Severus Snape woke in the infirmary at the school. He was confused for a moment before his memories caught up with him. When they did he began to shake as he reached for his wand.

"Easy Severus." Poppy was there waiting and handed him the wand he was after. He gave the wand a twirl and the date and time appeared, "You've not been here long. Do you remember what happened?"

"Potion exploded?" he asked.

"What were you experimenting on?" she wondered aloud, he never answered her when she asked so she didn't wait for one, "I'd prefer if you stay for a few more hours."

"I will be fine." He tried to make his voice gruff as it normally was.

"I knew you'd say that." She muttered as he shakily stood.

He waited a moment then moved from the room. His robes, as always, billowing behind him. He didn't get far before Albus accosted him.

"I'm surprised she let you out." He observed.

"I have many things to do." He replied with his normal scathing bite.

"I'm sure." Albus nodded, "What were you working on? It left some odd readings."

"I don't remember." He snarled, "I will be reviewing my notes to see what it was."

"Let me know when you figure it out." Albus left him as he turned to go down to the dungeons.

"Not bloody likely." He thought to himself as he walked to his lab.

Once he arrived he cleaned up the mess. There was no way he was telling Dumbledore that he had devised a potion to traveled back in time to stop the total annihilation of the wizarding world, especially since it was the old goat's fault. He was glad it was Saturday he needed to get to work on his project, he didn't have time for classes. At least it was December and the Holidays would start soon and he'd have more time.

He left the school and headed to Diagon Alley. His first stop was the pet store where he purchased a grey rat. He proceeded to cut off one of its toes and then healed it making sure to leave a scar. His next stop was the Weasley home. He was disillusioned as he hid behind a tree and watched the children playing in the snow.

The oldest boy in the orchard was the one he was looking for. He was sitting on a stone wall reading. The rat was in a cage not far from his side. He eased over and quietly unclasped the back of the cage and stunned the rat within. He switched them out and eased away with the marauder in his pocket and a plain grey rat, missing a toe, sitting in the cage. Once he was far enough away he apparated to the only person he was sure would seek out the whole truth.

"Snape, why are you pestering me on a Saturday?" Moody growled but let the man in.

"I saw a very distinct individual shrink down to this rat." Snape growled right back, "I remember seeing this form in HIS meetings."

"Who is it?" Moody glared at the rat.

"Peter Pettigrew." He frowned.

Moody forced him out of the animagus form and fed him Veritaserum before waking him up, "Name?"

"Peter Pettigrew." He warbled.

"Why did Black want to kill you?" Moody growled out.

"Because I gave James and Lily's location to the Dark Lord so he could kill Harry." He answered.

"Were you the Potter's secret keeper?" Snape asked.

"I was." He answered before being stunned again.

Moody then turned his wand and froze Snape before feeding him Veritaserum, "Name?"

"Severus Snape." He growled having forgotten how quick the old man was.

"Are you a spy for Dumbledore?" he asked.

"I was." He was forced to tell the absolute truth.

"What are you now?" he demanded.

"A time traveler." He answered, "I came back to stop the destruction of our world."

"Who is destroying it?" he demanded.

"Potter." Severus began to shake uncontrollably, "He is worse than the Dark Lord ever hoped to be."

"Did he take over the death eaters?" Moody started to plan.

"No he wiped them out." Severus was still shaking, "The things Dumbledore put him through broke him and now he destroys us for destroying him."

"Potter?" Moody dropped in a chair, "What can a kid do?"

"No he was eighteen in my world when I left. He'd been killing people for three years by this time." Severus explained, "You know you're his target when you wake up in the hospital bruised all over with seventeen broken bones."

"How is that worse?" Moody wondered.

"That's just the beginning." Severus shuddered, "He puts his victims though what Dumbledore made him go through. Few have survived, none of those few ever made it out of the Janis Thickney ward."

"So you came back to do what exactly?" He asked.

"If I can stop him from going through those things he will not break and think to use them." Severus sighed as he sat in a chair, "His first victims were the aurors that were supposed to be taking him to Azkaban. I was told the story since I wasn't there."

***Memory***

"It was all lies." Harry stated calmly looking at most of the Weasley clan several of whom looked shocked, "You never cared, you only wanted my money, my fame and my life."

At this moment you couldn't call Harry angry, not even livid would work. He was beyond it all. His so called friends had never been friends. He was being held by aurors after his trial had ended. They were taking him to Azkaban. The trial had been a true farce. Most everyone he knew was telling lies. He hadn't done those things. He had never hurt anyone. They had no proof at all, no one had even asked for any. They were railroading him just like Sirius.

"Just answer me this." Harry turned to his headmaster as he and the Weasleys waited with him for the boat to arrive, "Why are you doing this to me?"

"Harry you are far too powerful to be allowed out." Dumbledore looked like he was disappointed in him, "Not even I could stop you if you were to go dark. We just can't allow you to be free. You should have stayed dead."

Harry had died for a short time. It was after Voldemort had tried to possess him during the fight in the Department of Mysteries. Harry had met with Sirius in that place and he had told him to go back and finish what he'd started. Harry had woke up and sent a severing charm at Voldemort's wand arm but Dumbledore had hit him from behind and Harry's charm had taken off Voldemort's head when he had fallen forward.

"I should have stayed dead." Harry agreed before stepping onto the boat that had arrived, "You all better hope you never see me again, because if you do it will be as you die."

"Please don't Harry." Dumbledore offered a sympathetic grimace, "I would hate to have to kill you."

"I have no fear of dieing. I've already done that once." Harry smirked, "I also won't be dying by your hand. You'll farm it out to Moody or Snape. You never dirty your own hands. I wonder who killed Grindlewald for you. Oh, that's right you didn't. You just stunned him as you gave him hug. Now that's a good use for the power of love."

"Now Harry." He tried.

"Why don't you go take a trip to the Dursleys." Harry grinned nastily, "Get a nice good look into their heads so you will know who it is when I begin."

"Don't let the darkness take over Harry." Dumbledore implored him.

"I'm not dark, I'm crazy." Harry quipped back.

Three days later the boat bumped ashore. The two guards where beaten beyond recognition. Each of them had multiple broken bones. What was odd was that they both had exactly the same injuries.

***end***

"He was powerful enough to break out of the magical suppression cuffs." Severus shivered again, "The aurors said he basically overloaded them, then turned and asked who was going first."

"Forgot to disarm him?" Moody asked.

"No." Severus shook his head, "Dumbledore snapped his wand and you checked him for extras. He was able to do wandless, wordless magic."

"Why did I let him railroad the boy?" Moody wondered at what the second war had done to his sense of right and wrong.

"You didn't know." Severus answered, "Harry spared you because you had been shown some altered memories to prove he had done things. They couldn't use them in court because they were altered and it would have told. You were told I got them illegally. I was told you retrieved them so I was partially spared."

"Partially?" he asked.

"I was beaten and had seventeen bones broken." He nodded, "It was payback to me for how I treated him when he was a student. Since that time he has kept me around as a healer of sorts."

"What does that mean?" Moody asked.

"If he went too far I was to keep them from dying, if I could." Severus shuddered.

"The Weasleys knew he was innocent and still let him be put away?" Moody knew Arthur and couldn't believe he had done something like that to a child.

"Not all of them." Severus shuddered again, "Arthur and the twins didn't know until he was being put on the boat. They tried to fight for him at that time, but he told them not to waste their efforts he would be fine. Bill and Charlie weren't part of it because they worked outside the UK and barely knew him."

"How do you propose we do this?" he waved at the rat.

"Quietly." Severus sighed, "Albus can't know or he'll stop us. The muggles he put Harry with abuse him with Dumbledore's apparent consent. He is molding Harry into a weapon and by the time he's done Harry fits the mold perfectly. Then he just expects the boy to go to Azkaban quietly."

"He is an old fool." Moody agreed, "Let me give you the antidote."

"You know the funny thing." Severus said after he'd swallowed the potion, "After he was on the boat they went to Gringotts to claim his inheritance and it was gone. He had moved it all before his trial. They never figured out how he did it or where he put it. He was in the ministry cells before he found out what they were doing."

"Did he have any other friends?" Moody asked.

"The muggle born sided with the Weasleys." He sneered, "She was more worried about getting a good job at the ministry than she was about being his friend. It was stupid because Harry had far more clout to give her a leg up than they would have. Most of the rest either sided with them or stayed out of it. Longbottom was one of only two to side with Harry. A girl named Lovegood was the other. They were ostracized for their efforts, but they were the only ones alive in the end."

"Are you sure he won't go dark if we treat him well?" Moody asked.

"Positive." Severus nodded enthusiastically, "The bruises and broken bones are only the ones he received between the age of one and eleven. Anything he received after that he would do in the next phase of your torture. Each time he'd let you heal before he would start the next phase. He's creative and powerful enough to really torture people but he only gives out what he received."

"So why get Sirius out?" Moody finally asked.

"He died just before this all happened." Severus stated, "I think it was the final straw for Harry. When he was torturing Molly Weasley he'd bring in one of her children for a few minutes before taking them away. He'd do it over and over before coming back empty handed saying sorry they died, it was her own fault for hurting him like she did. He was only able to visit Sirius off and on since he was on the run and then he died because Harry went to the ministry after being tricked by Voldemort. He felt that Sirius' death was his fault. I think getting him out of the Dursley's house and into a safe place with Sirius is the best idea."

"Did he kill her children?" Moody asked.

"Once she was dead he started on the children involved. Ginny didn't make it past the basilisk venom and Ron lasted until he had to face the dragon." Severus explained where those two punishments came from.
