Clears lungs

Piper pulled Jason closer and kissed him.
"I love you," she said.
The words just poured out of her, like the water from the cornucopia. She couldn't tell what his reaction was, because then they were underwater.
She held her breath. The current roared in her ears. Bubbles swirled around her. Light still rippled through the room, and Piper was surprised she could see it. Was the water getting clearer?
Her lungs were about to burst, but Piper poured her last energy into the cornucopia. Water continued to stream out, though there was no room for more. Would the walls crack under the pressure?


With a cry of alarm, Piper realized that Percy's and Jason's faces were still underwater. She hoisted them up. Instantly, Percy gulped and began to thrash, but Jason was as lifeless as a rag doll.
Piper clung to him. She yelled his name, shook him, and slapped his face. She barely noticed when all the water had drained away and left them on the damp floor.
"Jason!" She tried desperately to think. Should she turn him on his side? Slap his back?
"Piper," Percy said, "I can help."
He knelt next to her and touched Jason's forehead. Water gushed from Jason's mouth. His eyes flew open, and a clap of thunder threw Percy and Piper backward.


Percy grinned. "In case you're wondering, that was clean water in your lungs. I could make it come out with no problem."
