When they arrived at the airport check-in desk, Adrien was surprised to find that he could read the clerk's name tag.

"Good morn- I mean evening," said the Aurea the check-in clerk, cheerfully. "Welcome to Delta Airlines. The weather sure is beautiful for flying with a strong westerly wind-"

"I'd like two return flights for Nathalie and Hanno to Mount Olympus," interrupted Nathalie, handing over the three passports, "and a one way ticket for Adrien."

"And what were the dates for the return flights?"

"Tomorrow."

"Easy-breezy," Aurea said, smiling. She typed a few things into her computer while chatting animatedly about how they had to visit the new fountain building designed by some demigod.

"Aren't you staying?" Adrien asked. Even if it was Nathalie and The Gorilla, it would have been good to have some friendly faces at Camp Half-Blood.

"We have work to do in Paris," she told him. "Our job is to find more offspring of the gods and goddesses like you and bring them to safety."

Adrien wondered which Greek god was his father. It was probably Hades, god of death.

The clerk suddenly stopped in the middle of recommending that they go and try the honey cakes at eateries by Hestia's hearth and frowned. "Uh, unfortunately, all borders of Mount are still closed. I thought it would've been fine by now…"

"How long has it been like this?"

"For about a month," she said sheepishly.

"Surely you should've known this." Nathalie rubbed her temples and muttered "airhead aura" under her breath so low that Adrien barely heard it. "A flight to New York then. How much will that be?"

The clerk cheered up. "Any checked in luggage?"

"No, carry on only."

"Just a moment."

While Aurea continued to chatter away and book the tickets, Adrien asked Nathalie a question. "Isn't Mount Olympus in Greece?"

"The entrance is now in the Empire State Building, New York. It would be safer to fly there than a commercial airport, but I guess we'll have no other choice. We can still get someone to pick us up and take us to Camp Half-Blood from there."

"The tickets will cost five dekadrachm, two tetradrach- oh, and a triobol," announced Aurea.

Adrien didn't know how expensive that was, but judging from the twitch in Nathalie's eyebrow, that was expensive.

Nathalie handed her a bronze credit card over the counter. "Credit and sign."

"Sure." The clerk then took out a laminated sheet with a list of prohibited items. The list included aerosols, liquids and weapons in their activated form. "While I make the transaction, please review the list to ensure that you are not carrying any of these items."

Nathalie impatiently tapped the counter. "Is there an Iris call booth somewhere?" she asked.

The clerk waved her arms towards her left. "There is, around the corner. However please be advised that Iris calls to Olympian gods, goddesses and other residents of Mount Olympus cannot be connected."

Nathalie narrowed her eyes. "I see. In that case, can you arrange a car rental for one day?"

"Absolutely, and I assume with the full security features as well?"

"Yes."

"That will cost another didrachm, please."

"Just charge it to the card. Is there other news that we should be aware of?"

"Nothing," she said, handed them the ticket. "Here are your tick-oh but wait! I remember! Percy Jackson has been missing for a few days now. Word on the air is that things are really bad in Mount Olympus."

"You don't say."

Adrien wondered who this Percy Jackson was.

"Is that all?" Aurea said with a bright smile.

"That is all."

"In that case, please remember to be at the boarding gate at the time written on the ticket and have a safe flight!"

Dear Diary,

A new day, a new demigod. This one arrived just as lunch was being packed away. We had spinach and salmon quiche which is one of my favourite foods they serve at the camp, but even that wasn't able to remove the sting of just losing the capture the flag game because the Hephaestus Cabin's automatons exploded. The dragon might be gone from the woods but it doesn't mean that the curse had been lifted. Our team also had the Ares kids who were very angry and annoyed. The Aphrodite kids who on the other side were being annoying, laughing at us. I can't believe we lost! We were winning too…

But, there's no point dwelling on that too much. We will win next time for sure!

What was I writing about? Oh, that's right! The new demigod!

His name is Adrien Agreste. Yes – Agreste, as in he is the son of the muse of Gabriel, my favourite designer. He's even been in a few of his fashion ad campaigns. I thought that he looked familiar...

You'd think that with his golden hair like Jason and his model physique that he would be another child of Aphrodite's, but it turns out that he's Apollo's like Nino. A ray of sunshine followed him around like a stage spotlight for an hour.

I hope that he was wearing sunscreen. Or do Apollo's kids not get sunburnt?

Now that I think about it, Adrien looks a lot like Will Solace, the head counsellor of Apollo, but with tidier hair and green eyes brighter than Percy's.

What? It's really hard not to notice that.

Anyways, according to Alya, who apparently was friends with him in Paris he's really nice. She said that was worried about him when she left for Camp Half-Blood because he didn't really seem to have any other friends.

However, when we went up to welcome him to the camp, guess who pushed me out of the way to greet him with a hug.

"Hey, Chloe."

Yeah, that's what he said.

Alya claims that he's her friend and that she trusts him, but I don't know about that. He didn't even greet her and he's clearly really good friends with Chloe, who's not a character you can trust. I don't think you should trust anyone associated with Chloe.

For the rest of the day she was latched onto him and made disgusting cooing sounds like a pigeon while he walked around the camp signing autographs.

Anyways, I have to sleep. It's getting late. Who knows what other demigod will arrive tomorrow.

"We have to sit with our cabins for dinner, but we'll talk again later," said Chloe Bourgeois.

He was surprised to see her here. He thought that she was on a high school exchange.

She blew Adrien a kiss and went to sit down at the Aphrodite Cabin's table. In all honesty, all he really wanted to do was eat and sleep. His last meal was breakfast on the plane and when he arrived at Camp-Half Blood, they had just finished lunch. Not to mention, he was jetlagged.

Soon after he arrived he was claimed by Apollo and then he was shown around the camp by Chloe.

She insisted on clinging on him, which made Adrien nervous. He didn't want her to get infected with whatever he gave to Gabriel.

He wondered what had happened to Gabriel. Even though he had controlled his memories, Adrien hoped that he didn't kill him. But Gabriel looked really ill with whatever he did to him. What if he did kill him? Some offspring of the god of healing he was turning out to be.

However, Chloe didn't seem affected by anything as she gave him the tour.

For the most part, the place looked just as he would've imagined how an American summer camp would have looked. It was in the woods, there was a giant lake, there was a place for a campfire, everyone slept in cabins, there were horses and there was a rock climbing wall. Except this rock-climbing wall spewed lava, and the horses were had wings and the Cabins were personalised to represent a Greek God.

The Apollo Cabin looked fairly ordinary compared to the some of the other ones such as the Ares one which had barbed wired on the roof and boar's head above the door. However, in the sunlight the Apollo Cabin gleamed like solid gold.

Adrien wasn't introduced to any of the other Apollo kids on the tour, and he wished he was. He felt nervous at the thought of sitting down on a table with kids that he didn't know, even though they were supposed to be his siblings. From what he remembered, he didn't spend that much time around other kids.

A part of him wished that Nathalie and The Gorilla didn't have to leave so soon after dropping him off at the camp. But they had to go help the other kids that didn't know that they were a demigod. And if he wanted to help find his mother, he would have to complete his training. They promised to message him if they got word about his mother.

Adrien waved in reply to Chloe, and sat down on the Apollo table. He put on a smile and waved to the boy next to him. "Hey, Adrien," he said.

The boy just replied coolly, "You're friends with Chloe then, huh?"

Adrien looked over at her and cringed. She was yelling at some other girl.

"I've known Chloe since I was a little kid," he admitted. He rubbed the back of his head. "I know she's not perfect, but she's like my only friend."

At this the boy's expression softened. "I'm Nino," he said, offering a hand, "and it's time for you to make some new friends dude, even more than a friend, a bro."

Adrien, hesitated slightly, and then took the hand.

"So I hear that you're from Paris," said Nino. He held up a dish. "By the way, did you want some casserole?"

"Yes please, I'm starving. And, yeah," he said taking some of the food, "I lived in Paris, at least when I wasn't travelling. Where are you from?"

"Paris, as well."

"Really?"

"Yeah, I came over here a few months ago with Chloe and Marinette who is sitting at the Tyche Cabin's table over there. Ah, she's talking with Alya from the Hermes Cabin who you might know. She mentioned that she knew you back in Paris."

"Yeah." A part of him wanted to say hi to her, but he didn't really know what to say. "I think so."

"Think so?"

Adrien finished chewing his food before speaking again. "I'm having trouble with my memory."

"You're a little young for memory loss, but Alya did say something about that."

"Apparently it's Mist."

Nino rested his chin on his palm. "Any nausea?"

Adrien shook his head.

"Pain?"

"Not unless I try to remember something that I don't."

"That's how I felt all the time in school," laughed Nino. "And you don't do drugs or alcohol?"

"No." Adrien added after a moment, "occasionally a bit of champagne at dinner."

The other boy stroked his chin. "Do take any medication?"

"Nope."

"It's probably Mist," concluded Nino. "It will most likely wear off in a day. But probably ask Will Solace once he's finished treating all those casualties from this morning's capture the flag game. Man, that was absolute carnage… Anyways, Will is much better at the healing than I am. My talents lie more in the music domain. Hey, do you play any instrument?"

"I can play the piano."

Nino smiled broadly. "Awesome! We could use someone on the keyboard at the campfire session. What do you say?"

"Sure," said Adrien, returning the smile.

Dear Diary,

Alya and Nino both claimed that Adrien is a good person, but I knew that a friend of Chloe's couldn't be trusted.

We had the Trials of Strength today in the arena and during the tandem tug of war competition he and Nino joined as a team. They were against two members from the Ares cabin who were trash talking and throwing Yo-Mama jokes as usual. Then the Ares cabin started violently coughing and struggling to breathe. It looked as if Adrien was doing that with his powers because Nino approached Adrien but then he too was inflicted with whatever it was.

You're not supposed to use your powers in a Trial of Strength! And what kind of child of Apollo inflicts a disease instead of healing them, especially to a friend? If he really was Nino's friend, then he would stop and help them, but instead he ran away, unable to face up to his mistakes.

Alya thinks that it wasn't intentional but I said it before and I'll say it again wouldn't put anything past someone who's a friend of Chloe's.

Will Solace rushed to sick campers and immediately sent them to the infirmary. They haven't been released yet so it must be serious.

I'm just so angry, I -

Ah! I completely forgot to write about the arrow, the lyre and the honey pot incident!

I'll write about it next time. I can't process anything else today.

Author's Notes:

Hello!

One thing that I find both useful and tricky to deal with are all the details that are in Miraculous Ladybug and the Heroes of Olympus series. It helps make the characters more consistent with the canon (and fill out the word count) but sometimes it means that I have to rewrite some scenes.

In the original draft, I had Apollo pick up Adrien from Paris in his Maserati of fire, and the part of the conversation with Nino where he was trying to diagnose Adrien was originally supposed to be in the car ride.

But then I remembered that Zeus had closed Olympus about a month before Jason arrived at camp half blood, so out with Apollo, in with Nathalie. There was another fun chapter I had drafted up that included Apollo that had to be taken out too. Luckily it didn't actually affect the plot. Maybe I can recycle parts of it elsewhere.

Please let me know if something doesn't make sense to you. And thank you for reading!
