Harry shifted uncomfortably in his chair.

'You did listen to what I said about a load of it being luck, didn't you?'

'Yes, Harry,' said Hermione gently, 'but all the same, there's no point pretending that you're not good at Defence Against the Dark Arts, because you are. You were the only person last year who could throw off the Imperius Curse completely, you can produce a Patronus, you can do all sorts of stuff that full-grown wizards can't, Viktor always said -'

Ron looked round at her so fast he appeared to crick his neck. Rubbing it, he said, 'Yeah? What did Vicky say?'

'Ho ho,' said Hermione in a bored voice. 'He said Harry knew how to do stuff even he didn't, and he was in the final year at Durmstrang.'

Ron was looking at Hermione suspiciously.

'You're not still in contact with him, are you?'

'So what if I am?' said Hermione coolly, though her face was a little pink. 'I can have a pen-pal if I -'

'He didn't only want to be your pen-pal,' said Ron accusingly.

Hermione shook her head exasperatedly and, ignoring Ron, who was continuing to watch her, said to Harry, 'Well, what do you think? Will you teach us?'

'Who're you writing the novel to, anyway?' Ron asked Hermione, trying to read the bit of parchment now trailing on the floor. Hermione hitched it up out of sight.

'Viktor.'

'Krum?'

'How many other Viktors do we know?'

Ron said nothing, but looked disgruntled. They sat in silence for another twenty minutes, Ron finishing his Transfiguration essay with many snorts of impatience and crossings-out, Hermione writing steadily to the very end of the parchment, rolling it up carefully and sealing it, and Harry staring into the fire, wishing more than anything that Sirius's head would appear there and give him some advice about girls. But the fire merely crackled lower and lower, until the red-hot embers crumbled into ash and, looking around, Harry saw that they were, yet again, the last ones in the common room.

'Well, night,' said Hermione, yawning widely as she set olf up the girls' staircase.

'What does she see in Krum?' Ron demanded, as he and Harry climbed the boys' stairs.

'Well,' said Harry, considering the matter, 'I's'pose he's older, isn't he… and he's an international Quidditch player…'

'Yeah, but apart from that,' said Ron, sounding aggravated. 'I mean, he's a grouchy git, isn't he?'

'Bit grouchy, yeah,' said Harry, whose thoughts were still on Cho.
