Since Racheline didn't seem capable of more then just standing there watching, Sally took a second to cast a shield charm around the girl, knowing John wouldn't think of putting a tracking spell on them.
As she watched the snowballs, she realized that he probably hadn't peed on the snow. Sally felt guilty about hitting him with the ice balls before ducking to avoid the snowballs. She stood back up when she thought they were all gone except to get hit by a green one a second later.
Sally scowled and made a snowball and charmed it a rainbow color (which would spread to cover the entire body once it hit) and put a tracking spell on it. Then she smirked as she watched the ball chase John.
