Hello my guys! so I'm just sat at home posting this with an evil grin and a cackle because this should give people some idea of who the traitor is going to be, and I hope people are cool with it. I think most people will have at least heard of them? I've mostly read fics with them in to be honest but they are a cannon character who was a traitor so I mean, enjoy.
Also, Percy and Luke are just being badass here let's be honest they'd totally enjoy showing off.

Percy and Annabeth headed back to Cabin eleven, arms loaded up with sleeping bags and toiletries.

When they made their way inside Luke was happily sat chatting with several of the younger Campers, grinning widely-and Percy couldn't help but think that he looked at home-but that did make sense.

She knew that if there was one thing Luke loved it was being a big brother, he loved having people to take care of, people who depended on him-and she could see now how easily he'd slip into that role here if he was given the chance.

"Hey guys." Percy called easily as she stepped over someones sleeping bag and made her way to the beds, "We come bearing sleeping bags."

"What took you so long?" Travis frowned, "You were gone for ages."

"Clarisse." Annabeth's lips twitched at the memories, "She tried to do her stupid initiation ceremony on Percy and it backfired-on that note I want to team up with Hermes Cabin for Capture the Flag on Friday."

"Wait, what?" Connor raised an eyebrow, "How did it backfire-and that's fine with us we like working with you but why?"

"Percy." Luke sighed, giving her a look, "What did you do?"

"I'm wounded that you'd think I did anything Luke-" Percy pressed her hand over her heart as Luke's brothers glanced between them both with confused expressions.

"Annabeth, what's the initiation ceremony?"

She likes shoving newbies heads down the really horrible dirty toilets." and actually now Percy kind of wished she didn't have to hide who she was because that would have been so much fun-she'd have drenched the Ares campers with toilet water.

Luke's eyes narrowed-he knew how Percy's mind worked and he gave her a warning look "Persephone Alethea-"

"Hey! Don't you full name me!" Percy yelped the words, "I didn't do anything that bad, we didn't even get to the toilets I just took all four of 'em on. Honestly I was pretty lucky they didn't expect me to be able to hold my own."

"It was pretty awesome to watch." Annabeth admitted, "Though I think you've made enemies for life of the Ares cabin."

"You took on four Ares campers at once." that was the boy who had spoken before, who'd asked how she was unclaimed if her brother was a son of Hermes, he'd raised an eyebrow and was looking at her in disbelief. "How?"

"Uh," Percy flushed, "I can fight?"

"She's been learning since she was five apparently." Annabeth added, "It was amazing to watch, seeing her knock Clarisse down was just... just amazing."

"How good are you?" Travis leaned forward- "And if she's been training since she was five-"

"I started training at nine." Luke shrugged, "She started two years later as soon as she was old enough to ask to."

"Okay but can you use swords?" Connor piped up.

Percy and Luke exchanged grins and they both pulled out their swords, Percy uncapping Riptide and Luke pressing the pearl of Episkopos.

There were several gasps and Percy gave a mock bow."

"Is that the sword you used to kill the Minotaur?" that was green eyes again, and Percy nodded.

"Yep."

"We have to see how good you are." that was a younger boy-maybe eight years old, and one look told her he was one of
Luke's little brothers, he had the same eyes, the same grin, and Luke hesitated.

"What do you think sis?"

"I think I'm gonna kick your ass."

Luke smirked at that, "Well I suppose there's a first time for everything-"

"Oh it is so on. Travis, Connor where do we go?"

"The arena." Travis was on his feet quickly, "Let's go."

And with that pretty much the entirety of the Hermes cabin plus Annabeth were making their way to the Sword fighting Arena, which turned out to be a large amphitheatre near the edge of the forest, there were straw dummies to the side, and a large arena in which they could do the actual fighting.

"You guys do realize it's time for dinner soon-"

"Don't be boring Annibeth."

"Yeah Wise Girl." Percy shot the girl a grin, "Don't be boring."

She watched as everyone moved to the seats, with Annabeth, Connor and Travis lingering at the edges of the arena.

Percy then focused her attention on Luke, who smirked back at her, "Wanna give up now little sis?"

"Not a chance." Percy twirled Riptide, "This time I have a blade that I can actually work with." she pointed out."

"You've used Episkopos before."

"Yeah, but that's your sword it's never felt right for me. This one though..." she trailed off, grinning as she tilted her head,

"First blood?"

"That's fine with me." neither of them would hurt one another much-but little cuts were hardly too bad-on one memorable occasion Percy had accidentally stabbed Luke in the foot when trying to use Episkopos.

"On three?" Percy raised an eyebrow, and Luke nodded.

"One... two... three." and they both sprung into action as the word left Percy's lips.

The problem was they knew each other too well, they'd been training together, learning together for seven years, Percy knew the way Luke fought better than she knew how she thought, and he knew her style too-though Percy did tend to be the more unpredictable out of the two of them.

He was bigger, had the longer reach, but Percy was small and fast, nimble too, she didn't stay in one spot for long-she always said it was because she was like the sea itself, always moving.

Luke lunged, sword swinging and Percy ducked under the swing, twisting and sliding under his arm behind him, swinging Riptide-but Luke was already twisting himself and their blades met, Lukes blocking her slash, his foot lashing out, and Percy was leaping backwards to avoid being caught with the trick she'd used on Clarisse-though she didn't stay back for long, whirling into motion, her blade parrying Luke's thrust.

It was a game to them, a dance-they'd done it so many times before, and they were both grinning as they moved.

There was some competition between them, but it had never been nasty-they'd never been worried about who was the best-and honestly they both knew that out of the two of them Percy was the most powerful. Within a few years when she'd grown that but more Luke's size advantage would be pretty much gone-for now Percy was generally that bit better than her with a blade, though it wasn't much and during their spars there had been several close calls.

If Percy used her powers though, well if she did that then they both knew who would be the winner.

Their teasing was always friendly, their fights were never nasty, but they were hard, and they could go on for a long time-as this one was doing, the sounds of blades clashing and panting filling the arena.

Percy and Luke were both struggling, both panting and sweating, but neither of them let up-they were both too stubborn for that, but still, Percy couldn't help but long for cool water to soothe her dry throat and refresh her-of course if she had that Luke would call it cheating-he always did.

She wasn't sure how long the fight had been going on when she spotted the opening-Luke was just as tired as she was-maybe more, since she'd had a glass of nectar not so long ago, and she was sure he hadn't slept much while waiting for her to wake.

They were both exhausted, and she could see, he was holding his arm just a bit lower than he should be-it wasn't much, just an inch or so, but she could take advantage, get him to lower his guard that bit more so she could get in and get first blood.
She feinted, lowering her shoulder just so, leaning forward slightly, trying to make it look as if she was trying to conceal what she was doing rather than displaying it for him to see.

And the feint worked, Luke lowered his blade, ready to parry her next thrust, and Percy was rushing forward, slashing her older brothers arm, not hard, but she sliced through his shirt, and she heard his shocked gasp as his free hand flew up and pressed over his arm.

When it came away there was blood. Only a bit, it was barely even a scratch but it was there.

There was a moment of stunned silence as they stared at each other, Percy's mouth dropping open.

Then Luke was surging forward, dropping his sword-and Percy dropped her blade too as a pair of warm strong arms wrapped around her and picked her up, swinging her around.

"You did it!" he was laughing brilliantly, "By the Gods Sephie you did it! You got first blood."

"I beat you!" Percy nearly shrieked the words, "I actually beat you in a fight."

"You beat me!"

"I beat you!" she could hear the cheering from the rest of the Cabin, and then Annabeth, Travis and Connor were there, all three of them grinning.

"That was amazing." Travis blurted out, "Gods you two were something else!"

"Oh you are so working with my Cabin for Capture the flag." Annabeth declared, "That was an amazing fight you two."

"You should talk with Chiron." Connor clapped Luke's shoulder "We could do with you helping younger campers learn how not to stab themselves every five seconds. And you Percy."

"I can't believe I won." Percy admitted, "I... that's the first time I've won."

"Knew you could do it." Luke slung an arm over her shoulder, "Think my wound will scar?"

"Luke!" Percy shoved him with a laugh, "Don't be a dick, mom would literally kill me."

And now that the fight was over the rest of the Hermes Cabin were moving to join the excited chatter.

It felt right, it felt good. Back at home, as much as Percy loved it, she knew she was a weirdo who didn't really fit in-oh her mom and Luke made it worth it but she was aware that most girls her age didn't worry about monsters or fighting for her life, but everyone here? They were like her, they understood-and they were welcoming her and Luke with open arms.

It was Annabeth's prompting that reminded everyone that they were late for dinner-by almost half an hour, and holy Hades but had she and Luke been fighting for half an hour? Clearly so but it was hard to believe.

Luke was dragged to the front of the group as they made their way out of the arena, Travis and Connor babbling at him about how he needed to start giving lessons.

Percy had lingered back to talk to Annabeth, but the blonde girl had needed to rush on ahead after a moment so she could join her siblings at their table.

Percy wasn't alone for long though, perhaps a minute after Annabeth sprinted off a voice came from just behind her. "Gotta say you're a lot better than you look, no offense." and Percy turned her head. It was the boy from earlier, green eyes as Percy had mentally dubbed him.

"None taken." Percy ran her fingers through her long hair, pushing it out of her sweat slicked face. "I know I don't necessarily look like much of a fighter." she was short, skinny looking-oh she had muscles, but they weren't bulky, she was slim and petite as her mom had always put it.

She liked that though, it made people like the Ares campers underestimate her.

"You might not look like one but you're a hell of a fighter." the boy commented, and Percy took a closer look-he was taller than her, though she had to admit that that wasn't exactly difficult given the fact that she was pretty short, he was lanky too she noticed, and he had freckles covering his cheeks.

"Thanks." Percy gave a small shrug, "What can I say, I do my best." she gave a mock bow "And I really should be with how long I've been training. Luke and I usually spend an hour or so a day practicing."

"So what else can you do?" the boy tilted his head, "Anything that'll help give away your parentage"

"Not really." Percy lied with practiced ease-growing up with a klepto son of Hermes meant that she'd gotten a lot of practise at that over the years, no matter how much her mom disapproved of it. "I'm sure it'll come. I'm not in any rush."

"Most kids are. Hermes Cabin is pretty cool but it's way too crowded, everyone in there who's unclaimed is hoping they'll get claimed and get to move to a different Cabin."

"It seems nice to me." Percy paused "Though... I guess I get it. I don't get why they don't have an undetermined Cabin or a Cabin for the kids of minor Gods and Goddesses-"

"Now that is a good question." the boy gave her a small smile. "I'd like it, I know that much."

"You're not a Hermes kid then?"

"Nope. I'm Alabaster Torrington, son of Hecate."
