A/N:Don't know where this bizarre idea hit me, but I'm gonna go along with it. So, just let me type up the story and see where it goes. I'm a fan of Harry Potter and some of the minor characters but I really hate how the Wizarding World operates, so I'm gonna be frank here and just say this story will be quite AU from the conventional series. I do not own Harry Potter or Pandora Hearts.

One: Nothingness

"You are nothingness, Oz Vessalius," Jack Vessalius whispered, getting down on his hands and knees and hovering over the other being who shared his body with him, "You destroy everything!"

Oz looked at him in confusion, Jack knew the other was not capable of comprehending such cruelty yet. It was just a plush rabbit that knew nothing of the world besides its annoying cries for Alice to help it. What need did he have to help the boy, no,thing, when no help had been extended to him throughout either of his lives?

He frowned as he thought back over that last statement. Lives...if you counted the many times his soul had rewound due to the Abyss rejecting his soul, he supposed he had lived many lives as Oz "Vessalius", and then as Jack Vessalius, but still there was always only one spot his damned mind would return to: the place he had been murdered at before he had wound up being born to his mother and father one hundred years ago.

Jack Vessalius paused for a moment, allowing Oz to breathe for a moment. His pretenses of maintaining a happy facade was gone. He would not allow the boy to see what he originated from just yet. Perhaps he could...explain things to the boy and maybe settle things out between them. That would be nice. The blond pushed his ponytail out of his face and sat down, staring at his green robes...green, the color he hated, the color of his damned eyes...it had never changed and he knew it never would.

His fists tightened so hard as he stared at his reflection, glaring at the green Vessalius eyes that glared back, but those eyes were also a reminder of the past he'd hoped he'd completely thrown away and left to rot in the pits of hell like it was.

For you see, Jack Vessalius was not always Jack Vessalius. Once upon a time ago, or perhaps in another lifetime, he was in fact Harry Potter, the boy who lived, or who met a tragic end at the hands of his relatives, way before his fifteenth birthday, in fact.

No, he frowned, he had been fifteen when his other life had met its end at the hands of his damned relatives. Jack could only laugh at the cruelty of which his other life had ended. He had been forced, year after year, to languish in torment, emotional abuse and pain at the hands of his loving relatives, and then go back to that wretched place, that place where he was blamed for everything that went wrong, where he was liked by no one and where everyone hated him and thought his existence a curse.

Yes, it had been after the death of the boy named Cedric or Frederick, Jack mused, it had been around one hundred years or more since his first death, and the memories were starting to fade. But he could still remember the cruelest ones, no they stayed in his mind regardless of how much he wanted to push them down to the surface.

He recalled the look of wicked joy on Uncle Vernon's face as he locked the door behind them, and how his aunt and Dudley had turned on him and started to ask him how invincible he really was. Then they started to hurt him and torture him. One day, he recalled how his life had ended.

He had been thrown outside and beaten by his dear uncle and then his loving uncle had decided to take him to his traditional spot-and he had used a tire iron to beat him into blissful unconsciousness and then, as he lay there bleeding, had walked away calmly.

It had been winter, also. So he had also frozen to death. Wasn't that pathetic, the great Boy-Who-Lived, the great savior of the Wizarding World, had not died in battle heroically against Voldemort, but had instead been murdered by the elements and his uncaring relatives, who were only Muggles and one of which was a fat pig who couldn't do anything if he wanted to.

Then he had once again been reborn as Jack Vessalius, mercifully his scar had not returned and he didn't need glasses this time around. However, his eyes still stayed that same damned shade of emerald-green that he was really starting to despise. Thankfully, his hair had lightened and was blond. He really did like himself better as a blond.

However, once again he was stuck with abusive relatives, only it was his own damned parents who had taken part in it; his father here had almost-he would say bloody but found it too outdated for his tastes-abused him but he thought better of it and ditched his mother, who afterwards decided to treat her son like garbage.

Harry Potter, or Jack Vessalius, could safely say the happiest time of his life was with Lacie. If only he had someone like Lacie around in his old life, someone who always believed in him. Lacie was so sweet and kind and gentle. She accepted Jack instead of mistreating him.

Yet, the life he had been born into was once again, filled with evil to the core and more child abuse was going on, uninvestigated and ignored. Jack was filled with rage upon learning that the so-called heroes of the Abyss had willingly murdered their own siblings because of the different color of their irises and essentially Revis had been the one responsible for making Glen as messed up as he was.

Their whole twisted system claimed to be justice when it was nothing but a joke-hmm, didn't that sound familiar-they killed children and used them as slaves in their little games when all they desired was control-they also claimed to be acting for the better good by hiding the truth from ordinary muggles and using this power for only themselves.

Jack couldn't give a damn about the Baskervilles, but now that they were back and trying to ruin his life again, he had to stand up, had to do something. He had lost the love of his life, had been forced to age again and again, and now he was being threatened again? He glanced over at Alice, sweet lovable Alice.

He recalled seeing her tear her throat out with great remorse. Lacie would have never wished death upon her children, and she would judge him for allowing that to happen, he knew. Alice and Alyss...regardless of whether or not they were a means to an end, that didn't mean that he didn't come to care about them, because he had. Yes, even annoying, bratty Alice was to be missed.

But she had come back and taken Oz away from him, depriving him of his power. Yet again he had to endure more agony for 100 years. Having Oz as a companion wasn't a bad thing in and of itself, the rabbit had an interesting mind and was sharper than he appeared. Plus, the two of them had a mutual enemy this time: Zai Vessalius.

Jack held his face in his hands, cursing whoever had decided to make him suffer this much throughout his lifetimes. He just wanted to die. Life was hell without Lacie, without the old Oswald, without Alice...

"Jack?" Oz's voice called out. The boy was watching him.

"Oz, you are B-rabbit, not Alice." Jack whispered before presenting him with an image of his doll self. "You are the first B-rabbit and were Alice's closest companion before you gave Lacie's memories to me and crumpled into pieces. There were two bodies you used and one was turned into a chain by the Will of Abyss for me to use to destroy the world for Lacie. That was you, Oz. You became a chain, but when Alice took your powers you lost all your memories and assumed you had always been human. That is your sin."

"So I'm not real?"

"Yes," Jack whispered.

"So everyone has been using me this whole time? So, my life is a lie and no one actually loves or cares about me?" Oz whispered. Oh, god, that hit so close to home. The blond Vessalius shuddered.

"...Alice did. She gave up her life to help you, Oz. You were my tool years ago." Jack said.

"Jack...why do you hate your eyes so much?" Oz asked sharply.

Jack froze. "What?"

"You're always looking like you want to pull out your own eyes like the Will of Abyss did to Break."

"Oz...you aren't the one who is nothing. I am," Jack said softly. As the cursed, wicked human lay there, wondering over his past life memories, he wondered, what would they think of him now?

Oswald was a dead-ringer for Severus. Hence why they hadn't gotten along from the start. But Alice and Alyss were refreshingly innocent, sweet young girls who knew nothing of lying wizards, of lies and half-truths. Yet he had done the same thing the horrid Headmaster had done to him.

Jack stopped upon hearing a soft voice call out. It must have been coming from the boy who possessed Oswald now.

"...Jack, no, Potter, why have you become like this?"

Jack's eyes narrowed in fury upon hearing that name, that disgusting name he had disassociated himself with. He surrounded himself with B-rabbit's chains again, oblivious to how Alice was crawling on the ground moaning in pain and Oz was begging him to stop.

"Glen, my name is Jack Vessalius. I know nothing of this Harry Potter. Only one thing is certain:you stand in my way to get Lacie back."

Oswald, no-Severus stood his ground, getting back up. "You're still the arrogant bigheaded brat, Potter. Has anything at all changed?" He growled. "Oh, yes, it has. You're a brutal, violent, selfish, psychopathic killer now."

"No, on the contrary, Glen, I am quite sane. I have just-" He opened his eyes, which were now blood-red due to Oz's power being unleashed as he held B-rabbit's scythe, "Opened my eyes to reality. Goodbye, Glen."

The scythe came down on Glen again as everything went black.

Jack chuckled as he stood over Glen. "What? Did you honestly think I was that same naive, gullible little boy you could keep in line by using little threats to keep me in check? No, I'm not that disgusting, little annoying, pretentious brat. I've grown up, Severus, or Oswald. You shall die."
