"Underwater"

You’ve been in camp half-blood for about two years before Luke. Showing him around when he arrived. Beaten, broken…damaged. Made him whole again with parts of yourself. Soon enough, You were one, Y/N and Luke, Luke and Y/N, one was never seen without the other, they became peas in a pod, partners in crime, Bonnie and Clyde…well…if they were they were a bunch of overpowered teenagers who are definitely way too immature for their own good.

Since then, it was always that way, you two laughing and giggling running away from head counsellors and even Chiron in some cases after causing trouble in a typical cabin 11 manner. That was until you got claimed.

You were just swimming in the lake with Luke, escaping his counsellor duties to relax. “It's nice to get away from a bunch of screaming kids once in a while huh?” You smiled, turning your head towards Luke finding him already staring at you, he returned your smile and nodded slightly “Yeah…haven’t gotten a chance to relax in a while, I miss the times when we were just two nobodies you know? Just spending everyday sparring together, having picnics together, swimming together…just being together, with no one else to burst our little bubble” He sighed, closing his eyes in comfort when he suddenly gasped, feeling a foreign grasp around his ankle “H-huh? What’s happening??” You were confused until he suddenly went under the water. Panicked, you dived under to see a water nymph pulling Luke by his ankles, his legs were flailing in panic, trying to kick the water nymph. You could see his face starting to grow pale and you felt your heart race in concern, you were swimming as fast as you could, chasing the creature when you suddenly felt yourself unconsciously speed up and you catched up to Luke and the nymph in no time. Luke was unconscious from the lack of oxygen, you grabbed him from the nymph, said creature getting scared and fleeing away. You pulled Luke up the surface, frantically swimming to shore. Panicked sobs rippin your throat at the sight of luke’s cold paling body when he suddenly sputtered awake, coughing up water as colour finally came back to his face. “Luke??? Are you alright-”” You-” He interrupted you, pointing above your head. Hanging above your head was a trident, blue and glowing.

You were shocked, appalled even, when you came to your senses and realised what it meant. You were a child of Poseidon. But it did answer many questions, how monsters would swarm you left and right, how you always felt at home in the ocean, even that one time you were “accidently” able to swim through 50 metres of water during a swimming competition without even once going up for a breath. 

You were rooted in place, body frozen, unable to move from the shock. Only turning your head when you felt Luke’s hand grabbing yours.
