Greta winced as Z collided with the brooms and unsurprisingly ended up tangled up in a pile with half of them. Greta stepped forward to help her up, but then her eyes narrowed at Z's expression and she put her hands on her hips instead.
"What am I doing here? What are you doing here!" she demanded. "And don't give me that smile, I've seen that smile way too often to fall for it. You always used it when something went horribly wrong and you didn't want to get a detention."
A sudden thought struck Greta and she nearly groaned aloud.
"Please, please tell me you were just trying to steal one of the brooms. If you were booby-trapping them I really, really don't want to spend the rest of my holidays trying to figure out what you did so the first years won't end up traumatized in a really creative way."
