People could be very contradictory sometimes. Although they sincerely wanted their good friends to do well, if those friends did too well, they would feel just a little jealous.
Before Ron took the field, for instance, Harry had sincerely hoped that he would get a good score, and had even prayed that Ron would face a dragon that was easy to handle.
But when Ron really did fly back and forth past the Portuguese Long-Snout with dazzling flying skills that could only be called outrageous, running circles around it and winning cheers from the entire crowd, Harry felt a little jealous again.
He tried his hardest to despise himself for it and tell himself that it was wrong to think that way. Yet he still could not stop those feelings of envy and jealousy from rising.
"Heavens, Merlin above, did everyone see that? Our third-youngest champion is putting on an unbelievably extravagant performance. Right now, he's like a swallow up there, a peregrine falcon-one of those birds that are the very best at flying, in any case. He's so nimble. Look, he's dodged the dragon's breath by a hair yet again. Spectacular, lethally spectacular!"
Bagman shouted and exclaimed, without any of the composure an adult ought to have. Still, wizards did seem rather unlikely to develop steady temperaments. Just look at Dumbledore: didn't he go around smiling all day, telling terrible jokes that could freeze the entire Great Hall whenever he had nothing else to do?
Perhaps that was simply how wizards were.
With little pressure in their lives, their temperaments tended to be rather wild.
The stands provided ample proof of that at that moment. Countless spectators from all over the world were shouting and exclaiming too, crying out at Ron's downright terrifying performance.
"Viktor, what do you think?"
