Percy watched silently as Leo and Frank strategized. They seemed to be arguing about some subject or another, but he didn't know what. And at the moment he didn't particularly care. His head was hurting again.

"There's 100% no way off the island?" Leo asked Calypso again. She shook her head and he made a sound of annoyance before turning back to Frank. "We have to have a way of contacting her-"

"I doubt the barrier will allow you to." Percy chimed in.

They looked at him.

"There's a barrier around the island, yes? The island is meant to be a prison, it probably keeps all messages that are sent inside of it." He shrugged.

Leo groaned. "But we gotta get out! We told Reyna we'd signal her once we found you!"

"Leo, that's obviously not gonna work. We have to think of something else." Frank said reasonably.

Calypso grumbled something and stalked off.

"What's wrong with her?" Leo asked.

"She doesn't like it when people leave. She can't, and she hates that other people who show up here can leave eventually while she has to stay for her immortal life." Percy explained quietly.

"Oh."

"Has she told you how other people get off the island?" Frank asked.

Percy shook his head. "I don't think she wants to. She doesn't want me to leave. I think it was a perfect situation for her when I showed up, a man with no memories who might stay with her because he doesn't remember anything to go back to.... but then I started remembering things. Now she has no hope again."

The three glanced at each other, silent for a few moments.

"What if we promised to come back for her?"

Percy shrugged. "No man finds Ogygia twice. I doubt she would believe you, if you could even conceive a way to return."

"What if we sacrificed to the gods!" Leo suggested.

"With what sacrifice?" Frank snorted.

"You can do a bull, can't you?"

"You are not sacrificing me to the gods!"

"Okay, fine! But the idea still stands. Do we have anything remotely valuable we could sacrifice?"

"Not that I know of." Frank sighed. "Cap'n, is there anything on the island that could do the trick?"

Percy didn't answer for a few seconds, then he started a little. "Oh, you were talking to me."

"Yes I was, Cap'n." Frank looked at him. "I'm sure it's hard to remember you're a captain when you don't have many memories."

He shrugged and glanced in the direction Calypso had gone. "I can't think of anything valuable enough to the gods that we would be able to get ourselves and Calypso out of here. As far as I can tell, she's basically a godly prisoner from the war against the Titans. They're not going to want to let her go, they'll be afraid that she'll turn against them if she's given the chance."

"Surely not all the gods believe that." Frank said indignantly.

"I don't pretend to know the minds of the gods. Especially not the airheaded ones." Percy looked up at the sky. Thunder rumbled and he rolled his eyes. "That one especially."

Leo tugged on his hair, trying to think of any other possibilities. "What about Nico?"

"What about him?" Frank asked.

Percy stayed silent. He could remember some things about Nico, but not much.

"Think he could do that thing he can do with shadows and get us?"

"Doubtful." Frank shook his head.

Leo growled in annoyance and kept thinking.

As the two crew-mates continued to suggest things back and forth, Percy walked down to the edge of the water again. He crouched and ran his fingers through the gentle waves hitting the sand, frowning and thinking.

"Cap'n?" They'd finally noticed that he'd walked away. Percy didn't answer.

Frank and Leo exchanged a glance before walking towards him slowly. They stood on either side of him silently, wondering what he was thinking as he gazed out at his father's domain.

Percy stood suddenly, a trail of water stretching from his fingers to the water. For a few moments his hand filled with more water until he had a sphere slightly larger than his head. Percy stared at it for a moment and it reformed into a javelin-shaped object. He took two steps back and wound up, hurling it out over the water as hard as he could.

The three of them watched as it soared away, then suddenly it seemed to hit something solid. It dropped into the water again.

Percy nodded as if this confirmed his theory and started back up the beach.

Frank and Leo frowned at each other and scrambled after him. "Cap'n! What was that?"

"A hunch." Percy answered, heading for Calypso's hut. "Come on, we should help Calypso with the food. It's nearly time for lunch."

Leo and Frank exchanged another glance, the smaller boy giving a helpless shrug and the taller sighing inaudibly. Then they followed their captain dutifully into the hut.
