It wasn't as hard as he was expecting, once he stopped stressing out about it so much. He just intermittently cut across Hornby's trajectory, causing the Hufflepuff to veer off course in alarm. Practice had paid off (he spent most of the Gryffindor practices rehearsing exactly this maneuver, getting in the way of the Chasers). By an hour into the game, his yellow-robed opponent looked like he was spitting nails, Gryffindor was sixty points in the lead, and Percy was starting to understand why everyone enjoyed this game so much.
