PERCY WEASLEY AND THE GOBLET OF LOVE
"Percy's enjoying work, then?" said Harry, sitting down on one of the beds and watching the Chudley Cannons zooming in and out of the posters on the ceiling.
"Enjoying it?" said Ron darkly. "I don't reckon he'd come home if Dad didn't make him. He's obsessed. Just don't get him onto the subject of his boss.
And they did that evening, or rather Percy did at dinner. He tapped his cup with a fork. "Ahem. I am pleased to announce that Mr. Crouch and I are to be married next summer!"
Every single person at the table had a different look on his or her face. Mr. Weasley had a weird smile of disbelief on his face. Mrs. Weasley looked like she just got hit in the stomach by a bludger. Bill's face was twisted with utter confusion. Charlie seemed to be contemplating the news. Ginny's jaw was almost touching the table. Fred and George kept trading expressions of disgust and acceptance. Ron was on the verge of tears because he was trying so hard to contain his laughter. Hermione had a look on her face that screamed, "Surprise surprise." Harry just looked at all the Weasley's expressions without a reaction of his own.
They all sat there for the longest time until Percy broke the silence. "Well? Isn't anyone going to congratulate us?" He was grinning at everyone around the table. They all suddenly burst out at once with "That's great!" and "Couldn't be happier." Percy was beaming with pride.
Unfortunately Crouch was killed by his son a few months later.
