Karkaroff glowered at the universe in general as Bagman gave Potter a ten. The wretched boy deserved a zero. He'd used a broomstick, for Merlin's sake – flown around the Horntail like the task was a Quidditch match. The point of the tournament was to test the champions' magical prowess, not their athletic ability...and if it came to that, Viktor could have flown circles around his dragon. Severus was right; Potter was clearly a damned little showoff.
Unfortunately, Karkaroff reasoned, it would be impolite to give Potter no marks whatever. Sourly, he raised his wand and conceded to a four.
