After pocketing her wand and returning to the mirror, Felicity turned to the younger Slytherin and raised an eyebrow. "Why don't you replace it, then?" she couldn't help but ask. There was a bin in the bathroom, along with a supply of extra toilet roll, and it would save another person going through the same thing as the third person in the room. Besides, did she not realise that the Castle was huuuuge and had, like, a million toilets, not to mention dorm rooms, common rooms and classrooms to clean? Food to cook, laundry to do?

Poor House Elves. Sounded like hard to work. It wasn't like the bathroom was flooded, or the toilets blocked.

"You're welcome," she said, offering the younger girl a smile in the mirror.
