Children raised in neglectful, harsh or downright abusive homes are far more mature than their age would suggest. Learning to keep yourself fed, watered, how to avoid getting hurt, and the plans to do so forces this maturity to come early. A young boy of Number 4 Privat Drive named Harry Potter was no different.

As he got over the initial shock of the situation Harry forced himself to focus on a bit of information Hagrid had said. The man who killed his parents was still out there, biding his time. Harry felt a cold chill creep over him as that singular thought froze him to the core. His mind locked on this single thought, a chilling numbness washing over him.

Then something seemed to click in his head. It was the same sort of feeling he had after the Dursley's were being especially mean towards him. A turning of the fear into resolve, of chilling fear into cold-forged hatred. The man who had killed his parents was still out there.

Harry had long resolved that the first chance he could the Dursley's would pay back the slights paid to him with steep interest. Now another name joined to this exclusive list and he would destroy this man for taking his parents from him.

OOOOOOOOOOOOOOOOO

Vernon was not a nice man by any definition of the word. Small-minded, petty, cruel, and vindictive would be some of the nicer ways to describe the whale of a man. One thing Vernon was not though was stupid. He had a vile and sadistic intelligence to him, one that had served him well, one that Harry was aware of. So, in returning to the Dursley's house he approached his uncle with a message that would appeal to the vile man.

"There's an evil freak out there killing regular folks and I want your help in killing him!"

OOOOOOOOOOOOOOOOO

Harry had several lists in his mind, the first was one for those who would suffer most dear for their actions against him. After that, the names became more of those who had paid him great insult or minor injury. Then slight insult yet meant to harm. The rest had been those to remember for future fault.

Snape had stamped his name in the second list and was approaching the point where Harry would have to act against the man. Well, at least that had been the truth until his first Quidditch match. The man had attempted to kill him! Only through Hermione setting the prick on fire had he managed to survive. Snape had made his stance clear, and so Harry would reply in turn, with interest.

OOOOOOOOOOOOOOO

Harry held the smooth material in his hands as Ron prattled on about how amazing a gift it was in the background. The invisibility cloak in his hands held a key to the answer to his problems. He had thought it would take far more time to put debts back to rights. Now though this changed things, debts would come calling soon.

OOOOOOOOOOOOOOOOO

There was a silence across the Great Hall as Dumbledore continued his speech on the tragic events of today.

"Professor Snape, Students Malfoy, Parkinson, Nott, and Goyle have passed today. The terrible accident in the 1st year Potions class today has come as a most violent shock to us all today. I have canceled classes for the rest of the week while we take this time to mourn for those lost."

As he continued to speak to the assembled school Dumbledore was of mixed emotions. Losing Snape and several Slytherin first years was a great tragedy. That Harry Potter had managed to shatter many bones in his left arm earlier today was fortunate.

It was due to this he that had missed the tragedy, was a sign of the prophecy coming into play he was sure. After all, what was a temporary injury compared to dying from a cauldron explosion? This was Fate herself showing her hand in keeping Harry from death!

OOOOOOOOOOOOOOOOO

Harry knew that shaved Erumpent Horn was explosive unless handled with care. Snape had told them what cabinets were dangerous until he cleared them to use. What Harry had not taken into account though was how explosive they were. Sneaking into the Potions classroom under his invisibility cloak had been difficult. Tossing a handful of the shavings into Malfoys cauldron without anyone noticing had been difficult as well.

He was glad he had then started running after tossing them. The shavings had taken around 10 seconds to react enough to explode. This was enough time for him to get out and Snape to make his way over the to Cauldron.

The resulting explosion had blown the room to hell and back. He was thankful he had gotten clear enough to not be further injured. Rushing back to the infirmary had sealed his alibi. No one suspected him of having anything to do with the accident. Harry sighed in contentment, he had already started to pay debts owed, life was looking up.

OOOOOOOOOOOOOOOOO

As he saw the man who had killed his parents growing out of the back of Quirrell's head, only one all-pervading thought came over him. Here was the man who had killed his parents! Letting the only action he would thank his uncle for take over, Harry reached into around to his back. With a smooth action, he drew, aimed and fired at center mass of Quirrell. After emptying the clip Harry smiled, his uncle had been right.

Wizard or not, a bullet or five to the chest will kill anyone.

OOOOOOOOOOOOOOO
