We've got it [Percy's Head Boy badge]," Fred whispered to Harry. "We're improving it."
The badge now read Bighead Boy.

Can't stay long, Mother," he said. "I'm up front, the prefects have got two compartments to themselves-"
"Oh, are you a prefect, Percy?" said one of the twins, with an air of great surprise. "You should have said something, we had no idea."
"Hang on, I think I remember him saying something about it," said the other twin. "Once-"
"Or twice-"
"A minute-"
"All summer-"
"Oh, shut up," said Percy the Prefect.

I was a fool!" Percy roared, so loudly that Lupin nearly dropped his photograph. "I was an idiot, I was a pompous prat, I was a - a -"
"Ministry-loving, family-disowning, power-hungry moron," said Fred.
Percy swallowed.
"Yes, I was!"
"Well, you can't say fairer than that," said Fred, holding out his hand to Percy.

There was a scuffling and a great thump: someone else had clambered out of the tunnel, overbalanced slightly and fallen. He pulled himself up on the nearest chair, looked around through lopsided horn - rimmed glasses and said, 'Am I too late? Has it started? I only just found out, so I - I -'
Percy spluttered into silence. Evidently he had not expected to run into most of his family. There was a long moment of astonishment, broken by Fleur turning to Lupin and saying, in a wildly transparent attempt to break the tension, 'So - 'ow eez leetle Teddy?'
Lupin blinked at her, startled. The silence between the Weasleys seemed to be solidifying, like ice.
'I - oh yes - he's fine!' Lupin said loudly. 'Yes, Tonks is with him - at her mother's.'
Percy and the other Weasleys were still staring at one another, frozen.
'Here, I've got a picture!' Lupin shouted, pulling a photograph from inside his jacket and showing it to Fleur and Harry, who saw a tiny baby with a tuff of bright turquoise hair, waving fat fists at the camera.
'I was a fool!' Percy roared, so loudly that Lupin nearly dropped his photograph 'I was an idiot, I was a pompous prat, I was a - a -'
'Ministry - loving, family - disowning, power - hungry moron,' said Fred.
Percy swallowed.
'Yes I was!

Fred and George turned to each other and said together, 'Wow, we're identical!'

'I dunno though, I think I'm still better looking,' said Fred, examining his reflection in the kettle.

And Percy was shaking his brother, and Ron was kneeling beside them, and Fred's eyes stared without seeing, the ghost of his last laugh still etched upon his face.
