Oliver knew it was a bit hard for the straight-laced Percy to get over this. He would, of course, if he intended to remain friends with Oliver, but it wasn't going to be today or even tomorrow. All he had to do was show his friend that nothing changes, that he's the same Oliver as before. "Being friends with someone who is gay is expanding your horizons?" he said with an amused look. "You're not getting out of coming to the Quidditch pitch with me so don't let it cross your mind."
Mentioning he was seeing someone than the pitch so soon left a sinking guilt in his stomach. He wanted to show Sam the Quidditch pitch, what he did for a living for real and why he had the scars and bruises on his back. From hard work doing something he loved, and not just any sport, but Quidditch.
