In the middle of the night, Tessa flinched awake. She nuzzled into Percy's chest and sighed. His arms were carefully wrapped around her and their legs mixed together perfectly. Then she felt pain.

Agonisingly sharp, burning pain.

Instantly Percy was awake, and shouting, "Will! Get your sunny ass in here!"

Will stumbled out of the other room; blonde hair a mess, and his bright blue eyes were laden with sleep. "What's wrong?"

"What do you fucking think Will? She's in pain!" Percy growled.

"Percy, we can't give her anymore nectar or ambrosia. If we do she'll burn up and die. Make her comfortable and help her fall back asleep." Will ordered, shuffling back into the room to cuddle Nico.

Percy sighed a soft "Damnit".

He carefully moved Tessa so her torso was flush against his, and Tessa stared up at him curiously. Tessa splayed her fingers against his chest and started to trace letters until he understood.

"Why are you doing this?"

"Because you needed medical help, Tess." He said softly.

"You could have left me as soon as I had help." She pointed out.

"I feel like a... bond or something. I don't know what how to explain it. It's like I've know you my whole life. Somehow I know where you would hide from me, your favorite colour, book, and song. I just know." Percy struggled to explain.

"Sing to me?"

"Ok. I'll warn you I'm terrible." Percy chuckled when Tessa rolled her eyes.

Percy started to sing, "Someone's always coming around here, trailing some new kill. Says I see your picture on a hundred dollar bill. What's a game of chance to you win this one, of real skill. So glad to meet you, Angeles."

"Picking up the tickets shows there's money to be made. Don't wanna lose the gamble, that's the history of the trade. Did you add up all the cards left to play? To zero." Percy's voice was a deep, rich, smooth baritone, and it made Tessa shiver.

Percy pulled Tessa closer and sang, "And sign up with evil, Angeles. Don't stop me, trying now. Oh, oh. Cause I'm all over it, Angeles. I can make you satisfied in, everything you do."

It was kinda sexy, Tessa thought.

"All your secret wishes could arise, and be coming true!
Spend forvever, with my poison arms around you. No one's gonna fool around with us. No one's gonna fool around with us."

"So glad to meet you, Angeles." He finished, singing the ending softly.

Tessa nuzzled Percy and he sighed contentedly before tightening his grip on Tessa. "Sleep now my Tessa. I will be there to protect you whilst you sleep."

Tessa shyly cuddled into him and Percy buried his face in her hair and inhaled deeply. Tess smelled like the woods, dogs, metal, and the dark. She smelled like how Percy imagined home smelled like. Sure, Percy could visit his mom, but that wasn't where he considered his home anymore. Home was Tessa now.

Percy knows all about soul mates and bonds. Because Percy was the son of the sea, he could find his soul mate by smelling them, as odd as it sounds. The sniff Percy just took of Tessa confirmed it.

Percy's underlying scent helps confirm it too. It smells of the woods, dogs, metal and the sea. There is usually one differentiating scent that leads them to their soul mate if they are a child of the sea.

But Percy was worried. Did she know that she was his and he was hers? Was she going to reject him? But Percy soon fell asleep yet again.

Tessa wasn't truly asleep. She was curled into Percy. As the child of the night she could find her soul mate by hearing them sing. For a child of the night their soul mate's voice will blend perfectly with theirs.

Tessa knew all good and well that Percy was hers, and she was his. But did he know? She too soon fell into a deep slumber.
