Harry walked into Professor McGonagall's Transfiguration class ten minutes late he walked up to the front of the room where Professor McGonagall sat at her desk. she looked up from the stack of essays she was grading, and her eyes narrowed behind her square spectacles.
"You're late Mr. Potter. I assume you have some sort of excuse," she said.
"Yes, Professor I was in the hospital wing I have a note from Madam Pomfrey," said Harry as he handed the tightly rolled scroll of parchment to his teacher, who slit it open with her wand she read the note quickly and her expression softened slightly.
"Everything seems to be in order, please take your seat," said Professor McGonagall and Harry walked slowly to the back of the class and sat down next to Ron, and Hermione.
"What's wrong?" asked Hermione.
"It nothing just a bit of a headache, and no, it wasn't my scar," said Harry before Hermione could ask.
"You've been getting a lot of headaches recently are you sure it's not something to worry about?" she asked
"I'm fine, Hermione; I think it's just an allergy to some sort of pollen or something my nose has been stuffy lately too," said Harry as he stifled a sneeze.
"Well as long as you don't get any worse I won't worry," said Hermione.
"If it gets any worse I'll go back to the hospital wing and have Madam Pomfrey check it out," said Harry as he felt another sneeze coming on his hand flew in front of his mouth and nose instinctively. A second later, he became very aware that the eyes of the entire class including Professor McGonagall were focused intently on him.
"What?" he asked.
"Harry, your hair it's purple," said Ron grinning widely.
"What are you talking about?" asked Harry.
"Here look," said Hermione as she pulled her compact out of her book bag and handed it to him.
Harry looked into the small round mirror, his jaw dropped his hair, which was normally jet black, and messy was instead short, neat, and a vibrant shade of purple.
"Oh crap, my hair, quick somebody, do something!" shouted Harry as Professor McGonagall came walking briskly over to the distressed young man.
"Hold on Mr. Potter," said the Professor as waved her wand in a long sweeping motion unfortunately for Harry whatever spell she tried had no effect on his hair she tried again, and again had no luck.
"What were you doing when this happened?" she asked.
"I sneezed," said Harry.
"You sneezed?" asked Professor McGonagall in a tone of disbelief.
"Yes, I sneezed; I've been feeling a little under the weather over the last few days. But I thought it was nothing-just allergies or a cold so I just ignored it. But when I didn't get better after a few days I went to see Madam Pomfrey that was a week ago and I've been back three times since then not counting this morning," said Harry.
"Has anything like this ever happened to you before?" asked Professor McGonagall clearly worried.
"No, nothing at least not since I started school. There was this one time when I was about seven or so and I turned my teacher's wig blue but that was accidental magic. Just a random bust of power that happened when I got scared not something I had control over," said Harry.
"And would you say you had control over what just happened?" asked Professor McGonagall.
"No, but this shouldn't be happening at all," said Harry.
"Try to concentrate and see if you can reverse the change," said Ron.
"What good, will that do?" asked Harry.
"I don't know I'm just trying to help," Ron said desperately.
"Here goes," said Harry as he screwed his eyes up in concentration he felt a strange tingling in his scalp as his hair began to grow longer and its color gradually returned to normal.
"Wicked," said an amazed Ron who was now staring open mouthed at his best friend.
"Yes that was quite an impressive bit of transfiguration. Well beyond anything, you should be capable of at this stage of your magical education. Unless you were born a Metamorphmagus," said Professor McGonagall.
"What's a Metamorphmagus?" asked Ron.
"A witch or wizard, who can change their appearance at will without the aid of potions or spells.
However, they're quite rare. I've only known a handful, and as far as I know, only one has been a student at Hogwarts in the last twenty years.
Her name was Nymphadora Tonks and she graduated the same year as your brother Charlie," said Professor McGonagall to Ron.
"What does that mean for me I've never been able to do anything like this before now?" said Harry.
"To be honest I have no idea but you seem quite alright for the moment so I think it would be best for you to get back to your studies," said Professor McGonagall.
The rest of the class went by without further incident and when the bell rang, Professor McGonagall excused everyone to lunch. Harry, Ron, and Hermione were among the first ones to reach the Great Hall and took their seats at the Gryffindor table.
Harry and Ron began helping themselves to food as soon as it appeared in front of them. Hermione rolled her eyes and calmly ladled stew onto her plate while talking with Nevel Longbottom, who was sitting across the table from her.
"Do you reckon the Ministry will catch Black soon?" asked Neville.
"I'm sure they will. I mean they even have the Muggles looking for him," said Ron.
"That's true but I don't think the Muggles know how dangerous he really is. I mean they think he's just an ordinary killer. They don't know that he killed thirteen people with a single curse," said Lavender Brown looking up from her copy of the Daily Prophet.
"Can we just eat without talking about Sirius Black?" asked Ginny.
"Yes, please," said Parvatai Patil.
"Okay I wonder what today's lesson in Defense Against The Dark arts will be," said Harry as he felt another sneeze coming on his hand flew to his mouth just in time.
"Ah-choo, Sorry it's these damned allergies," said Harry before he notice several pairs of eyes staring at him again although this time they were mostly Ravenclaws, and Hufflepuffs as most of those people who were sitting at the Gryffindor table had seen Harry's earlier transformation in class.
"Harry, your hair it's orange," said Katie Bell wearing a shocked expression.
"Oh, hang on Katie," said Harry as he returned his hair to normal.
"Maybe, you should go and see if Madam Pomfrey can do something for you Harry. I mean every time you sneeze your hair changes color," said Hermione.
"You're right I'll be right back," said Harry as he got up and walked out of the Great Hall and made his way to the hospital wing for the second time that day.
"Back again Mr. Potter?" asked Madam Pomfrey when she saw Harry enter the wing.
"Yes, Madam Pomfrey I have a bit of a problem. Every time I sneeze my hair changes colors," said Harry.
"Yes Minerva sent me a message just after you left her class this morning," said Madam Pomfrey.
"Can you do anything for me?" asked Harry.
"I can give you a potion to stop the sneezing but that's about it, I'm afraid," said Madam Pomfrey.
"Thank you, Madam Pomfrey," said Harry as he took the small dose of potion and returning to the Great Hall to finish lunch.
An hour later, Harry sat in his usual seat in the front of Professor Lupin's Defense against the Dark Arts class reading the chapter on vampires in his textbook.
A sudden wave of pain washed over him. His hand flew to his temple instinctively.
Ron looked around concerned, "What's wrong?" he asked.
"My head," moaned Harry.
"Is it your scar?" asked Hermione.
"No, It's my head," groaned Harry as his vision began to blur he blinked, trying to clear it.
Lupin looked up from his desk "Harry, what's wrong?" he asked.
"It's my head, I need the hospital…," began Harry but before he could get the last word out the room spun and he blacked out.
"Get him to Madam Pomfrey at once," said Lupin urgently as Ron and Hermione carried Harry out of the classroom and up to the hospital wing when they entered though the double doors Madam Pomfrey rushed out to meet them.
"Professor Lupin just told me what happened get him into bed so I can have a look at him," she said as Ron and Hermione carried Harry over to the bed and removed his shoes.
"I'm afraid I'm going to have to ask you to wait outside while I examine Mr. Potter," said Madam Pomfrey. Ron and Hermione nodded and stepped outside.
"I hope Harry is okay," said Hermione in a concerned voice.
"He'll be just fine. After all the stuff he's been through something like this is nothing, he fought You-Know-Who over the Sorcerer's Stone in our first year, and then last year he killed the Basilisk and saved Ginny," said Ron as he put an arm around her shoulders.
"You're right, I'm probably worried for nothing," said Hermione.
They sat in silence for about forty-five minutes before Madam Pomfrey emerged into the hall.
"Did you find out what was wrong with Harry?" asked Hermione.
"No Miss Granger, I'm afraid not. I've never seen anything like this in my entire career, and I have no idea what to do, but I've sent word of Harry's condition to an old colleague and friend of mine who lives in America, Gregory House to see if he and his team can help," said Madam Pomfrey.
"What makes you so sure this bloke can help Harry?" asked Ron.
"I've known Greg House longer than you've been alive, Mr. Weasley. if anyone can save Harry, it's he.
He's not only one of the greatest healers in the wizarding world, but also one of the top Muggle diagnosticians in the world I have complete faith in him," said Madam Pomfrey.
"May we go and see Harry?" asked Hermione.
"Yes, you may, but I'm afraid he's still unconscious," said Madam Pomfrey.
Hermione nodded and she and Ron stepped into the ward Hermione chocked back a sob when she saw Harry.
Ron pulled her into his arms and allowed her to sob into his chest for a moment before they turned to go.
