I stand off to the side and watch as she talks animatedly to them. Weasel says something to upset her and she stalks out of the hall. I follow. I find her by the front entrance of the school, she looks cold so I cast a Warming Charm around her as I approach. She doesn't know it's me because she says, "Thanks, Harry." I can't help but chuckle causing her to jump in surprise. "Malfoy? Er, um, thanks." I smile at her and she begins to blush.
