On Christmas day, Percy ambled downstairs with a faint look of pleased bemusement on his face. He was wearing his Weasley sweater, which was helpfully labeled P for prefect (Ron snorted), nibbling absently on a piece of fudge that probably had come with it, and staring at a piece of parchment. The twins, who had been throwing tree ornaments at each other, paused, looking curious. "What's up, Perce?" they chorused. Ron looked up from feeding cockroach clusters to Scabbers as Percy laughed. It sounded oddly genuine, deeper and warmer than Percy's usual uncomfortable, nervous snicker.
