‘I am sorry not to have been more help,’

‘I am sorry not to have been more help,’ said Nick gently. ‘Well ... well, do excuse me ... the feast, you know ...’

And he left the room, leaving Harry there alone, gazing blankly at the wall through which Nick had disappeared.

Harry felt almost as though he had lost his godfather all over again in losing the hope that he might be able to see or speak to him once more. He walked slowly and miserably back up through the empty castle, wondering whether he would ever feel cheerful again.

He had turned the corner towards the Fat Lady's corridor when he saw somebody up ahead fastening a note to a board on the wall. A second glance showed him it was Luna. There were no good hiding places nearby, she was bound to have heard his footsteps, and in any case, Harry could hardly muster the energy to avoid anyone at the moment.

‘Hello,’ said Luna vaguely, glancing around at him as she stepped back from the notice.

‘How come you're not at the feast?’ Harry asked.

‘Well, I've lost most of my possessions,’ said Luna serenely. ‘People take them and hide them, you know. But as it's the last night, I really do need them back, so I've been putting up signs.’

She gestured towards the noticeboard, upon which, sure enough, she had pinned a list of all her missing books and clothes, with a plea for their return.

An odd feeling rose in Harry; an emotion quite different from the anger and grief that had filled him since Sirius's death. It was a few moments before he realised that he was feeling sorry for Luna.

‘How come people hide your stuff?’ he asked her, frowning.

‘Oh ... well ...’ she shrugged. ‘I think they think I'm a bit odd, you know. Some people call me “Loony” Lovegood, actually.’

Harry looked at her and the new feeling of pity intensified rather painfully.

‘That's no reason for them to take your things,’ he said flatly. ‘D'you want help finding them?’

‘Oh, no,’ she said, smiling at him. ‘They'll come back, they always do in the end. It was just that I wanted to pack tonight. Anyway ... why aren't you at the feast?’

Harry shrugged. ‘Just didn't feel like it.’

‘No,’ said Luna, observing him with those oddly misty, protuberant eyes. ‘I don't suppose you do. That man the Death Eaters killed was your godfather, wasn't he? Ginny told me.’

Harry nodded curtly, but found that for some reason he did not mind Luna talking about Sirius. He had just remembered that she, too, could see Thestrals.

‘Have you ...’ he began. ‘I mean, who ... has anyone you known ever died?’

‘Yes,’ said Luna simply, ‘my mother. She was a quite extraordinary witch, you know, but she did like to experiment and one of her spells went rather badly wrong one day. I was nine.’

‘I'm sorry,’ Harry mumbled.

‘Yes, it was rather horrible,’ said Luna conversationally. ‘I still feel very sad about it sometimes. But I've still got Dad. And anyway, it's not as though I'll never see Mum again, is it?’

‘Er—isn't it?’ said Harry uncertainly.

She shook her head in disbelief.

‘Oh, come on. You heard them, just behind the veil, didn't you?’

‘You mean ...’

‘In that room with the archway. They were just lurking out of sight, that's all. You heard them.’

They looked at each other. Luna was smiling slightly. Harry did not know what to say, or to think; Luna believed so many extraordinary things ... yet he had been sure he had heard voices behind the veil, too.

‘Are you sure you don't want me to help you look for your stuff?’ he said.

‘Oh, no,’ said Luna. ‘No, I think I'll just go down and have some pudding and wait for it all to turn up ... it always does in the end ... well, have a nice holiday, Harry.’

‘Yeah ... yeah, you too.’

She walked away from him and, as he watched her go, he found that the terrible weight in his stomach seemed to have lessened slightly.

The journey home on the Hogwarts Express next day was eventful in several ways. Firstly, Malfoy, Crabbe and Goyle, who had clearly been waiting all week for the opportunity to strike without teacher witnesses, attempted to ambush Harry halfway down the train as he made his way back from the toilet. The attack might have succeeded had it not been for the fact that they unwittingly chose to stage the attack right outside a compartment full of DA members, who saw what was happening through the glass and rose as one to rush to Harry's aid. By the time Ernie Macmillan, Hannah Abbott, Susan Bones, Justin Finch-Fletchley, Anthony Goldstein and Terry Boot, had finished using a wide variety of the hexes and jinxes Harry had taught them, Malfoy, Crabbe and Goyle resembled nothing so much as three gigantic slugs squeezed into Hogwarts uniform as Harry, Ernie and Justin hoisted them into the luggage rack and left them there to ooze.

‘I must say, I'm looking forward to seeing Malfoy's mother's face when he gets off the train,’ said Ernie, with some satisfaction, as he watched Malfoy squirm above him. Ernie had never quite got over the indignity of Malfoy docking points from Hufflepuff during his brief spell as a member of the Inquisitorial Squad.
