Kylie reacted immediately, this is one she'd worked on with her grandmother--she wasn't sure if it would work in this scenario, but that thought hadn't come to her until after she'd jumped about a foot over to the left and screamed "Protego!". Her Shield Charm was still relatively weak.. but if it was effective and if the spell actually hit her it would probably be effective. She felt the spell graze the outtermost edge of her shield, and inhaled deeply. That was close.. closer than I'd rather have anything else come again. She thought. She paused for a moment, so far she seemed to know more spells than most first years did.. and a few second year spells.. although many of them were weak, she could perform them. This girl appeared to be a first or second year, no older. So, maybe with some of the spells she knew she could perform well she could still win. She then quickly snapped up saying, "Expelliarumus!" She'd said, with strength, though towards the end her breath was betraying her.

She readied herself for another offensive attack, in one quick breath she said, "You aren't so bad yourself." She was already getting worn down and all she'd done is cast a few spells and jump about a foot. Maybe the quick thinking was causing her fatigue?
