A smile spread across Draco's face as when he looked at Harry. They were waiting outside potions - Slughorn had yet to arrive. Harry looked up, and was startled to see that Malfoy was grinningat him. Actually grinning! Was he plotting some way to murder him horrendously in his bed?
He tentatively offered the blond a smile back, and Malfoy's smirk grew somewhat more pronounced. Was Malfoy smiling athim? Surer now that this was what was happening, Harry offered him a larger, more genuine smile in return.
"Potter, your fly's undone."
Harry never smiled at the git again.
