“You sneaked into my cabin?”
Annabeth rolled her eyes. “Percy, you’ll be seventeen in two months. You can’t seriously be worried about getting in trouble with Coach Hedge.”
“Uh, have you seen his baseball bat?”
“Besides, Seaweed Brain, I just thought we could take a walk. We haven’t had any time to be together alone. I want to show you something—my favorite place aboard the ship.”
Percy’s pulse was still in overdrive, but it wasn’t from fear of getting in trouble. “Can I, you know, brush my teeth first?”
“You'd better,” Annabeth said. “Because I’m not kissing you until you do. And brush your hair while you’re at it.”

“Save yourselves!” Percy warned. “It is too late for us!”
Then he gasped and pointed to the spot where Frank was hiding. “Oh, no! Frank is turning into a crazy dolphin!”
Nothing happened.
“I said,” Percy repeated, “Frank is turning into a crazy dolphin!”
Frank stumbled out of nowhere, making a big show of grabbing his throat. “Oh, no,” he said, like he was reading from a teleprompter. “I am turning into a crazy dolphin.”
He began to change, his nose elongating into a snout, his skin becoming sleek and gray. He fell to the deck as a dolphin, his tail thumping against the boards.
The pirate crew disbanded in terror.”

“They had a silent staring contest, but Percy didn’t back down. When he and Annabeth started dating, his mother had drummed it into his head: It’s good manners to walk your date to the door. If that was true, it had to be good manners to walk her to the start of her epic solo death quest.”

“Whenever Percy stopped by to see [Annabeth], she was so lost in thought that the conversation went something like this:
Percy: 'Hey, how's it going?'
Annabeth: 'Uh, no thanks.'
Percy: 'Okay...have you eaten anything today?'
Annabeth: 'I think Leo is on duty. Ask him.'
Percy: 'So, my hair is on fire.'
Annabeth: 'Okay, in a while.”
