The summer of Harry's 17th birthday was the summer that Harry snapped. When he was picked up by his aunt and uncle, they immediately threw him back into the cupboard under the stairs and burned everything that had to do with the Magical World with the exception of Harry's wand, since it wasn't in his trunk. They refused to feed him and they only let him out of his "room" so he could shower and relieve himself. Harry was forced to sit on his cot, staring at the door, waiting for the next time the door would be open.

It was two weeks into the summer that Harry mentally snapped. He waited until he saw the sun go down and he heard Vernon snoring before he slipped his wand out from under his pillow and unlocked his "bedroom" door. He calmly walked into the kitchen and grabbed the butcher knife before he slowly and silently walked up the stairs and into Dudley's bedroom.

He stood there watching Dudley sleep before he moved over to the side closest to Dudley's head. He raised the knife and embedded it into Dudley's brain. Harry twisted the knife, making sure Dudley was dead before he reached down and checked Dudley's pulse, there wasn't one. He smiled darkly before he pulled out the knife and walked out of the room; he shut the door and walked to his "family's" room. He growled softly and walked over to his aunt. He slit her throat and watched her thrash around, blood spurting from her throat and coating Harry in her life essence.

"What the hell? POTTER!" Vernon was awake now and he stared at Harry's bloody figure.

"Now it's your turn." Harry said calmly before he lunged at his uncle and stabbed him 15 times until Vernon stopped moving.

Calmly, Harry stood from Vernon's mangled body and went back downstairs to be greeted by 4 Death Eaters and Bellatrix. She opened her mouth to say something but was interrupted by Rodolphus, "Why are you covered in blood and why do you have a knife?" He said slowly, not wanting to scare the boy.

Harry didn't say a word, he just looked up to the landing before he walked upstairs, only looking back to see if the Death Eaters were following him.

Bellatrix and Rodolphus looked at each other before following Harry up the stairs and to his cousin's room. They waited for Harry to open the door and they both gasped. They stared at Dudley's mangled body and Bellatrix smiled, "Why did you kill your cousin, Harry?"

Harry still stayed silent and turned towards his Aunt and Uncle's room. Rodolphus walked to the open door and gagged. As a Death Eater, he had seen a lot and done a lot but never had he seen so much damage done by a child as small as Harry.

"Bella, you need to see this."

Bellatrix walked over to her husband and she laughed, "My, my Harry. Why did you kill them?"

"They locked me in the cupboard, never fed me. I was done, they needed to die."

Rodolphus shuddered, Harry sounded like a robot, no emotion whatsoever.

"I want to see Tom."

Bellatrix's jaw dropped, "You want to see the Dark Lord?"

Harry nodded and dropped the knife to the floor, he turned and walked downstairs. Rodolphus stopped Bellatrix before they headed downstairs, "Are we sure about this? I mean, hell, look what he did to the family."

"It isn't something that I would have done but he does have potential." Bellatrix said softly before walking downstairs.

"You ready to go, Potter?"

"Yes."

Bellatrix cocked an eyebrow before grabbing Harry's arm and disappearing with a crack.

"Bellatrix, what is this? I thought I said to bring him unharmed." Lucius said as he looked Harry over.

"It's not his blood." Rodolphus said as he appeared behind Bellatrix.

"Whose is it?"

"He murdered his Aunt, Uncle and cousin." Bellatrix said as she laid Harry down on the floor.
