Dean Thomas and Seamus Finnigan had reached the dormitory first and were in the process of covering the walls beside their beds with posters and photographs. They had been talking as Harry pushed open the door but stopped abruptly the moment they saw him. Harry wondered whether they had been talking about him, then whether he was being paranoid.

'Hi,' he said, moving across to his own trunk and opening it.

'Hey, Harry,' said Dean, who was putting on a pair of pyjamas in the West Ham colours. 'Good holiday?'

'Not bad,' muttered Harry, as a true account of his holiday would have taken most of the night to relate and he could not face it. 'You?'

'Yeah, it was OK,' chuckled Dean. 'Better than Seamus's, anyway, he was just telling me.'

He got into bed and made to pull the hangings closed around him, but before he could do so, Seamus said, 'Look… what did happen that night when… you know, when… with Cedric Diggory and all?'

Seamus sounded nervous and eager at the same time. Dean, who had been bending over his trunk trying to retrieve a slipper, went oddly still and Harry knew he was listening hard.

Seamus looked for a few seconds as though detention would be a reasonable price to pay to say what was going through his mind; but with a noise of contempt he turned on his heel, vaulted into bed and pulled the hangings shut with such violence that they were ripped from the bed and fell in a dusty pile to the floor. Ron glared at Seamus, then looked at Dean and Neville.

'Anyone else's parents got a problem with Harry?' he said aggressively.

'My parents are Muggles, mate,' said Dean, shrugging. They don't know nothing about no deaths at Hogwarts, because I'm not stupid enough to tell them.'

'You don't know my mother, she'd weasel anything out of anyone!' Seamus snapped at him. 'Anyway your parents don't get the Daily Prophet. They don't know our Headmaster's been sacked from the Wizengamot and the International Confederation of Wizards because he's losing his marbles -'

Harry felt a rush of gratitude towards Neville. Nobody else said anything. Seamus got out his wand, repaired the bed hangings and vanished behind them. Dean got into bed, rolled over and fell silent. Neville, who appeared to have nothing more to say either, was gazing fondly at his moonlit cactus.

'Does he think he'll turn into a nutter if he stays in a room with me too long?' asked Harry loudly, as the hem of Seamus's robes whipped out of sight.

'Don't worry about it, Harry,' Dean muttered, hoisting his schoolbag on to his shoulder, 'he's just…'

But apparently he was unable to say exactly what Seamus was, and after a slightly awkward pause followed him out of the room.

The one good thing to be said for this lesson was that it was not a double period. By the time they had all finished reading the introduction of the book, they had barely ten minutes left for dream interpretation. At the table next to Harry and Ron, Dean had paired up with Neville, who immediately embarked on a long-winded explanation of a nightmare involving a pair of giant scissors wearing his grandmother's best hat; Harry and Ron merely looked at each other glumly.

'And your name is?' Professor Umbridge said to Dean.

'Dean Thomas.'

'Well, Mr Thomas?'

'Well, it's like Harry said, isn't it?' said Dean. 'If we're going to be attacked, it won't be risk free.'

'I repeat,' said Professor Umbridge, smiling in a very irritating fashion at Dean, 'do you expect to be attacked during my classes?'

'No, but -'

Professor Umbridge talked over him. 'I do not wish to criticise the way things have been run in this school,' she said, an unconvincing smile stretching her wide mouth, 'but you have been exposed to some very irresponsible wizards in this class, very irresponsible indeed - not to mention,' she gave a nasty little laugh, 'extremely dangerous half-breeds.'

'If you mean Professor Lupin,' piped up Dean angrily, 'he was the best we ever -'

'Hand, Mr Thomas! As I was saying - you have been introduced to spells that have been complex, inappropriate to your age group and potentially lethal. You have been frightened into believing that you are likely to meet Dark attacks every other day -'

'It is my understanding that my predecessor not only performed illegal curses in front of you, he actually performed them on you.'

'Well, he turned out to be a maniac, didn't he?' said Dean hotly. 'Mind you, we still learned loads.'

'Your hand is not up, Mr Thomas!' trilled Professor Umbridge. 'Now, it is the view of the Ministry that a theoretical knowledge will be more than sufficient to get you through your examination, which, after all, is what school is all about. And your name is?' she added, staring at Parvati, whose hand had just shot up.

'Hem, hem,' said Professor Umbridge, employing the same silly little cough she had used to interrupt Dumbledore on the first night of term. Professor McGonagall ignored her. Seamus handed back Harry's essay; Harry took it without looking at him and saw, to his relief, that he had managed an 'A'.

'Right then, everyone, listen closely - Dean Thomas, if you do that to the mouse again I shall put you in detention - most of you have now successfully Vanished your snails and even those who were left with a certain amount of shell have got the gist of the spell. Today, we shall be -'

'Overall,' said Professor Umbridge, returning to Professor Grubbly-Plank's side after a lengthy interrogation of Dean Thomas, 'how do you, as a temporary member of staff- an objective outsider,

First came Neville with Dean and Lavender, who were closely followed by Parvati and Padma Patil with (Harry's stomach did a back-flip) Cho and one of her usually-giggling girlfriends, then (on her own and looking so dreamy she might have walked in by accident) Luna Lovegood; then Katie Bell, Alicia Spinnet and Angelina Johnson, Colin and Dennis Creevey, Ernie Macmillan, Justin Finch-Fletchley, Hannah Abbott, a Hufflepuff girl with a long plait down her back whose name Harry did not know; three Ravenclaw boys he was pretty sure were called Anthony Goldstein, Michael Corner and Terry Boot, Ginny, closely followed by a tall skinny blond boy with an upturned nose whom Harry recognised vaguely as being a member of the Hufflepuff Quidditch team and, bringing up the rear, Fred and George Weasley with their friend Lee Jordan, all three of whom were carrying large paper bags crammed with Zonko's merchandise.

'I can't see Madam Pince being too chuffed with us doing jinxes in the library,' said Harry.

'Maybe an unused classroom?' said Dean.

'Yeah,' said Ron, 'McGonagall might let us have hers, she did when Harry was practising for the Triwizard.'

It was immediately apparent on entering the Great Hall that Umbridge's sign had not only appeared in Gryffindor Tower. There was a peculiar intensity about the chatter and an extra measure of movement in the Hall as people scurried up and down their tables conferring on what they had read. Harry, Ron and Hermione had barely taken their seats when Neville, Dean, Fred, George and Ginny descended upon them.

'Did you see it?'

'D'you reckon she knows?'

'What are we going to do?'

They were all looking at Harry. He glanced around to make sure there were no teachers near them.

'Right,' said Harry vaguely, putting down the bottle and continuing to watch the corner. Umbridge had just got to her feet. 'Ha,' he said softly, as she strode between two lines of desks towards Snape, who was bending over Dean Thomas's cauldron.

It seemed, however, that he was not the only person in Divination who was in a temper. Professor Trelawney slammed a copy of the Oracle down on the table between Harry and Ron and swept away, her lips pursed; she threw the next copy of the Oracle at Seamus and Dean, narrowly avoiding Seamus's head, and thrust the final one into Neville's chest with such force that he slipped off his pouffe.

There was a gentle knock on the door. Harry looked round. Gmny, Neville, Lavender, Parvati and Dean had arrived.

'Whoa,' said Dean, staring around, impressed. 'What is this place?'

'It's bizarre,' said Fred, frowning around at it. 'We once hid from Filch in here, remember, George? But it was just a broom cupboard then.'

'Hey, Harry, what's this stuff?' asked Dean from the rear of the room, indicating the Sneakoscopes and the Foe-Glass.

'Dark detectors,' said Harry, stepping between the cushions to reach them. 'Basically they all show when Dark wizards or enemies are around, but you don't want to rely on them too much, they can be fooled…'

'Well, that was pretty good,' said Harry, 'but we've overrun, we'd better leave it here. Same time, same place next week?'

'Sooner!' said Dean Thomas eagerly and many people nodded in agreement.

Harry felt himself positively swelling with pride as he watched them all. True, Neville did Stun Padma Patil rather than Dean, at whom he had been aiming, but it was a much closer miss than usual, and everybody else had made enormous progress.

They pulled off their robes and put on pyjamas in silence; Dean, Seamus and Neville were already asleep. Harry put his glasses on his bedside table and got into bed but did not pull the hangings closed around his four-poster; instead, he stared at the patch of starry sky visible through the window next to Neville's bed. If he had known, this time last night, that in twenty-four hours' time he would have kissed Cho Chang…

'It wasn't a dream… not an ordinary dream… I was there, I saw it… I did it…'

He could hear Seamus and Dean muttering but did not care. The pain in his forehead was subsiding slightly, though he was still sweating and shivering feverishly. He retched again and Ron leapt backwards out of the way.

He tried to get out of bed but Ron pushed him back into it; Dean and Seamus were still whispering somewhere nearby. Whether one minute passed or ten, Harry did not know; he simply sat there shaking, feeling the pain recede very slowly from his scar… then there were hurried footsteps coming up the stairs and he heard Neville's voice again.

'Weasley, you ought to come too,' said Professor McGonagall.

They followed Professor McGonagall past the silent figures of Neville, Dean and Seamus, out of the dormitory, down the spiral stairs into the common room, through the portrait hole and off along the Fat Lady's moonlit corridor. Harry felt as though the panic inside him might spill over at any moment; he wanted to run, to yell for Dumbledore; Mr Weasley was bleeding as they walked along so sedately, and what if those fangs (Harry tried hard not to think 'my fangs') had been poisonous? They passed Mrs Norris, who turned her lamplike eyes upon them and hissed faintly, but Professor McGonagall said, 'Shoo!' Mrs Norris slunk away into the shadows, and in a few minutes they had reached the stone gargoyle guarding the entrance to Dumbledore's office.

Hogwarts without the others, which would keep them safe over the holidays at least… but no, that wouldn't do, there were still plenty of people at Hogwarts to maim and injure. What if it was Seamus, Dean or Neville next time? He stopped his pacing and stood staring at Phineas Nigellus's empty frame. A leaden sensation was settling in the pit of his stomach. He had no alternative: he was going to have to return to Privet Drive, cut himself off from other wizards entirely.

'Can't wait to see what Umbridge thinks of you going public,' said Dean, sounding awestruck at dinner on Monday night. Seamus was shovelling down large amounts of chicken and ham pie on Dean's other side, but Harry knew he was listening.

'That's right,' said Neville, nodding, 'and his Death Eaters, too… people should know…'

Neville left his sentence hanging and returned to his baked potato. Seamus looked up, but when he caught Harrys eye he looked quickly back at his plate again. After a while, Dean, Seamus and Neville departed for the common room, leaving Harry and Hermione at the table waiting for Ron, who had not yet had dinner because of Quidditch practice.

The dormitory door opened; Dean and Seamus came in. Harry swung his legs back into bed. He did not want to look as though anything odd had just happened, seeing as Seamus had only just stopped thinking Harry was a nutter.

Ron took an unnecessarily large gulp of water; Harry saw it spill over his chin on to his chest.

'Harry,' he said, as Dean and Seamus clattered around noisily, pulling off their robes and talking, 'you've got to tell -'

'I haven't got to tell anyone,' said Harry shortly. '1 wouldn't have seen it at all if I could do Occlumency. I'm supposed to have learned to shut this stuff out. That's what they want.'

'Herd?' said Lavender in a confused voice, and Harry knew she was thinking of cows. 'What - oh!'

Comprehension dawned on her face. 'There are more of youT she said, stunned.

'Did Hagrid breed you, like the Thestrals?' asked Dean eagerly.

Firenze turned his head very slowly to face Dean, who seemed to realise at once that he had said something very offensive.

'I didn't - I meant - sorry' he finished in a hushed voice.

'Centaurs are not the servants or playthings of humans,' said Firenze quietly. There was a pause, then Parvati raised her hand again.

'Harry, I think I'm doing it!' yelled Seamus, who had been brought along to his first ever DA meeting by Dean. 'Look - ah -it's gone… but it was definitely something hairy, Harry!'

'Cool!' said Seamus, who was silhouetted against the window. 'I think one of those Catherine wheels hit a rocket and it's like they mated, come and see!'

Harry heard Ron and Dean scramble out of bed for a better look. He lay quite still and silent while the pain in his scar subsided and disappointment washed over him. He felt as though a wonderful treat had been snatched from him at the very last moment… he had got so close that time.

'An owl will be sent to you some time in July' said Professor McGonagall.

'Excellent,' said Dean Thomas in an audible whisper, 'so we don't have to worry about it till the holidays.'

Meanwhile, Ron was reading two years' worth of Charms notes with his fingers in his ears, his lips moving soundlessly; Seamus Finnigan was lying flat on his back on the floor, reciting the definition of a Substantive Charm while Dean checked it against The Standard Book of Spells, Grade 5; and Parvati and Lavender, who were practising basic Locomotion Charms, were making their pencil-cases race each other around the edge of the table.

They traipsed back to the Gryffindor common room to find it full. The commotion out in the grounds had woken several people, who had hastened to rouse their friends. Seamus and Dean, who had arrived ahead of Harry, Ron and Hermione, were now telling everyone what they had seen and heard from the top of the Astronomy Tower.

'Oh, blimey,' said Lee Jordan, covering his mouth. 'It's me who's been putting the Nifflers in her office. Fred and George left me a couple; I've been levitating them in through her window.'

'She'd have sacked him anyway' said Dean. 'He was too close to Dumbledore.'

Harry didn't answer, but flung himself out of the room and began to fight his way through the milling crowds outside. Two floors up he met Seamus and Dean, who hailed him jovially and told him they were planning a dusk-till-dawn end-of-exams celebration in the common room. Harry barely heard them. He scrambled through the portrait hole while they were still arguing about how many black-market Butterbeers they would need and was climbing back out of it, the Invisibility Cloak and Sirius's knife secure in his bag, before they noticed he had left them.

`Well, I always thought he was a bit of an idiot,' he said, prodding his queen forwards towards Harry's quivering castle. `Good for you. Just choose someone - better - next time.'

He cast Harry an oddly furtive look as he said it.

`Well, I've chosen Dean Thomas, would you say he's better?' asked Ginny vaguely.

WHAT?' shouted Ron, upending the chessboard: Crookshanks went plunging after the pieces and Hedwig and Pigwidgeon twittered and hooted angrily from overhead.
