i. back and forth from new york (sneaking in your bed)
Percy Jackson has become a light sleeper.
He didn’t think it was even possible to be yanked from sleep so harshly, but finds himself jolting awake whenever the kid nexts to him so much as turns over in his sleep.
He chalks the nerves up to his new… situation. If finding out your father is Poseidon and watching your mother turn into dust Avengers: Infinity War style could be called that.
This is also the first time he’s slept around so many people, so he thinks he’s just on edge. It’s not like he was ever close enough with anyone to warrant a sleepover before.
He shuts his eyes, willing himself to go back to sleep.
Until he can’t.
There’s tossing and turning from across the room, and then a muffled noise.
Someone’s sleep talking.
Percy groans in frustration before realizing he’s being too loud. Thankfully, the kid next to him seems to be desensitized to random nighttime grumblings. Which is understandable, seeing as there’s an entire classroom of other children around them.
Percy takes his pillow that’s barely thicker than his forearm and clamps it firmly over his ears. He counts sheep. He imagines them jumping over fences when that doesn’t work. And then he imagines them as Chiron when that doesn’t work either.
The grumbling doesn’t stop. But as Percy peels the pillow from his ears, he realizes that the measly fabric was able to muffle something.
The crying.
Percy squints across the room, his eyes well adjusted to the darkness by now. He can see the Thrasher now, tossing in their sheets as quiet sobs leave their mouth.
Heard what happened to you on the hill. And I just…
He can make out a dark mop of hair.
Wanted to say I’m really sorry.
Tall limbs and a red cotton shirt.
I know what you’re going through, believe me. I’m—
Luke.
That’s Luke’s bed, Percy realizes. The heroic and brave and wise boy who introduced him to camp is crying thirty feet away from him, and he has no idea what to do.
A twig snaps from outside, and Percy jolts upright. Ah, of course, how could he have forgotten about the second reason he’s feeling so twitchy? Apparently all of those mythological monsters he’d learned about are real, too. Because someone out there is plotting against him.
The memory of rain soaked clothes and the feeling of a sharp horn under his hands has Percy fumbling for his pocket, sweaty fingers closing around Riptide.
Should he wake Luke? Surely he would know what to do. But the idea sounded ridiculous. The camp was safe, it had to be. Grover had said it himself. It wasn’t possible for anything to get past that old tree on the hill.
But rational thinking was beginning to look less rational since he was alone with whatever creature was outside. Something was definitely on the other side of the wooden walls, and it was just Percy and his stupid pen against whatever monster is making its way nearer.
Whatever it is is nearly silent, making its way around with soft footfalls and quiet steps. But the wood of the patio outside creaks under their weight, and Percy thumbs the cap of his pen nervously.
The doorknob twitches, and a cold chill goes down Percy’s spine when he realizes that the door isn’t locked. The door creaks open without protest.
It’s a person.
Much less scary than previously anticipated, but a potential threat nonetheless. Percy watches in awe as the hooded figure carefully steps over the floorboard that he nearly tripped over about thirty times already, dodging limbs hanging out of beds and sleeping bags. A perfectly trained ninja in the night.
Percy pushes himself up using a forearm, concealing Riptide in his sleeve.
“Who are you?” he croaks, voice choppy from disuse. “I have a weapon, so don’t try anything.”
He winces at the way it's much less intimidating than he hoped.
The figure whips around, their hood slipping down to reveal their features. Moonlight streaming in through a window illuminates your face.
Oh. It’s you.
Luke had introduced you to him earlier in the day, and he can’t remember much about you. But he remembers the easy way Luke had been around you, a closeness that Percy hadn’t seen before.
—
You were lingering around the forge, and had gotten a front row seat to Percy nearly setting someone on fire.
“Luke, why are you giving hot tools to twelve year olds?” you’d asked as Percy shed his goggles and gloves frustratedly.
The two boys turned around to find you standing right behind them.
Percy flinched away, and Luke laughed at the face he was making. “Percy, this is—”
“Luke’s best friend,” you had proclaimed, slotting yourself against his side. Percy was on the fence with what he thought about Ares kids, but the difference between you and Clarisse could not be more clear. You were all smiles as you reached down to ruffle Percy’s hair. “Don’t tell Chris, or he’ll get a little angry.”
“Sure, killer,” Luke had said, a smile lighting up his face. He turned away from Percy to face you completely, both of his hands coming to rest on your sides. “I’ll see you at lunch?”
You saluted him seriously, but the way your other hand curled around his arm was awfully casual. “Absolutely, sir.”
He squeezed you once, sending you leaning away from his grasp. Percy felt like he was intruding on something as he watched the two of you playfully fight in front of him.
With a pointed look, Percy’d said, “Uhh. Alright. Nice to meet you?”
You at least had the shame to look a little embarrassed as you released Luke from the headlock you’d put him in. “It was nice to meet you too, Percy.” You took extra care to whack the back of Luke’s head as you left. “I’ll leave you to it!”
Luke watched you leave, a fond smile on his face as he tried to straighten out his hair. “Sorry, where were we?”
—
“What are you doing up?” you ask from across the room, keeping your voice as quiet as possible. Red Converse hit the floor softly as you make yourself comfortable in a cabin that’s definitely not yours. “It’s late. Go to sleep.”
“I thought curfew was strictly enforced here.”
“It is,” you yank your tattered hoodie over your head, dropping it onto the foot of Luke’s bed. “So keep it down before you wake up Katie. She’s snitched on me twice already.”
Percy huffs. “I’m not even—”
“S-Sorry.”
You and Percy go silent.
“It won’t… I won’t—”
“Luke,” Percy thinks he hears you say. You crouch at his side, sweeping his hair away from his face. Without even a grimace, or a sign of disgust, you wipe what must be his sweat off on your flannel pajama pants. Your voice is softened with affection. “It’s just a nightmare.”
“I won’t fail again,” he hiccups instead.
Your shoulders sag. With practiced hands, you shift the boy over and settle onto the empty part of the mattress with him.
Percy knows he’s being nosy, but curiosity keeps his eyes glued to your movements. You seem to know exactly what to do, digging through a bag at your feet and pulling out a cool water bottle. Your hands go to Luke’s shoulders as you gently coax him upwards, placing the water in his grip.
Luke’s eyes are still shut when he says, “Hey, killer.”
“Hi, hero.”
“What’re you doin’ here?”
When you don’t answer, Luke tips his head back to drink before tossing the bottle somewhere on the floor. He shifts over, giving you more room to lay down. Percy freezes when you meet his gaze head on through the darkness.
“Go to sleep,” you whisper, and Percy knows you’re not just talking to Luke.
You disappear into the mattress as Luke pulls you into a hug. Percy hears quiet rumbling as you whisper something to him, and he can’t tell which one of you pulls his head into the crook of your neck.
Luke sleeps silently for the rest of the night.
ii. now that i thought of you (things will never be the same)
Capture the Flag scares Percy to no end.
A chill goes down his spine as the other team lets out their battle cries, and he begins to doubt what Chiron said about no maiming being allowed. Some of those kids look like they’re out for blood.
The nerves only get worse as Annabeth drags him off to someplace in the woods and promptly leaves him to his own devices. No plan, no help, no sense of direction. He’s honestly expecting a bear to come out of the woods and maul him half to death, but after what feels like an hour of silence, he lounges back on a bit of rocks and watches the clouds.
“Hey, Goldilocks.”
Fear launches Percy to his feet as he takes in his surroundings. Riptide slips out of his hands and clatters onto his shield, spinning around the curved piece of metal like a Beyblade.
It’s you. Again.
“Relax,” you say quickly, raising your hands to show him you mean no harm. Your sword is tucked away and you have a slight smile on your face. “I was just going to ask you what you’re doing all alone out here. Our flag’s in the other direction, if you didn’t know.”
“I know,” Percy huffs, picking up his own weapon. He rights his armor as he looks at you suspiciously. “This girl Annabeth dragged me out here.”
“Annabeth,” you say amusedly. You glance around the two of you like she’s going to jump out of a bush.
“She’s long gone. She dragged me out here just to ditch me,” he says bitterly. “You know her?”
You have a weird smile on your face. “She’s like my little sister.”
Luke had said the same thing to him, out by the archery fields yesterday. “So you and Luke, you’re like, siblings too, then?”
“Gods, no!” you protest, your face scrunching together in disgust. “He’s just… He’s like…”
Percy watches you fumble for your words, his brow raised. You seemed pretty disgusted at his suggestion.
“He’s just Luke,” you decide on, and Percy nods, even though he doesn’t really understand. For a brief second, you look horrified again. “Did he… Say that we’re like siblings?”
“No,” he says, and watches as you smile slowly, satisfied.
Ohh, Percy wants to say. It’s like that. But he knows that you could probably tear his head off if you wanted to, so he bites his tongue.
“How long have you guys known each other?” he asks instead.
Your smile grows fond as you think about him. “Our entire lives. We were friends before either of us even knew about all of this.” You gesture to the two of you and then to the woods around you.
“That’s a long time.”
“Yeah. I couldn’t imagine this place without him,” you say thoughtfully, your gaze growing far away. “Hermes is lucky to have a son like him. He’s great.”
You talk about him so kindly. For a second, he can see his Mom in your eyes, and the adoring way she would speak about his dad on the rare occasions she would bring him up. And Percy knows it’s not nice to assume, but… He’s assuming.
Percy doesn’t phrase it like a question when he says, “You like Luke.”
A twig snaps somewhere nearby.
You’re silent for a second. “I — What do you mean?”
Percy doubles down. “You have a crush on him.”
“Alright, Goldilocks,” you say, amused. “I don’t like Luke.”
“Sure.”
“I don’t!” you insist, looking awfully embarrassed for someone who ‘definitely doesn’t like Luke.’
You turn to face the woods, and Percy has no doubt that your face is on fire.
“I thought you guys liked each other.”
“Percy, stop talking.”
“Like when you snuck into the cabin, I thought—”
“Percy,” you snap, your voice low.
“—you were dating. Like Jim and Pam. Or like Rory and Dean.”
You whirl back around, curious. “You’ve seen Gilmore Girls?”
He realizes what he said too late. “My mom made me watch it.”
Your smile disappears under your helmet as you slip it back on. “Good for her. And I’m sorry to leave you here, but I have to go.”
He frowns. “What? Why?” Percy almost doesn’t want you to leave. You’re the first person he’s seen in an hour, and your company isn’t that bad.
“My sister is about fifty feet away, and I’m supposed to be defending my flag that’s halfway across the woods.”
Percy perks up at this. “Annabeth’s back?”
Finally. He isn’t sure what she’d wanted him to do, because he definitely hasn’t done it.
You shove his shield into his hands as you brush past him. “No. Clarisse is.”
The words take a second to register, but once they do, Percy whips around in your direction. He finds nothing but the rustle of the leaves as you make your quick exit.
“Percy Jackson!” a voice booms from the direction of the woods.
He’s screwed.
iii. i once believed love would be (burnin’ red)
Their team won Capture the Flag.
Percy hadn’t done much, other than get claimed by Poseidon and be used as Clarisse bait. Nonetheless, he was enjoying the celebration feast.
Everyone was in high spirits — especially Chris, who had helped lead the team to victory while Percy was being pummeled by three angry Ares kids.
(Yeah, he was trying to not be too bitter about that.)
A group of campers were cheering on Annabeth for her plan that lead them to the big win. (Definitely not still bitter.) The comradery amongst their team was high, and even those that lost didn’t seem too angry about it.
Except for Clarisse and her cronies, of course. They were sitting in a corner, sending him furious looks every once in a while.
Percy made a mental note to ask someone about putting a deadbolt on his cabin door.
The other Ares kids didn’t seem to mind though, wearing any new battle wounds with pride. Percy could see you across the dining pavilion, talking with one of the boys from another cabin.
Luke did not look too happy about that.
Percy had thought he would be soaking up every glorious moment of the dinner, as he was the one who secured the flag for their team. But he had done nothing much other than sulk and push his food around with his fork.
“Who’s that?” Percy asks, once he notices where his angry glare is directed.
Luke is distracted when he responds. “Oh, uh.” He rubs the back of his neck. “That’s Max. Cabin 9. Hephaestus kid.”
Chris laughs as he takes his seat next to Luke, finally hungry after all of his celebrating. “He’s been trying to ask her out for a while now.”
“And he needs to take a hint.” Luke scoffs. “She clearly doesn’t like him.”
The two of you are sharing an orange. Max breaks off pieces for you to have, and Percy watches as you laugh at something he says, covering your smile with the palm of your hand.
The three of them are silent.
Percy’s head tilts. “Are you sure?”
“Yes,” Luke says, his tone steely. “She’s my… She’s my best friend. If she liked Max, she would’ve told me.”
The three of them watch as the boy stands up and you follow suit. Max tosses the rest of the orange into the fire as an offering, and the two of you head away from the celebration.
Percy gives Luke a side glance. If he had eaten anything, it probably would’ve been emptied up onto the table right now.
Luke shakes the table with the force he uses to stand up. “I’ll be back.”
His plate is left abandoned, and Chris snorts at his speedy departure. Luke’s practically jogging across the pavilion to reach you before you get too far. That old goofy cartoon running sound effect plays in Percy’s head as he does.
The boy closes the distance in record timing, stopping you and Max before you can make your way up a small hill just outside of the pavilion.
Luke must be a great liar, or just really convincing, because after a few words from him and an extended hand, you’re back at his side. You say a few parting words to Max before the two of you turn your backs on him and head back in the direction of the feast.
Unfortunately, it seems like Max is significantly unhappy with that.
He looks a little more than angry when he says something that has you and Luke whipping your heads around.
Whatever he said must not have been nice, because the next second, Luke is advancing in his direction, and the other boy is meeting him in the middle.
The small argument is beginning to attract the attention of the campers on the outskirts of the feast, with a few mixed reactions. Some look like they’re ready to jump into a brawl if need be, and others watch the argument play out, unashamed.
Percy grimaces. “Are they… okay?”
Chris gets up wordlessly to head in the direction of his friend, and Percy trails after him with not much else to do. Other campers join them, forming a bit of a crowd around the three of you.
Your voice sounds biting as you say something to the both of them, and while it seems like Max isn’t angry at you, it looks like he still spits out a snarky comment directed at Luke, if the smirk on his face says anything.
And that’s all it takes. Luke rears his arm back and strikes Max right across the face.
Something that sounds like a mix between a gasp and an “Ooh!” ripples through the crowd as he stumbles back.
That’s gotta sting, Percy thinks as Max steadies himself on shaky legs. The boy looks completely dazed from the single blow. If that’s what Luke can do with a single punch… Percy hopes he never gets on his bad side.
You shove Luke’s shoulder and say something to him, starting another disagreement between the two of you. But now steady on his feet, Max seemingly takes advantage of him being distracted and takes his own shot at Luke’s face. Percy sucks in air through his teeth as he rubs his jaw.
Luke’s on him in a second, wrestling him to the ground as he moves to probably hit him again. But you and one of the older campers rush forward to drag him off of Max just as Chiron’s booming voice sounds from the other end of the clearing.
The crowd scatters like a flock of birds. Chris drags Percy by the back of his shirt collar away from the scene, leaving you, Luke, and Max alone.
Everyone disperses back to their cabins, whispering about the events all the way up until the lights go out.
Alone in the Poseidon cabin, Percy doesn’t see the way Luke enters his own a few hours later, his knuckles sore but his heart aching.
iv. but its golden
You don’t look in Luke’s direction during Percy’s selection ceremony.
Once he’s selected Annabeth and Grover, you give him a genuine smile and squeeze his shoulder before walking away as fast as you can.
Luke calls after you, but you ignore him. The other twenty demigods at the ceremony look away in what’s probably second hand embarrassment.
Percy doesn’t see you again until much later. After knocking on his cabin door, you put a wad of cash into his hands.
“What’s this for?”
“Emergency cash,” you explain as he rifles through it. The stack is heavy. “I know Chiron gave you two hundred, but you never know. Use it only for emergencies, alright?”
“This is nearly two hundred dollars,” Percy says, shocked. “Where’d you get this from?”
“Summer job.”
“I can’t—”
“Annabeth already refused to take it from me,” you protest. “I thought you were my best bet.”
“This is a lot of money.” Percy doesn’t think he’s even held this much cash before.
“I know,” you say, before closing his fist around the money again. “But I know I could’ve really used this money on my first quest. So I’m giving it to you for yours.”
Percy was getting the impression that you weren’t going to leave his cabin with this money in your hand.
“Thanks,” he acquiesces with a smile. “Only for emergencies.”
“Only for emergencies,” you confirm, squeezing his shoulder.
“Were you nervous for your first quest?” he asks, tucking the cash into the inner pocket of his jacket.
You shake your head without an ounce of hesitation. “No. But it’s normal to be nervous, if you are.”
Percy thinks about his Mom, all alone in the Underworld. He was doing all of this for her. He was a little more than nervous.
“How were you not worried? Like at all?”
You shrug, picking at a loose thread on your hoodie. “I was with Luke. I didn’t really have anything to be worried about.”
Percy thinks about Annabeth and Grover. Could he rely on them? The Oracle’s words weigh heavy on his shoulders. Percy wished that he had someone he could count on like the way you relied on Luke.
“Are you mad at him?”
“Who said I’m mad at Luke?” You tilt your head in question.
“You ignored him in front of everyone earlier. It was kinda hard to watch.”
You look away, smiling. “Well, he was kind of being stupid last night. I’m not mad, I just needed to cool down.”
There’s shuffling in the doorway, and you don’t have to turn around to know who it is.
“Speak of the devil and he shall appear,” you mumble under your breath. Luke’s holding an old box in his hands, staring straight at the back of your head.
You give Percy one last reassuring smile. “Good luck, Percy. And I know you and Annabeth aren’t all that close, but she’s a good kid. You can count on her.”
“She’s a good kid.” Luke repeats from behind you.
You turn to face him, your gaze assessing, and Luke’s eyes widen in what Percy thinks is slight fear. But it’s like his entire body relaxes when you move forward to flick his shoulder.
“Thank you for your great input, Luke Castellan,” you tease, leaving a quick kiss on the bruise on his lower jaw.
His eyes blow wide with surprise. “Yeah,” he stammers. “Yeah.”
“See you later, hero.”
The door swings shut behind you.
Luke stares blankly for a good ten seconds before Percy speaks.
“So…” he starts. “What’s in the box?”
“Yeah, uh,” Luke repeats, dazed. “It’s a, uh. A gift.”
Percy presses his lips together, slightly miffed.
It’s obvious to him how the two of you feel about each other. He just wonders if either of you will ever figure that out yourselves.
