BEWARE!!!!!!

DIMENSIONS

Harry, stood gazing out of his window at privet drive, sadly contemplating the previous year. Thinking about what had happened at the ministry building made him want to scream with anguish. He was having nightmares like he had never previously thought possible.

The Dursley's were steering well clear of him and were only spoke to him when really necessary in overly cheerful voices, so as not to upset him - which would incur the wrath of a large group of wizards.

Harry started to feel slightly dizzy. 'Maybe I've forgotten to eat again' Harry thought. When he got lost in thought about what had happened, it was sometimes hours before he finally broke that chain of thought. Harry glanced at the repaired alarm clock on the bedside table; it read 6:00 am.

That meant he must have been awake all night, staring out of the window, part of Harry didn't care, what did it matter anymore anyway? The other part of him was currently concerned by the rate at which the dizziness seemed to be increasing.

The world was spinning faster and faster. Harry blacked out.

When he awoke, he found himself laying on the pavement in a deserted street that Harry did not recognise. He stood up. In the distance he could hear the shouts of a wand fight. Harry pulled out his own wand for protection and looked around.

Harry began to walk quickly from the sounds of the battle. "Expelliarmus!"

Harry's wand flew out of his hand. He turned and found himself face to face with none other than Remus Lupin and another man he did not recognise. They were both dressed in aurors uniforms.

Remus waved his wand. Ropes flew out of the tip and bound Harry tightly at the wrists and ankles. "What are you doing?!"

Remus and the other man approached him and grabbed him by each arm. Harry struggled. "What are you doing? Let me go!!" harry twisted out of their grips, but the ropes bound him too tightly and he fell, unable to thrust his arms out to take the fall.

When Harry came round the first thing he was aware of was a throbbing pain in the side of his head. He must have hit it when he fell. He opened his eyes to find that he was currently laying in a dimly lit room. He sat up and noticed that he was no longer in his jeans and sweater and was instead in a ragged brown set of robes,

Remus was standing in the doorway looking at Harry with a look of mingled anger and sadness. He pointed his wand at Harry "Get up."

Harry stood shakily. What was going on? Where was he? Was Remus a death eater?

"Professor please, what is happening?"

"What did you just call me?" Remus snarled

Harry stared, Remus's voice was filled with hate. This man was a far cry from the kind, quiet voiced man he thought he knew.

"you taught me defence against the Dark arts at Hogwarts. I just never got out of the habit of calling you professor.." Harry tailed off at the look on Remus's face

"What games are you playing? Until about four months ago I was-" he stopped suddenly, set his face into a neutral expression and approached Harry. He dragged Harry along a dark corridor.

As they walked Harry felt the waved of cold that could only mean one thing.dementors!

"No. Please!" Harry yelled as he was pulled closer to them.

They were walking along a corridor with barred doors on either side. Azkaban?

They stopped in front of an empty cell and Harry's eyes widened in horror. "NO!"

Remus opened the door and shoved Harry to inside, who stumbled to his hands and knees. He could only watch as Remus walked away. Then it hit him. The familiar feeling of falling through swirling white mist..cold.

//Lily, take Harry and go! It's him! I'll hold him off!//

//Not Harry! Please I'll do anything//

//Kill the spare//

//Harry.Take my body back will you?//

//There's nothing you can do Harry.nothing...he's gone//

// HE - IS - NOT - DEAD! SIRIUS!//

It seemed to last forever. A couple of times Harry was aware of being moved, but mostly there were just memories.

Gradually, the feeling began to subside. He was tied to a chair. There were voices around him.

"I didn't think he'd react to dementors like that, after only two days" Remus voice came, sounding more it's normal self.

"Maybe he's feeling guilty." Who's voice was that?

"I know this is hard James, but I've never seen the boy show any semblance of guilt." Remus replied softly.

James? Harry thought. He opened his eyes and found himself in a room containing what looked like almost every member of the Order of the Phoenix that he had ever met. Harry turned his head to the left and saw one of the people that had been haunting him for the last two days. It was his father!

Harry's fear and confusion became more profound as he looked at the face that was so like his own.

"Dad?" the man glared, his features hardening

"Don't call me that!"

Harry recoiled

"Just get on with is Albus!"

Minerva then spoke up "Is he to have the kiss?"

"No, not till he's 18, it's the law."

Albus walked up to Harry and unscrewed a bottle of clear liquid. As Harry remembered him doing with crouch, Albus forced a few drops into his mouth.

Immediately Harry felt calm, like he wasn't really there.

"What is your name?"

"Harry Potter,"

"How old are you?"

"15"

seemingly satisfied, Albus stood and motioned for Minerva to begin taking notes.

"Where is Sirius Black?"

"He's dead."

"What?!"

"Bellatrix Lestrange killed him."

"Didn't she die five years ago?" Remus whispered to James, who shrugged.

"What were you doing when you were captured?" Albus asked evenly

"I was lost."

"You were lost?"

"Yes."

"How did you become 'lost'?"

"One minute I was looking out of the window, and the next I was in the middle of a street."

"How did you get there?"

"I don't know. Maybe-"

"THIS IS REDICULOUS!" James shouted, snapping Harry out of his potion induced state of calm "He can obviously resist veritaserum!"

Dumbledore stood back "I am forced to agree. Remus, take him back to his cell."

Remus untied Harry and began to pull him back to the door. Filling with terror, Harry struggled, shouting "NO! I haven't DONE anything. Please! I can prove it, Uncle Vernon will tell you. NO-"

James had stepped in as Harry struggled and at this hit him, hard, across the face.

"After everything you've done, torture, rape, murder, you still deny it! We've all seen you! Just shut up!"

Harry was dumbstruck. Some distant part of his mind remembered Hermione telling him about parallel universes. Could he have somehow been transported to one?

Remus and James continued to pull Harry along the corridor, when in the other direction came running Snape and Peter (!).

"James, Remus." Peter puffed "We've got him!"

"Huh?"

"Harry Potter!" Peter exclaimed

"Who's that?" Snape asked suddenly

"Harry." Remus said

The four adults looked at each other in bemusement.

"I think I've been pulled here from another world" Harry said bravely through the cut lip his father had give him "This world - everything's wrong."

Remus and James looked carefully at the boy they were restraining. He looked the same as 'their' Harry except "Where did you get that scar?" Remus asked sharply

"Voldemort tried to kill me when I was a baby. Mum stopped him."

"This is a trick." Snape said "Take him to a cell and we'll work out what's going on here."

**James POV**

As James pulled his struggling son along the corridor, his head was spinning. What if this boy was telling the truth? He could be imprisoning an innocent.

Since Harry had been bought in, James had forbidden Dumbledore from telling anyone, except Lily, of course, and the members of the order that had been around when Remus announced his capture of Harry.

He had the surprise of his life when he arrived in Harry's cell and seen him pale and shaking on the floor. He had expected to see him his usual cold, emotionless self. Hard cold eyes that seemed to bore through to your very soul.

When he had called him 'Dad' eyes wide and scared, James thought he was going to faint. Then he had remembered the manipulative teenager who had tortured Remus.

This Harry was different, his eyes were like his mothers, every emotion reflected in their depths. He seemed incapable of harming anyone.

James sighed in confusion. Eventually, he and Remus reached a cell.he took the boy inside and left him, locking the door. He watched as Harry fell to the floor, face white as snow, muttering incoherently under his breath.

"Do you believe he's from another world or just another trick of Voldemort's?"

"I don't know." James answered honestly

"He called me professor. If it's an act, it's a very good one. But then, having been a prisoner of his, I wouldn't put anything past him."

James walked with Remus to the fireplace that would return them to Hogwarts. In Dumbledore's office, Severus and Peter were informing the others of their arrest.

"He struggled, cursed us. Eventually we stunned him after about an hour and dragged him to Azkaban."

James and Remus described their experiences with Harry.

"How can we tell though? Asked Minerva

"And who's to say that if he is from another world, he isn't as bad as our Harry?" Remus added.

Severus who had been looking pensive for the last few moments, cleared his throat impressively. All heads turned to him.

"We could always use a potion."

"What?" said Dumbledore abruptly

"There is a poison that has been used in the relatively small number of cases in the past. Make him drink it. If he is telling the truth, then his molecular structure will be very slightly different and he will not be affected."

"And if 'it' is from this world?" Peter asked

"It'll hurt. And we all know what a terrible shame that would be."

"Will it be lethal?" Remus asked

"Unfortunately not." Severus said, smirking.

James's expression darkened but he remained silent.

Albus ordered Severus to make the potion and contact them when it was complete. James went to update Lily on what had happened.

**Harry's POV**

three days had passed in Azkaban and the memories were becoming almost too much to bear. Loosely Harry wondered if he was screaming, he wanted to. How had Sirius been able to last so long?

Again the memories abated. Harry groaned and yanked his eyes open. This time he found himself staring into the face of his mother. Harry stayed silent and took in her face, the familiar green eyes looking back at him dubiously.

"He's awake." She said quietly

Harry was currently laying on the floor of Dumbledores office. Remus picked him up and sat him in a chair. Harry was too exhausted to bother trying to struggle. He just wanted to sleep peacefully. He closed his eyes and leaned back, ignoring the room full of people.

"Harry." Dumbledore said sharply, shaking Him.

Harry looked tiredly up at him.

"I need you to drink this."

"What is it?" Harry asked, voice hoarse.

"It will prove whether or not you are from this world." Harry stared at it.

"You are going to drink it. If you refuse, we will make you." Snape said irritably

Dumbledore handed the vial to Harry who downed the potion in one. Harry sat there expecting something horrible to happen. All he felt was a slight tingling in his arms and legs. The others were staring at him expectantly.

"It should have worked by now." Snape said

"So it's true? He's from another world?" Lily asked

"yes."

Hope filled Harry "So you're not going to send me back to Azkaban?"

"We need to ask you some questions first."

"You're not going to use veritaserum again are you?"

"I'm afraid we must." Dumbledore replied

Harry lowered his head. How much longer was this hell going to continue?

**James's POV**

Now that it was proven that this was another Harry, the differences became more apparent. He was more polite and seemed honest. Two qualities that his Harry never demonstrated.

When Peter and Severus had bought his son in James and Lily went to see him.

He was leaning against the wall; face blank, those cold eyes staring emptily ahead. No matter what he was experiencing on the inside, none of it showed. Lily had then demanded to see this other Harry.

He was worse than last time James had seen him. The boy was laying weakly on the floor, shaking harder, tears coursing down his face, quiet moans of anguish escaping him. It was Lily's comment that disturbed him most.

"This is our son. Who he should be."

When Voldemort had taken their infant son and raised him, brainwashed him, he had always wondered what he would have been like. However, as he began committing atrocities, James found he wondered less and less.

"What makes you say that?"

"He's showing emotion. I've never seen him do that before. I think he's telling the truth."

James wasn't sure whether he agreed or not. He had seen some pretty sick 'tricks' over the years.

"I wonder what he's been through. To act like this." Lily had muttered quietly.

When snape's potion had been completed, it struck James how thin Harry was. Apparently he had to be force fed to eat anything over the past 5 days, it looked like it had been going on longer than that though.

Now that he knew Lily was right he could quite plainly see that Voldemort had not raised this boy.

"You're not going to use veritaserum again are you?"

"I'm afraid we must."

Dumbledore raised a bottle of clear liquid.

"No!" James snapped suddenly "Look at him, he's exhausted, starved and emotionally drained. Let him sleep."

Harry than made eye contact. Gratitude obvious on his face.

"Alright. I want him watched at all times though."

"James and I can do that." Lily said.

**Harry's POV**

"James and I can do that."

Harry raised his head, surprised. HIS parents were going to spend time with him. Okay so that thought he was a murderer, but all the same, it was his family. Perhaps he could convince them of his innocence.

James picked Harry up, grimacing slightly at the large bruise he had given him. Harry relaxed slightly and allowed himself to be carried to the hospital wing.

Lily tucked him into a bed after helping him change into a clean set of PJ's. She then sat on the bed next to his with James, arms around each other.

The silence was awkward. Harry was desperate for something to say to them, but exhaustion overcame him and he fell asleep.

His dreams were full of the images he had seen in Azkaban. He felt himself being shaken awake. His mothers face came into focus above him.

"Mum?" he said drowsily. Lily's eyes showed great sadness but she nodded anyway.

"You were clutching that scar on your forehead." she said worriedly

James also looked concerned. "You said you got it when Voldemort tried to kill you."

"Yeah." Harry took a deep breath "When I was one Voldemort came to our house. He killed my dad and tried to kill me, but mum wouldn't let him." James and Lily held hands "she begged him to kill her instead so he did. The he turned his wand on me and cast Avada Kadavara"

"What?" James asked in shock "And you lived?!"

"Mum's sacrifice protected me. The curse rebounded and hit him. Voldemort's body was destroyed."

"He died?" Lily asked

"No. But it took him 13 years to get his body and powers back."

James and Lily looked at Harry appraisingly, as though too stunned to know what to say.

"It made me famous. I'm known as the 'boy-who-lived'"

"What happened to you without us?"

"I was supposed to live with Sirius" Harry gulped " but Peter who betrayed you - he was secret keeper - framed him for murder and faked his own death."

"He did what?"

"Yeah. Sirius was sent to Azkaban. He escaped as padfoot three years ago" a lump was forming in Harry's throat.

"Who did you live with then?" Lily asked

"Your sister's family."

"Petunia? But she hates me. She would have treated you horribly!"

"It wasn't fun." Harry said evenly not wishing to elaborate further.

"I can imagine."

Harry told them what had happened in the graveyard, but was unable to discuss the following year because the memories were too raw. He found himself breathing deeply, trying to keep calm.

"You and our Harry are so different." Lily commented. James left the room to tell Harry's story.

"Why does he so those things?"

"A long time ago it was prophesied that Harry or another boy would one day destroy Voldemort. (Harry sighed at this) I guess, he thought, if an enemy that powerful was being born, one that he could get to early enough he could somehow brainwash the child to work with him rather than against him. So that's what he did. He ignored Neville, who did not seem powerful enough and raised my son as his heir. Second in command. We all know that if he steps out of line Voldemort will kill him, but he's too brainwashed. Everything he thinks comes from Voldemort, or Sirius Black."

"Sirius?!"

"Yeah. He is different in this world. He betrayed us by kidnapping our son for Voldemort and helping to raise him to be evil."

Harry didn't know what to say. Both of them sat there barely restraining themselves from tears. As Harry was about to mount a defence for his Sirius, his mother spoke up

"I know you're not MY son but."

"Yes?"

"Can I hug you?"

Harry put his arms around the woman and it wasn't long before they were both crying for what they had lost.

A/N wow. Long chapter. Wrote this on paper months ago. Had to modify it to account for OOTP. Let me know what you think. Should I carry on?
