This Wasn't Part Of The Tour

Jason had been begging Percy to take him around New York City, ever since the Giant War when he got his first glimpse of the Big Apple when he visited Olympus. The son of Poseidon finally relented, and took his friend on an aerial tour of New York city courtesy of Black Jack, and Tempest touring services.

Jason was really excited, as he acted like a fan girl when Percy pointed out famous spots like the Chrysler Building, and the new Freedom tower that took the title of tallest skyscraper in New York just recently (1776 ft). They landed in Central Park, and Percy showed him around there before walking to Times Square.

"What's so special about Times square? It's just advertising, shopping, and creeps in costume." Jason said moving away from a guy dressed up like Spiderman.

"Well a lot of people come here simply because it's Times Square, and they like to get dazzled by all the LCD screens." Percy answered with a shrug. A little while later they sat down on the patio of a burger joint a couple of blocks away. The sounds of car horns, construction, and people filled the air as the heroes devoured their burgers.

"Didn't we see a sign earlier that said if you honked you'd he fined $500." Jason asked in annoyance as a car behind them repeatedly honked. Percy didn't seem bothered at all, as he sipped his soda.

"Yeah there's a law that says you can't, but the police hardly enforce it. You get used to it." He said dismissively. Jason frowned and stared at the traffic annoyed. Percy smirked at him; Jason was such a stickler when it came to rule abiding that it truly was a wonder how the two of them managed to be friends. Percy followed Jason's gaze into the traffic, and froze when he saw a pair of gold eyes and a cocky smile looking back at him. Jason noticed Percy's change in demeanor, and put his hand on the pommel of his sword (The mist made his scabbard look like a fanny pack which Percy still made fun of him for).

"Where is it?" Jason asked with narrowed eyes scanning the area, already assuming that there was a monster nearby. Percy looked back at Jason with an annoyed look on his face.

"Nothing, the mist is just playing tricks with me again." Percy lied suddenly interested in his fries.

Jason frowned dissatisfied with that answer, but he knew better than to bug Percy. He remembered when he and Annabeth first came out of Tartarus and how they refused to talk about their experiences. Percy would give him an angry, scary, animal-like look if he even mentioned the place or anything he didn't want to talk about. The hero of Olympus was nearly back to his old self again, but Jason didn't want to test him.

Jason kept staring in the direction Percy had looked in. He picked out a tall, muscular, blonde guy walking toward them. The strange thing about him was his eyes; they were gold like Hazel's.

Percy looked back, and stood up.

"Jason there's a lot more I need to show you before we run out of daylight so lets go." Percy said urgently already starting to walk away. Just then gold-eyes walked up to them.

"What's up Jackson, who's your little friend?" Jace asked sizing up Jason with a smirk on his face. Percy face-palmed and Jason narrowed his eyes. Who was this guy calling little? Sure, Jace was an inch or so taller, but Percy was the shortest one here not him!

"Excuse me, but who are you?" Jason asked straightening up to his full height and puffing out his chest in the basic intimidation tactics Lupa taught him. Jace just smiled wider at Jason's annoyance.

"Jace Wayland." Jace answered thrusting out his hand.

"Jason" Jason replied accepting the shake still watching Jace with hostile eyes. Jace was wearing a black leather jacket over a white v-neck shirt, jeans, and biker's boots. He had strange black tattoos on his hands and neck. If Piper thought Percy was a trouble maker, this guy was the epitome of bad boy.

"Like what you see?" Jace asked with a smirk. Jason jumped.

"Wh-what? I-I..." Whatever Jason was going to sputter out Percy saved him from making a reply, by stepping between them.

"Jace this is a bad time, and this goes against our deal." Percy said glaring at Jason. Jace just stepped aside, and looked toward Jason again.

"So who's your godly parent?" He asked looking down on Jason. Before Percy could intervene again Jason began his speech.

"I'm the son of Jupiter and Praetor of Legion fulminata and New Rome." Jason announced proudly his eyes flickering with electricity for extra effect. Jace snapped his fingers.

"Ah your that kid that Jackson traded places with." Jace said. Jason didn't like being called kid either.

"What in Pluto are you?" Jason growled sparks lighting up his fingertips looking from Jace to Percy. He was about to lose his cool completely. No one had ever dared to show such insolence toward him, except for maybe the other big three kids. Percy stepped in between them again. He'd been shocked enough times from the Grace siblings, he hardly felt it any more.

"Jason calm down Jace's a jerk to everyone. Besides he's leaving." Percy glared at the shadowhunter. Jace put his hands up like he was innocent.

"Hey I don't get to meet your friends? That's not fair I was just starting to have fun with Jupiter Junior over here." Jason sighed and crossed his arms trying to get a grip on his anger.

"You still haven't answered my question pretty boy." Jason spat. Percy gave him a warning look that Jason ignored.

"I'm not part of your mythology world. I fight my own set of demons that like to harm humanity." Jace said. Jason just looked at the shadowhunter like he suddenly grew an extra head.

The son of Jupiter looked at Percy as if to say "really?" Percy just shrugged, like he wanted no part in this.

"So what are you?" Jason asked as if he asked "What planet are you from?" Jace just flashed his dazzling smile.

"Wouldn't you like to know gladiator boy unfortunately that information is classified." Jace said. Jason turned on Percy frustrated.

"Do you know what this guy is?" Jason demanded. Percy scowled at Jace.

"Well since you already made your presence known, and he already knows to much just tell him. Jason can keep a secret." Percy told the shadow hunter before glaring pointedly at Jason at the end.

"Well alright I'll explain myself only because Sparky here is about to cause a power surge in the next two blocks." Jace shrugged with his ever-present smile.

When Jace was done explaining Jason was completely dumbfounded.

"Really Percy, you knew about all this and didn't tell anyone? You're as bad as Nico with keeping important secrets from everyone!" Jason growled.

"I kept Jace's world a secret for the same reason Nico kept the camps a secret from each other, it was for your own good." Percy said defensively.

"What about us? Did you tell this nephfreak..." Jason began

"Nephilim" Jace corrected.

"Whatever, did you tell this guy everything about us, our secrets, weaknesses...?" Jason listed flabbergasted.

"Don't be ridiculous, Jace and the rest of his people don't know where the camps or Olympus is. As far as I know they don't know anything that could be used against us." Percy assured the Praetor waving his accusations aside.

Jace nodded, "It's true, Percy won't tell me anything important. Besides I'm not interested in fighting a bunch of kids." He said.

"Jason it's important that you keep this a secret we could be putting our two worlds in danger if the Gods, or the Clave find out." Percy implored. Jason was quiet for a moment looking out into the busy sidewalks, as he gathered his thoughts.

"Alright I'll pretend like I never met you Jace, but Percy be smart about this." Jason relented. Percy frowned, and tried not to feel to offended by that last comment.

"So, Jace want to spar against a real gladiator?" Jason challenged. Jason was fed up with how this guy wasn't taking him seriously, and wanted a chance to put him in his place. Jace grinned, his eyes glinting with the thought of a challenge.

"I've sparred with beach bum over here enough times, that I know your demigod tricks, and moves." Jace said confidently.

"Percy's Greek I'm Roman there is a difference in fighting style." Jason insisted. Jace looked to Percy who nodded.

"It's true, in my first war games at Camp Jupiter the Romans had no idea how to fight back against me." Percy said smugly. Jason glared at him, and Percy just grinned back.

"Alright, I accept your challenge Jason son of Jupiter." Jace said extending his hand to seal the deal. Jason accepted the shake with a grin as he gave the shadow hunter a little shock out of spite.

"This ought to be good." Percy said anticipating the battle of the blondes.

A/N- Thank you Owlcat92 for the idea for this one-shot, and all the other ideas you listed that was great! Rick never specified what Jason's new sword looks like to mortals, so I just made up that fanny pack thing just to put some humor in ;)
