagall shook her head, lips thin.

"Miss Granger, I do believe it is so, and I would not like to hear anymore of your BACK-TALK," she emphasised the last two words as Hermione opened her mouth to protest. With a frown, she backed down and crossed her arms. The glum look stayed on her face as she swept herself from the classroom with a huff, turning in the direction of the library. McGonagall looked after her with an amused quirk to her lips and turned her head to gaze at the bone underwear. Certainly, she was curious about what kind of spell had caused such a reaction, but she did not believe it was meant as dark magic.

She pulled her wand from inside her robe and tapped on the underwear. There was no reaction. She muttered a spell under her breath, and was astonished to see an engraving come up within the bone. She peered closer, her eyes widening as she read the message.
