Percy was not-so-nicely awoken by a frustrated sort of growling in his head, and it reminded him much of the way that marine creatures and equestrian animals would communicate to him. He groaned, and in his trance of sleepiness, he found himself trying his hardest to ignore it. He needed to get as much sleep as he could, after all. Today was capture the flag…
Percy’s eyes shot open and he was immediately out of bed. You idiot, Percy thought. Why would you ignore a distressed call from one of the many animals that would rely on you? He sloppily tugged on one of his several faded Camp Half-Blood tees, and a pair of navy basketball shorts. Never mind his no doubt messy hair.
Percy could still hear the distressed noises in his mind of what he assumed might’ve been a shark of some sort. But sharks actually didn’t growl, he remembered (his mind automatically knows things about animals under his Father’s domain). He frowned. Sure, some fish could make noises like that, but a fish in distress to make such noises would’ve most likely been dead at this point. He groaned in frustration as he stormed out the door of the Poseidon Cabin, filing through his mind about creature this could possibly be. A naiad? Definitely not. A siren? No way. Maybe some sort of marine mammal, like a seal? Maybe?
Percy followed the distressed noises best he could. When he went in one direction, it would get fainter. When he went another, it got louder. He followed every direction it got louder in best he could. He found himself walking along the beach the longer he followed the anxiety-ridden noises. He was still trying to figure out what this thing could possibly be.
The sand was cool against the bottoms of his feet. The sun hadn’t come up much yet. He could see it just peaking out over the horizon, barely reflecting over the waters. The tide was surprisingly aggressive this morning. He would say he was a few meters away from where the tide would normally brush, and it was lapping at his ankles from here. It was a bit of a chilly morning. So, not an overly pleasant thing to awaken to. The son of Poseidon was also a but surprised by the lack of harpies diving down to snap at him before curfew ended.
He ended up walking for a few minutes. At this point, he had kind of grown accustomed to the creature in his ear. But as he grew closer, he heard sounds of battle, almost. His brow furrowed, and he paused for a moment, listening. He was surprisingly focused in. After all, demigods, despite the most of them having the misfortune of ADHD just to help them survive, could focus very well if they really wanted to.
After a moment of listening, he quickly recognized flapping wings and furious squawks. Percy tensed. Oh, Gods. Had the harpies reached the creature first? Percy broke out into a quick run, and the scene he came upon startled him. There was a human-like being that the harpies dove at. See, the harpies were horrifying, and a absolute force of nature. But this being growled and snapped at them ferociously. At multiple points, as Percy came cautiously closer, he saw it reach up with razor sharp claws and slice at the harpies. It was tangled up in a net, too. A net? Why in the world?
Percy looked closer. It appeared to be a male? He had long, shaggy curls. Every once in a while, a harpy would reach for them, and the stranger would hiss and flail in protest. He had tanned, glossy skin, which was sliced and marred and bleeding from the harpies’ efforts to rid of him. He reached at the with menacing talons, and he would sometimes get tufts of feathers in his grasps and tear them from the harpies, causing them to squawk in agony. The farther Percy’s eyes went, the wider they grew. At the strangers waist, glossy skin slowly transformed into sleek shark skin, and Percy’s jaw dropped when he noticed the shark tail. Not only that, but there were an even number of flaps on either side of the boys’ neck that Percy recognized them as gills. And by the gods, this boy was beautiful.
Percy, after all long while of merely watching in astonishment (even though this was far from the craziest thing he head ever witnessed), finally snapped out of his trance. He speedily unsheathed Riptide from his pocket and flicked off her cap. He lunged, slicing at the harpies until they hovered far above, flapping and chirping frustratedly. After a moment of deep thought from them, they eventually squawked at each other and seemed to come to a conclusion that they should probably just give up, and flapped away.
Percy, panting faintly, looked down at the cut up… shark hybrid? He now stared up at Percy in what seemed to be awe, his mouth parted, revealing the sharp fangs that lined his gums. However, rather than being intimidated, Percy’s stomach flipped a little. He was adorable. His pupils were dilated so that he reminded him up a wide-eyed kitten.
Percy swallowed, and his Adam’s apple bobbed. “Uh… hi?” Percy’s lips quirked up a little.
The shark blinked up at him. “My Lord?” he asked.
“Uh—just, just Percy.” Percy should be used to that by now. All horses and sea creatures called him ‘my lord,’ and he still got flustered by it every time.
“…Percy.”
“Yes. Percy.” The son of Poseidon examined the shark’s wounds. “You need treated.” Percy looked back at the horizon. The Sun had risen quite a bit since he exited his cabin. The Apollo children would be working in the infirmary already. If he could just get him there…
“Can I take you to the infirmary?”
“The what?” asked the hybrid.
“The infirmary. Where you can be, like, bandaged. By other campers.”
“Other campers.”
“Yes. What, uh… what’s your name?”
“[Y/N]. Other campers?” [Y/N] repeated. “Like. Demigods?
“Yeah? Is there something wrong with that?” Percy was already in the process of picking [Y/N] up.
“Nothing. I’ve just… uhm. Oh!” [Y/N] gasped as he was scooped effortlessly into Percy’s arms, making him forget what he was going to say. His face reddened.
“You need to stop bleeding, and I don’t… have any expertise in medical, so this is your best bet.” Percy’s own face reddened as he lifted his eyes away from [Y/N]. He carried him with only slight struggle. He couldn’t imagine how many pounds that tail added onto this guy. It was big and beautiful, for sure.
The walk was fairly silent, but Percy could feel the eyes of the wounded shark hybrid stay on him essentially the entirety of the awkward trip back up the beach to the Camp Infirmary. Every once in a while, Percy would glance down to see [Y/N] looking up at him like puppy, with giant pupils. It was stupid adorable. His heart sped up excitedly every time he looked. He couldn’t help but grin a little.
Meanwhile, in his own head, [Y/N] was in awe. The Prince was carrying him, after saving him from a group of vicious harpies, to get him treated. The Prince was as beautiful as he would’ve imagined. And he was only struggling a little ([Y/N] knew that shark hybrids were fairly heavy)! How lucky was he? He was just… a lowly shark! And the Prince—oh, his mind was just going in circles. He couldn’t help it. And then he had let him call him Percy?
[Y/N] hadn’t even noticed that they were now in far more populated camp property, and there were demigods staring at him confusedly.
Percy shouldered through the infirmary door, and the stupid little restaurant-like bell rang as the door opened. He almost rolled his eyes. He was sure that it was very important or whatever, to let the know when patients arrived or whatever.
He perked a little when he saw Will peak around the corner. And then he laughed a little when he saw the son of Apollo’s jaw drop when his gaze dropped to [Y/N] in Percy’s arms.
“Percy, you’re, uhh… you’re holding a shark…man? A shark-man. Shark-guy?”
“I noticed, Will. Thanks for pointing it out. He’s really cut up. He got attacked by harpies. Help him out?”
“Oh. Yeah! Of… course? Lay him down on one of the, uh, beds.”
Percy did as instructed, and [Y/N] shifted a little uncomfortably as he was set down. He glanced from Percy to Will and around the infirmary. Percy watched him with worry (and maybe more).
Will gave Percy a look out of the corner of his eye at the way he watched [Y/N]. Then he returned to his job. He checked the sharks’ pulse, and gently treated the cuts and scratches. Every once in a while, he would glance suspiciously at Percy. [Y/N] was quiet and still. His gaze was on Will lots of the time, but it continuously started traveling to his Prince. When Will was done, he was quick to grab Percy’s wrist and drag him into a separate room, the storage.
“Uh, Will? We probably shouldn’t leave him alone—“
“Percy, you’re staring at him. With absolute heart eyes.”
Percy’s face bloomed with color. “I—no, I’m not!”
“You definitely are, dude.”
“He’s… pretty, okay?”
“Oh, he’s gorgeous. And he’s heart eyeing you back.” Will grinned a little.
“No he is not! He’s probably just, like… amazed! The sea prince is helping him, or whatever.” Percy sputtered, looking away.
Will gave him a look, like, are you serious? Percy couldn’t help but laugh a little.
“Okay, maybe, whatever. So what?”
“You guys would make an amazing couple.”
“Stop! I don’t know anything about him!”
“So? Learn.”
“Will, are you trying to matchmake here?” Percy grinned.
“You guys are soulmates. I feel it in my bones.”
“In your bones?”
“Yes. Now go seduce him. He is already in love.”
“Then why would In need to seduce him?”
“Just do it!” Will demanded, lightly shoving Percy back in the direction of [Y/N].
Percy giggled a little, but went with the momentum of the push easily. He sauntered back into the room where the shark was still laying. He was already a charmer, kind of? This should be easy. He hopes so. Percy grinned slyly as he sat in the edge of the medical bed beside the shark, and [Y/N] tensed, already reddening again. He leaned in close.
“My Prince?” asked [Y/N] meekly. He shifted his weight from one side of the bed to the other nervously, his eyes darting away.
Percy laughed softly. “I told you to call me Percy.”
At this point, [Y/N] was already lovestruck and stupid. He didn’t respond, his lips parting and closing like a confused goldfish.
“Hmmmm…” Percy thought. “What’s your favorite color?”
[Y/N] paused. “My favorite color?”
“Yeah! It can say a lot about somebody.”
“Uhm…” a smile slowly grew on the shark’s face. “Probably, like, cobalt.”
“I—“ Percy paused, confused. “Cobalt? Is that, like…”
“It’s a blue,” [Y/N] began to laugh. It was gentle and sweet and it reminded Percy of the gentle crashing of the tide against rocks.
“A blue,” whispered the son of Poseidon. His eyes softened as he looked Into [Y/N]’s eyes. He could easily picture cobalt, now.
It was a color as precious as his eyes.
