In a corner of the Gryffindor common room, the Weasley twins sat huddled together over several pieces of parchment, quills in hand. They kept writing over each other, somehow not so much as knocking elbows in the process. Lee Jordan, from where he was sitting several tables away playing Exploding Snap with Angelina Johnson and Alicia Spinnet, kept casting them faintly concerned looks. If Percy had known what his brothers were doing, he would have shouted at them until their ears shriveled away to nothingness; but one of the things that they had learned from the Marauders and their inimitable Map was how to make things on parchment look entirely different from what they were. To Percy, it just looked like they were finally doing their homework; and so he left them alone.
