James and Remus came out of the dormitory 10 minutes later. They found Sirius fuming in the corner with his potions textbook open in front of him. He determinedly kept his head down as James came towards him.

'Pad?'
'What?' Sirius snapped.
'It wasn't me.'
'What?' Sirius repeated but in a softer tone and looked up.
'It wasn't me. I swear on the marauder's map it wasn't.'
Sirius stared at James for a moment then grabbed his arm 'come on we're going to see Dumbledore.'

They ran to the hospital wing and found the bed that "James" had been in was sealed off. 'Madam Pomfrey? Is Dumbledore still here?'
Madam Pomfrey was bustling around in her office and didn't look round to see who was talking 'No, he went back to his office.'

James and Sirius legged it out of the hospital wing and to Dumbledore's office.
'Professor Dumbledore?'
'Ah, Mr. Black, come in and ….Mr… Potter?' Dumbledore frowned at James, 'Would you care to explain?'
'Yes sir, me and Remus went back to the dormitory after you told us to, and we found James already there. He says he had no idea who the person in the hospital is.'
'I see…'
Dumbledore was silent, he looked up seemingly meditating.
'Sir?'
Dumbledore looked down.
'Do you know who he is?'
'No Mr Potter, I am afraid I do not. All I am sure of is that he is not James as the two of you kindly pointed out to me. I have had the area sealed off due to the nature of his injuries and it is a good thing that I have done so. He is still unconscious but rest assured that I will find out who he is once he is awake.'
'Yes sir,'
'Thank you sir.'
'Pleasant dreams.'
'Thank you sir, you too.'
Harry woke up a week later to find himself in the hospital wing, with only vague memories of arriving there. He remembered the fight with the death eaters, being thrown through the window and the blue light encompassing him and transporting him to Hogwarts, but that was it. He had no idea how long he had been here for, but guessed that it was over three weeks because he could hear students in the background.
He looked up to find professor Dumbledore and madam Pomfrey at his side. He quickly averted his gaze, he wasn't sure if he anted to talk to Dumbledore after their conversation at the end of last year, after Sirius' death, where he had learned about the prophecy, during which he had demolished half his office.
Dumbledore smiled at him and spoke first.
'Well sir, quite a fright you gave us there, arriving out of nowhere with your injuries.'
Madam Pomfrey nodded, 'Yes, quite right headmaster, collapsed lung, internal bleeding, two broken ribs, not to mention all the bruises.'
'I trust you are feeling better.'
'Yes,' mumbled Harry.
'Then perhaps you could enlighten us on the circumstances that resulted in your arrival here.'
Harry frowned, had no one told Dumbledore what had happened? He remained silent trying to contemplate exactly what it was Dumbledore didn't know, or was trying to find out.
Dumbledore prodded him, 'How about starting with your name.'
Harry raised his eyebrows, 'My name?'
'Yes,' answered Dumbledore simply.
'You don't know my name?' asked Harry disbelievingly, had someone removed Dumbledore's memory.
'Should I?'
Harry looked at Madam Pomfrey, 'You don't know my name either?'
She shook her head.
'What is going on?' Harry demanded.
'We were hoping you would tell us.'
Harry could feel the anger bubbling up inside him, was this one of Dumbledore's tricks to "protect" him?
'So you're telling me that no one from the ministry, the order, the Weasley's, Ron or Hermione told you.'
Dumbledore shook his head. At this point Harry lost it, Dumbledore was definitely lying to him.
'WHAT IS GOING ON? LAST YEAR YOU PRETENDED I WAS INVISIBLE, THIS YEAR YOU ARE GOING TO PRETEND THAT YOU DON'T EVEN KNOW ME. IS THIS ANOTHER OF YOUR CRACKED UP PLANS TO PROTECT ME? TO KEEP ME IN THE DARK? IS IT? OR IS IT JUST SOME SICK JOKE? DO YOU THINK I HAVENT BEEN THROUGH ENOGH IN MY LIFE? YOU THINK I CANT HANDLE THE TRUTH. HAVE YOU ALREADY FORGOTTEN WHAT HAPPENED TO SIRIUS LAST YEAR?' By now Harry had tears of anger, of sadness and of betrayal streaming down his face, and he made no effort to stop them. 'SIRIUS DIED BECAUSE YOU DECIDED IT WAS UNNECESSARY TO TELL ME ABOUT MY LIFE! I'M SICK OF IT! SICK! AND YOU KNOW WHAT I'M LEAVING!'
in truth Harry of course had no idea of where he would go, but made to get out of bed anyway. Dumbledore laid a hand on his shoulder.
'My dear boy, you need rest, and Sirius, do you mean Sirius Black?'
'What other Sirius' do we know?' Harry snapped.
'Sirius is alive and well, I believe it was he who brought you here.'
Harry threw Dumbledore a dirty look, then shook his hand roughly off his shoulder, jumped out of his bed and turned towards the exit.
Dumbledore sighed as he watched the troubled boy, wondering what he had missed.

Harry found himself in the corridor outside the hospital wing. He made his way fuming to the Gryffindor Tower, but even through his anger, he realised that he didn't recognise any of the faces he passed and a slight panic began within him; surely there couldn't be that many new first years.
He reached the portrait of the fat lady "Password?"
'Er…'
'No password, no entrance.'
'Oh come on I can't be bothered right now.'
The fat lady pursed her lips.
Harry let out a roar of frustration, and began pacing hoping that someone would come soon. He didn't wait long.
'Hey James,'
Harry spun round, he looked at the boy behind him, he looked vaguely familiar, but Harry couldn't quite put his finger on it, and the boy had just called him James!
'Forgot the password?' he asked brightly.
Harry didn't answer; he just regarded him suspiciously, trying to work out who he was. The boy raised an eyebrow, 'You okay?'
'Er… I don't mean to be rude but who the hell are you?'
The boy looked disbelievingly at Harry, then his face cracked into a grin, 'This is another one of your pranks isn't it, its not going to work on me.'
'Pranks?' said Harry blankly, 'I don't do pranks.'
'Yeah whatever, and I'm Bob Marley.'
Harry began to panic as he started to fit things together, just one more piece on info and he would know.
'Bob, could you tell me what the date is.'
'it's the 17th.'
'of?'
'September.'
'What year is it?'
'1978,' the boy answered cautiously, not sure where the conversation was headed.
'SHIT! SHIT! SHIT!' Harry turned and ran, it all made sense now, this was why he was being called James, this was why Dumbledore had no idea who he was, this was what he meant by Sirius being alive and well.
'Hey James, come back! Whats going on?'
Harry didn't look back, he needed to see Dumbledore. He sprinted towards his office nad stopped outside the gargoyle. Desperately he started naming sweets, 'Bertie botts, chocolate frogs, sugar quills.'

The gargoyle moved aside, Harry ran up the stairs and flung the door open without bothering to knock. He stopped in front of Dumbledore's desk, his breathing becoming difficult, he must have strained his collapsed lung, 'Professor Dumbledore' said Harry in-between gasps.
Dumbledore stood up and helped Harry into a chair.
'Take your time.'
Harry sat still for a while trying to regain his composure. His breathing steadied and he began to talk.
'Professor, I think I'm from the future...' A/N: im tempted to stop here, but that would make the next chapter too short, so count yourselves lucky.
'The future? What do you mean?'
'My name is Harry Potter.'
'Potter? I thought you had some potter blood in you, please continue.'
'yes… well my dad is James potter and my mum is Lily Evans. When I came it was the year 1998.'
'I see… well Mr Potter, would you care to explain how you got here.'
Harry briefly explained his encounter with the death eaters. '… and then there was this blue light and I ended up here.'
'Interesting. Well until I can find a way for you to return you will need to stay here.'
'But sir… I haven't got any stuff.'
'That is not a problem, I will have some stuff sent up to your room, but first we need to determine which house you are in.'
'I'm in Gryffindor.'
'And which year?'
'Sixth'
'Ah yes with the marauders.' Said Dumbledore with his eyes twinkling, 'Was there anything else you wished to tell me.'
'No sir.'
'Okay well that's sorted, but I think we should change your name. Harry will be okay buy potter will need to be changes. Any suggestions?'
