Shoving hair that had come loose from her ponytail out of her face, she looked at George and tried to muster a smile, but she got distracted trying to disarm one of the Death Eaters without his notice. Before she could answer his question, said Death Eater did notice, and turned, his wand pointing straight at Katie. Whatever curse he sent at her wasn't green, but she wasn't waiting to find out what it was, and dived out of the way, scrambling against loose papers that had been strewn over the floor.
Rolling over, she pulled her wand arm up to defend herself, at the same time already feeling the bruises form on the side of her body that she'd fallen onto. She aimed another Expelliarmus at him, but missed, and she pushed herself backwards with her feet to distance herself from him, not wanting to waste the time getting herself into a standing position. She sent a stinging hex at him as she backed up against the wall, aiming for his eyes and hoping she wouldn't miss again.
