Zoe was certainly relieved that she had cast that warming charm earlier. She hadn't been hit yet, only out of pure luck, but knew that once her cloak started to get wet with snow it might get too cold to handle.

Just as she was zigging left and right, in order to be a less appetizing target, she felt something hit her leg. Whipping around with a determined look on her face, she saw a girl in Slytherin robes and dark hair and she knew from the look on her face that it must have come from her. Instead of coming straight on Zoe turned around again and sped off in the opposite direction, hoping that this would make the girl think that Zoe wasn't going to retaliate.

Making a wide quick loop she came close up behind the Slytherin and let loose one of her snowballs. Thinking to herself, 'Well if I get this close to everyone I try to hit, I should hit someone eventually.'
