Notes: This is probably not complete and I am considering extending it and making an actual story out of this. But this fic really explores the idea of Jason having to chose between Piper and Reyna, who I have tried to make complete opposites in this story.

Piper really hated these things.

Not only was she expected to look good, but she was expected to be nice to her father's co-workers too.

And that was the thing that she hated more than anything, ranking highest on "Piper's list of things she hates" above "Climbing the lava wall at camp"

But this afternoon she was about to be introduced to her dad's co-worker who was her age, because apparently people get along based on age alone. So with her dress in one hand and sandals in the other, she knocked on the hotel room door.

"Hold on, Hold on!" A voice shouted from inside the room, then a crash and some cursing in English and a language that Piper did not recognise, and the door was flung open to reveal a tall blonde girl wearing only a small pink towel. Tristan looked away pointedly and mumbled something about the two of them having fun and him seeing them later because he had lots to do, before pushing Piper into the room.

The blonde girl blinked and looked over at Piper. "It's Piper, right?" Piper nodded. "I'm just gonna get back in the shower. Trust your dad to show up when I'm showering right?" She giggled "I'll be like 10 minutes, 15 tops." Piper nodded again, slightly taken aback by the chatty almost naked girl who was stood in front of her.

The girl skipped over to what Piper assumed was the bathroom, jumping over piles of shoes and a suitcase, strategically pulling her towel down to cover herself.

Piper just shook her head and wondered what in Tartarus had just happened.

Looking around the room it was apparent that the girl was not a fan of organisation, with paper and sheet music strewn across the room on every surface, a guitar carelessly thrown onto the bed and some speakers with an iPod hidden underneath a pair of long black socks.

The shower was still running when Piper risked looking at one of the sheets of paper on the bed. Her eyes widened as she scanned the page, looking through each limerick. She paled and threw the sheet as far away from where she was sitting as she could before blushing furiously. At that moment the bathroom door opened and the girl whirled back into the room now wearing a short fluffy white bathrobe and the pink towel around her hair. She noticed Piper's face and grinned.

"Not a fan of erotic poetry Piper?" She winked and Piper blushed again.

"I just wasn't... expecting that." The girl smiled, but then frowned.

"Where are my manners? I haven't even introduced myself properly have I?" She stretched her right arm out and her sleeve fell back. Piper glanced down at her arm and noticed the eight black lines burned into her skin.

"One for every year spent in the camp itself" Jason's voice echoed in her head as Piper stretched her own hand out and shook at the girl continued speaking.

"Reyna's the name, and don't worry. I would NEVER bone your dad, even though I know that that is what all of the tabloids are saying. I prefer tall, blonde muscular heroic types rather than the strong silent type like your dad if you get me?" She giggled and winked again before releasing Piper's hand and moving to pick the socks off of the speakers. Piper sat down on the edge of the bed.

"Cool tattoo." Reyna stalled for a moment, a look of pain crossing her features before realising that Piper was watching her, and she smiled again.

"I have several, I just don't show them off." She giggled again, but this time it felt fake. Forced, even. "Don't ever get a tattoo. Hurts like a bitch. Plus you have amazing skin. Has anyone ever told you how amazing that colour of skin is?" Piper shook her head. "Oh, that's a shame because it is awesome."

Piper was taken aback by the sudden change of topic, and couldn't help but feel that there was something important that this girl wasn't telling her about these tattoos of hers.

"Erm, thanks. That's really nice of you." Reyna smiled in a way that reminded Piper of the Apollo kids back at camp.

"Are you coming to the premiere?" Reyna asked as she bobbed to the floor, crawling around on her hands and knees looking for something on the floor.

"Yeah, I brought my dress and shoes 'cause my dad wanted you to look at them." Reyna sat up, with one red, platform heel in her hand.

"Awesome. Wap it out." She went back to crawling around on the floor as Piper unfolded the long dress that she had picked out herself in spite of Lacy's screams of horror and protest that Piper had to wear something short or even worse... Strapless. Piper tried to tell herself that the dress didn't look bad, but she couldn't kid herself. The dress was pretty awful and the only reason that she had chosen it in the first place was so that no one would look at her when she arrived with her dad. It was long, read, orange and navy blue with a silver lining around what little cleavage she had to hide it. Needless to say, when she had bought it she had hidden it far away from Lacy.

Reyna looked up and gasped in horror.

"You don't like it?" Piper asked.

"Sweetie. I cannot morally let you wear that dress." Reyna said, standing, looking Piper over. "That dress needs BURNING and it's ashes thrown into the sea. Then, when the ashes are in the sea they need to be collected up again in a jar and displayed on your mantelpiece as a reminder that you should never, EVER wear a dress like this with a body like yours, so in other words, I HATE it."

"I don't have anything else to wear" Piper protested, hoping to inch away from Reyna's stare. Reyna seemed to consider this for a moment before rushing to her suitcases, throwing dresses over her head to land on the bed. She looked up when Piper made no movement.

"You gonna stand there all day or are you gonna try these on?" Piper was gobsmacked.

"I can't!" She protested again. Reyna straightened up and put her hands on her hips.

"Yes you can. I insist that you let me dress you. I even have a team of stylists who would be willing to do your hair, makeup and whatever altercations you need on the dress that we choose out for you."

"But we're so different!" Piper's argument was weak, and she knew that she wasn't going to win this one, but she still pointed up and down Reyna's tall, curvy figure and then down at her own medium height and more athletic build.

"My stylists are pretty damn awesome. Now, go and wash those braids out of your hair and I will pick your out a KILLER outfit!" Reyna pulled Piper across the room and into the bathroom, closing the door behind her.
