Percy just shot Oliver a Look over his glasses, but he couldn't bite back the almost-smile crossing his face. "Don't be surprised if I get annoyed with the Quidditch players for blocking the art, in that case," he retorted. "After all, it's for looking at, not flying about on."
At Oliver's request, he nodded, checking the map again. "We'll go over some of the more famous British artists, then," he replied, "like Gainsborough's show boxes, and there's a good selection of Italian art in the next room over. Come on." He gestured with his head and began to walk, clearly expecting Oliver to follow.
