Rose Potter and the Self-Insert Chapter 1, a harry potter fanfic

Chapter One: Prisoner of Azkaban, Part One

Elliot

Elliot decided Rose Potter was a strange girl.

Of course, he realized she was a strange girl since he woke up in an obvious alternate universe of Harry Potter and met her at the Leaky Cauldron in Diagon Alley, but now he was even more certain she was a strange girl. Because on a dark and stormy night, aboard the Hogwarts Express in their compartment, the very same strange girl sat across from him with a book which appeared to be made of sewed human skin…

"What is that…?" Elliot asked hesitantly.

"A book." Rose answered dryly.

The twelve-year-old witch had pale white skin, medium messy black hair, green eyes behind black round glasses, and black nail polish and she wore the Hogwarts uniform with the colors and the symbol of Slytherin House. A long black robe with green back lining and the Slytherin coat of arms, long sleeve white blouse with a green and silver tie, black skirt, long black socks, and black shoes.

He wore a similar outfit but with a long sleeve white button shirt, black pants, and short black socks. He hadn't been sorted into a house yet so his colors were plain black and gray with the Hogwarts coat of arms.

"Obviously." Elliot deadpanned.

"Don't worry. This book is harmless. Mostly." Rose said plainly.

"Right…" Elliot deadpanned again.

"Now hush and enjoy the view outside. After all, it's a dreadful night…" Rose said with a ghost of a smile on her lips.

Elliot gave up and looked out the window at the passing countryside. He thought about the coming events of the third year. It had been some time since he last read the books or watched the films and he couldn't help but feel like he was forgetting something important right about now…

Outside, lightning flashed across the dark and stormy night sky, illuminating several floating dark monsters…

Rose

Rose Potter decided Elliot was a normal boy.

Of course, compared to the other students she attended Hogwarts School of Witchcraft and Wizardry with, he was only slightly more interesting than them. His sudden appearance at the Leaky Cauldron in Diagon Alley and his American accent made the fact he was a transfer student obvious to her. But strangely, when they met, he seemed to both recognize her and not recognize her. She thought he might have just been familiar with her title.

The Girl-Who-Died.

But she still wasn't certain. However, she would wait to discover the truth. She didn't need any more complications in her life. Any more complications had no place in her life. Despite her life only being filled with complications. Regardless, she already had enough to deal with.

The orphanage she returned to every summer, the headmistress of the orphanage, the children of the orphanage, the castle she returned to every school year, the headmaster of the castle, and the students of the castle.

Oh, and the ghost of the dark lord too, she guessed.

Her green eyes glanced up at the boy who looked out the window at the passing countryside under the dark and stormy night. The thirteen-year-old wizard had brown skin, black hair, and brown eyes. He was normal. He was unremarkable in every way. He would likely be average in his studies too. He wouldn't challenge her in any way.

He would make a perfect husband.

Especially compared to the other boys in her year. She knew she had to continue and rebuild the Potter family as she was the last surviving member. She didn't care for the notion of love or sex but even she knew the latter was necessary… However, she could do worse though.

Like Ronald Weasley.

She visibly shuddered and her green eyes returned back to the Book of the Dead in her hands but her thoughts went back to her first two years at Hogwarts School of Witchcraft and Wizardry. Their first year Defence Against the Dark Arts professor, Quirinius Quirrell, was discovered by her, of course, to be in league with the not-so-dearly-departed dark lord, Voldemort, a terrible on the nose name, mind her, to retrieve the Philosopher's Stone and revive the latter completely as his body had been destroyed and he now remained a ghost.

But, of course again, she killed Quirrell and defeated ghost-Voldemort with her second favorite spell, the Severing Charm, as she hadn't learned her first favorite spell yet, the Fiendfyre Curse, which could only be described as living hellfire… She stopped herself from visibly shuddering in excitement in case Elliot was still pretending not to glance back at her every now and then… She didn't want to scare him. Not yet, at least.

But one day, she would learn that curse…

And then there was her second year. Little first year Ginevra Weasley, another fresh Weasley ginger for the grinder, was possessed by a… piece of Voldemort to awaken the "Great Slytherin Beast", or the Serpent of Slytherin, a female basilisk, hidden away in the Chamber of Secrets beneath Hogwarts which was weirdly only open from the girl's bathroom… But, of course once again, she destroyed the book that possessed the ginger and caused her second year long headache, defeated young ghost-Voldemort, and tamed the basilisk. What else was she supposed to do with the great living symbol of her house? The "Great Slytherin Beast"? The Serpent of Slytherin? The Queen of Serpents? Kill her?

She almost wanted to smile at such a thought.

But the Queen of Serpents was now rightfully under her command, both after recognizing her parseltongue ability which allowed her to speak to serpents and her general superiority, and as a reward for such wise recognition, she only saw fit to name her… Poppy… After her favorite flower… Oh, and she herself might have killed their second year DADA professor and celebrity fraud, Golderoy Lockhart, after he attempted to erase her memory and escape the Chamber of Secrets.

But the real tragedy was Ginevra Weasley would not leave her alone now…

She left her thoughts when the train came to a sudden stop. She hadn't moved an inch but Elliot fell out of his seat. Normal, indeed. But before she could chide him, the lights went out throughout the train, and she began to feel an almost delightful chill… Dementors, she realized. She didn't voice the answer to their current situation as she felt he also knew the answer considering the boy's expression changed from confusion to horrifying realization rather quickly. Slightly more interesting, indeed. But then the compartment door slowly opened and a dementor appeared from the darkness…

She couldn't help but feel slightly disappointed.

She imagined a more dramatic entrance. She would have to exaggerate its entrance in her manuscript. But it seemed to work on her companion as his expression changed to that of fear… She only hoped when she shared her manuscript with him, it would invoke the same emotion.

She then felt tired…

She knew what would happen next… Despite daydreaming about being in Azkaban herself… She couldn't fight the unfamiliar feelings building inside of her… Fear…? Sadness…? No, it couldn't be… But then she saw them… Her parents… Her father James Potter… Her mother Lily Potter… She didn't blame herself though… She blamed Bellatrix Black… She blamed their unfortunate resemblance… It must have been their raven black hair color… She would suffer for causing her these feelings… And she would suffer for resembling her… Wait…

What was he doing…?

The foolish boy got between her and the dementor… His arms wrapped protectively around her… She felt another unfamiliar feeling… Surprise…? Because to most… She was just a freak… But maybe he thought differently… But then she felt something else… Something different…

And it felt delightfully terrible…

As the cold embrace of darkness finally took hold of them both completely… She wrapped her arms protectively around him too… And Rose Potter made a deathly vow… If they both survived… He would never escape her…

And thus a ghost of a smile appeared on her lips…

(Kill of the Night - Gin Wigmore)

The street's a liar

I'm gonna lure you into the dark

My cold desire

To hear the boom, boom, boom of your heart

The danger is I'm dangerous

And I might just tear you apart

Oh, ah, oh

I'm gonna catch ya

I'm gonna get ya, get ya

Oh, ah, oh

I wanna taste the way that you bleed, oh

You're my kill of the night

Now you're mine

But what do I do with you, boy

I'll take your heart

To kick around as a toy

The danger is I'm dangerous

And I might just tear you apart

I'm gonna catch ya

I'm gonna get ya, get ya

Oh, ah, oh

I wanna taste the way that you bleed, oh

I'm gonna catch ya

I'm gonna get ya, get ya

Oh, ah, oh

I wanna taste the way that you bleed, oh
