I just taking a short break from my science notes and my other fic College Life to write this. There will be more chapters. It will be a next generation/PJO crossover. I woke up with this idea in my head and decided to write it.

Prologue

Teddy stood and King Cross Station, ready to board the train that would take him to Hogwarts, the finest school of witchcraft and wizardry. He was nervous about staying away from his godfather Harry, meeting new people, being sorted... Most of all, he was worried about people not accepting him for being part werewolf.

Harry squeezed his hand.

"Don't be nervous. I still remember when I stepped on to the platform for the first time, scared and lost in the wizarding world. But look where Hogwarts led me, great friends I can rely on, a happy life away from the Dursleys, a godfather...and you."

Teddy felt a lot better.

"Where's Victoire?" He asked, looking around for his friend. He and Victoire were the oldest of the Weasley bunch, and is the only ones in their family attending Hogwarts this year.

Out of the corner of his eyes, something caught his attention. A lone girl about his age was leaning against a pillar on the platform, trunk by her foot. She had no parent or relatives with her and she didn't look scared or nervous at all. In fact, she looked amused. There was something different about her, though Teddy couldn't tell what. She wore muggle clothing, but so did many half-bloods and muggle born. Maybe it was her confidence, the way she carried her self and absentmindedly twirled her wand. Or maybe it's her features, too perfect to be human. Exotic silver-blue eyes filled with amusement and mischief, drawing people in, making them want to know more. Her skin was fair, her hair was not messed up in the slightest, even after squeezing through hoards of people to get to the station.

What ever it is, Teddy knew she was different from the other.

"Teddy! TEDDY!" Teddy turned his head at the sound of his name. Victoire was running over, excited about going to Hogwarts. Soon he was chatting away with his best friend, forgetting all his worries and nervousness.

But the mystery of the girl on the platform never left his mind.

He saw her again later in the common room. She had also been sorted in Gryffindor, though she wasn't present at the ceremony. No one else noticed her absence.

But Teddy did.

She stood by the window, gazing out into the distance. Teddy noticed her hand fingering a silver charm necklace, one he hadn't seen on the platform. The pendant had a symbol on it. It looked familiar, yet Teddy couldn't place a word for it.

Steeling himself, Teddy decided to talk to the girl. To find out more about her.

The girl had seen him approach and was watching him with a calculating look. It was almost as if she was wondering about his next move, determining whether or not he was a threat.

"I'm Teddy Lupin. What's your name?" Teddy figured it would be best to introduce himself first.

At first the girl didn't answer, still scanning him over. Teddy's palms are slick with sweat and he wonder if it was a bad idea. It seemed like an eternity had passed before the girl came to the conclusion that he was not a threat.

"Reagan. I'm Reagan Andromeda Black."

Black. She was a Black. The symbol on her charm necklace was the symbol of the noble house of the Blacks. Teddy's godfather's godfather was a Black. Harry had told Teddy about the Blacks, or more specifically Sirius and Regulus Black. Sirius was Harry's godfather, a brave man who died fighting against Voldemort. Regulus was a death eater that didn't want his future. He didn't want to live his life killing muggle borns. He died fight for what was right, he died for the horcrux.

Reagan was the daughter of one of them. If it was Andromeda or Bellatrix or Narcissa, she would have a different name. But no, her last name was Black, she was the daughter of either Regulus or Sirius. Teddy mused to himself, in order for her dad to be Regulus, she would have to be at least in her early adult years. So the only option was Sirius.

Merlin, her father was Sirius! One of the greatest man on earth, Teddy's idol. From what Harry told him, Sirius was one of his father's best friend. But this also raised a lot of questions for Teddy. Why does Harry not know that Sirius had a daughter? Who was her mother? Shouldn't she be the one inheriting number twelve Grimmauld Place? He had so much questions to ask but the only thing that came out of his mouth was:

"Are you serious?" Reagan laughed at his question, somehow knowing what went on in his head in the last two minutes.

"No, but that's my dad." She grinned, revealing pearly, white teeth.

Slowly they became friends, talking about the war with Voldemort, have serious discussions on topics like how people treat half breeds, sneaking into the kitchen to rejuvenate after a late night study session. Sometimes Victoire would join them, but mostly she kept to her own group of friends in Ravenclaw.

But that didn't stop Teddy from noticing different thing about her.

That didn't stop Teddy from feeling like there's something Reagan was hiding.

Teddy's suspicions grew after an eventful potion lesson.

They were learning to brew a potion that heals cuts and bruises when Alan McHill's caldron exploded. Unfortunately for Reagan, she was sitting right of him. The chunky, gooey, brown substance splatter all over Reagan's robes.

The class was suddenly silent. Thirty pair of eyes watched intrigued. Alan sputtered an apology and inched backwards, fearing for the worst.

For some reason, everyone was scared of Reagan. She wasn't necessarily scary-looking, unlike Jimmy Nelson with his black clothes and skulls. She didn't go around hexing people or bullied others. It was the fire in her eyes, an eternally burning fire that lit up whenever she talk about a topic she loves or when someone she cares about is hurt. The fire signifies her never ending energy and standing for what she think is right. The fire makes other feel weak, it made others feel like they don't know half of what she had been through.

But it wasn't just it. Reagan radiated confidence and coolness. She unintentionally made others feel like she was above them, that they were nothing compared to her. She was unapproachable because she was perfect, perfect because she was unapproachable.

Reagan glared at Alan who flinched away. When everyone thought Alan was dead for sure, Reagan did something unexpected. She flicked her hand and immediately the stains on her shirt disappeared as if it weren't there and her hair got fixed back to its perfect state. Then she sat done and continued stirring her potion like nothing happened.

This raised even more questions. Was that wandless magic? How did she know how to do that? It would take a lot more time until Reagan felt comfortable enough to share her past and would need a lot more information before Teddy could figure out who, or what Reagan is.

But one thing Teddy knew for sure.

Reagan is anything but ordinary.

So how do you like that? I'm just jotting done ideas as I write, completely ignore the twenty page science notes (must be written in paragraph form) that is due tomorrow. Please call me the master of procrastination. From now on, it will be the events occurring in the sixth year of Teddy and Reagan's life. And no, I do not ship them. The love is platonic. There will be a lot more about that later on. It will be written in normal format and not in this(this is what I call remembering the past in one character POV format) format.

I do not update unless there's at least one review/favorite/follow. Just a warning ;)
