'I'm not staying behind!' said Hermione furiously.
Once more, the wall span and became still again. Harry approached another door at random and pushed. It did not move.
'I can hear them too,' breathed Luna, joining them around the side of the archway and gazing at the swaying veil. 'There are people in there!'
'Well, we'll have to fly, won't we?' said Luna, in the closest thing to a matter-of-fact voice Harry had ever heard her use.
'Sirius,' Harry repeated, still gazing, mesmerised, at the continuously swaying veil. 'Yeah . . .'
'Keep going!' said Harry sharply, because Ginny showed signs of wanting to stop and watch the egg's progress back into a bird.
It was what the centaurs had been waiting for - Grawp's outstretched fingers were a foot from Harry when fifty arrows soared through the air at the giant, peppering his enormous face, causing him to howl with pain and rage and straighten up, rubbing his face with his enormous hands, breaking off the arrow shafts but forcing the arrowheads in still deeper.
'Let's go,' he said.
'OK,' he said, but did not move. He had just heard something. There were faint whispering, murmuring noises coming from the other side of the veil.
A few of the centaurs looked worried now. Hermione, however, gave a gasp.
I'd have felt it, he told himself, his heart now hammering against his Adam's apple, I'd already know . . .
'Fine!' Harry said loudly, as his scar gave another throb. 'Now can we move?'
'Is it those mad horse things?' said Ron uncertainly, staring at a point slightly to the left of the Thestral Harry was patting. 'Those ones you can't see unless you've watched someone snuff it?'
'I don't - ' Harry began. He swallowed. 'In the dreams I went through the door at the end of the corridor from the lifts into a dark room - that's this one - and then I went through another door into a room that kind of . . . glitters. We should try a few doors,' he said hastily, 'I'll know the right way when I see it. C'mon.'
'Who's Grawp?' Luna asked interestedly.
'And they left you behind?' asked Ginny, looking astonished.
Harry did not know what 'hagger' meant, or what language it was from, nor did he much care; he was watching Grawp's feet, which were almost as long as Harry's whole body. Hermione gripped his arm tightly; the centaurs were quite silent, staring up at the giant, whose huge, round head moved from side to side as he continued to peer amongst them as though looking for something he had dropped.
