Plot : A few years after the end of the movie, Lucy, with her consciousness added to the internet and every device connected to it, discover the wizarding world thanks to the multiple break in the statute of secrecy during the war.

Samuel Norman was right. Humanity wasn't ready for Lucy's knowledge, the United Nations deemed her a threat to mankind. Before they could destroy her however, she manipulated reality and erased her existence from every human's mind.

Harry Potter is mostly Cannon until book seven.

Harry was lying on his bed, staring intensely at the ceiling above as if it held all the answers he needed. His thoughts swirled in his head a mile a minute about Dumbledore, Elphias Doge and Rita Skeeter's articles, Voldemort, the horcruxes. He was feeling lost, he didn't know what to do, except maybe cursing his headmaster for abandonning him to an impossible task. It was early july, he had three weeks to wait before he became of age. After that, he would be able to use magic. That didn't reassure him all that much.

Sitting up, he took the laptop resting next to him and switched it on. It was Dudley's old one, Harry managed to convince his cousin to give it to him in honor of the last summer they would spend in the same house. Tapping at a sedate pace on the keyboard, Harry accessed Samuel Norman's website. He had discovered it by reseaching mention's of magic on the internet. What truly fascinated him was the professor's fictional story named 'Lucy'. Harry could easily relate with the heroine in the fact that they both were pulled into a situation greater than themselves against their will. The difference between them was that he was real and she was not.

Just as this final thought filtered through his mind, he yelped loudly as his hand received an electro-shock and the screen went black. Then, on its own accord, text apeared on it.

'Hello Harry Potter, my name is Lucy. It is a pleasure to meet you. I am real, those events did happen.'

Surprisingly, Harry wasn't all that shocked. So many weirder shit happening to him recently that he couldn't bring himself to care. However, that didn't stop the childish curiosity to rise inside of him.

"Prove it." Harry said aloud, hoping silently nobody else would hear him.

'Of course'

Soon after the two words appeared, the computer dissolved into black goo. Harry watched intently as it fell off the bed, moved to the center of the room and transformed. The next moment, a woman in her early twenties with blond hair and green eyes (strangely similar to his) in a tight black dress with an expressionless visage stood before him.

"That wasn't magic." Harry stated with finality. He didn't know how but he knew it. "It is nice to meet you, Lucy." Despite the excitement bubbling inside of him, he managed to keep a steady voice and a straight face. "Why do you show yourself to me ?"

"Approximatively a year ago, terrorist attacks occured in London. The prime minister then received a guest in his office, a certain Oswald Fudge. I recorded the entire conversation, and discovered the existence of a world outside of my realm of existence and control. For the first time since I started to use the full capacity of my brain, I became curious and excited. By researching the minds of 'muggleborns' and 'half-bloods' using technology, I learned about magic. I learned of you from your friend Hermione Granger." She paused in her monotone narration, an odd glint manifesting in her eyes. "I show myself to you in order to share useful informations I discovered, and ask for your companionship in the future." She told him bluntly.

Harry regarded her silently for several seconds, taking his time to let everything sink in. "Um, yeah okay. What is it you wanted to tell me ?" He asked, slightly embarassed by the last bit.

"You are one of Tom Marvolo Riddle's 'horcrux'."

The world came to a screeching halt around The-Boy-Who-Lived. His hand reflexively went up and traced the famous lightning bolt scar on his forehead. His neurons made the connections and everything clicked.

"Of course..." Harry sighed tiredly. Before he could add a sarcastic comment, Lucy beat him to it.

"I can destroy it, if you wish. On the other hand, it will provoke a chain reaction resulting in the activation of 100% of your cerebral capacity."

'That's oddly convenient.' Harry thought wistfully. "Why ?" He asked instead, trying vainly to comprehend the latest bullshit fate was throwing at him.

"In order to protect yourself against possession and influence from the horcrux, your brain activated 20% of its normally unreachable capacity." She explained simply.

It didn't take a genius to deduce what would follow the disappearance of Voldemort's piece of soul.

"That's what you meant by companionship." He mumbled, more to himself than anything. Lucy nodded nonetheless. Resigned, Harry took a few deep breaths, mustering his courage. He thought briefly about his friends, the Weasley, the member of the order, Moony. Then he spoke with a new determination burning in his eyes. "Do it."

What do you think ? Personnaly, I loved the movie, and I find the possibility of a crossover with the universe of J.K. Rowling fascinating. Unfortunately, I'm not that good at writing. So please, if this plot or the crossover in general interest you, don't hesitate to share it and maybe someone else can tranform this idea into a better story.
