AN: So, we know that Calypso's curse says that every generation someone would arrive to her island that she wouldn't be able to keep from loving and they'd inevitably have to leave. That leaves a lot of room for wiggle room for how it could look. Thus, Calypso getting an adopted child since the love of a parent and child is still love.

More than one way to love (first look)

-Calypso-

Walking the shores of her lake, Calypso stared at the stars reflected in the perfectly flat surface of the water. She always knew when she'd be getting her next visitor, could feel their imminent arrival, and could tell that the next being she would be unable to keep from loving would soon arrive.

And, like always, she couldn't help but feel the surge of hope that maybe, just maybe, this one would be different.

A cry roused her from her thoughts as she saw a shape washed up along the shore. Hurrying to the sound that was unusual for Ogyia, she found a dead woman having washed ashore, clutching a baby boy who was crying out for his mother to wake up.

"Oh gods." She breathed in horrified pity as she picked up the crying baby who latched on to her, the little infant's right arm covered in glistening rictal lightning burns. The eyes, sea green, and the nature of the scars told her a great deal of just who this child must be.

Glancing back down at the dead woman, Calypso gently closed her eyes "I promise…I will look after your son." She swore to the corpse, having noticed the similarities in the shape of the eyes and the nose to the baby now in her arms.

Rocking the baby to sleep, she called her spirits to help her. She had to bury the woman who'd died trying to protect her child, a child that was now hers to raise.

To love.

Checking the infant's clothes, she found a name stitched into the shirt.

"Perseus."

-Zeus-

"I know you stole it Poseidon!" Zeus raged, fist clenching in desire for a bolt that was gone, stolen by his brother.

"And I told you I didn't do it!" Poseidon snapped back, "We cannot steal the symbol of power of another god, remember?"

"But our children aren't bound by such laws." Zeus snarled, "I know your bastard is still alive." He'd tried ensuring the bastard was properly judged after his lightning struck at the bastard sea spawn and its mother on the beach but only the mother ever reached Hades' kingdom.

"He is alive, but he could not have stolen your bolt." Poseidon shook his head, a genuinely startling amount of grief and sadness in the sea god's eyes "Not…not where he is now."

"Where he is?" Hermes looked up confused, the god of travelers clearly wondering where they could be that would be so important.

Poseidon sighed at the question, but looked up "Perseus washed ashore of Ogygia as an infant after Zeus, the so called 'god of Justice' murdered his mother."

"But…Calypso's curse…" Ares balked, looking genuinely nauseous.

"There is more than one love Ares." Aphrodite spoke up, glancing at Poseidon "I would assume she has been raising your son as her own?"

"She loves him as if he were her own child." Poseidon admitted "I have watched them from a distance, and sent what gifts for my child I could, but have not seen him. I followed your precious 'laws' brother." Poseidon glared at Zeus who flinched despite himself.

"He will be taken to camp regardless." Zeus scowled, willing to admit that perhaps the bastard wasn't the lightning thief, but the boy was still a threat.

-Perseus-

"No!" Perseus cried out, clutching at his mother's dress as she sobbed just as hard, clutching at him desperately even as the War god pulled him away uncaringly. His mother's dress tore under his grip, a large strip coming free, held tightly in his hand as Ares pulled him up and flashed away with him, Percy's last sight being his mother's crying face as she reached out for him.

As the light faded, Percy found himself on a grassy hill overlooking a collection of cabins and a large house.

"Stop crying brat." Ares scowled, throwing Percy down into the dirt, uncaring of what the cruel god had done before they flashed away.

Tears still falling, Percy tied the strip from his mother's dress around his wrist. Zeus had murdered his birth mother, had taken him from his second mother Calypso and Ares had gleefully carried out the deed.

Percy was going to do everything in his power to see them pay, and to see his mother freed.

This, he swore upon the Styx.
