“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.”

“He had no idea where the stereotype of dumb giggly blondes came from. Ever since he'd met Annabeth at the Grand Canyon last winter,when she'd marched toward him with that Give me Percy Jackson or I’ll kill you expression, Leo had thought of blondes as much too smart and much too dangerous.”

“Very slowly using two fingers, Annabeth drew her dagger. Instead of dropping it, she tossed it as far as she could into the water.

Octavian made a squeaking sound. "What was that for? I didn't say toss it! That could've been evidence. Or spoils of war!"

Annabeth tried for a dumb-blonde smile, like: Oh, silly me. Nobody who knew her would have been fooled. But Octavian seemed to buy it. He huffed in exasperation.

"You other two..." He pointed his blade a Hazel and Piper. "Put your weapons on the dock. No funny bus--"

All around the Romans, Charleston Harbor erupted like a Las Vegas fountain putting on a show. When the wall of seawater subsided, the three Romans were in the bay, spluttering and frantically trying to stay afloat in their armor. Percy stood on the dock, holding Annabeth's dagger.

"You dropped this," he said, totally poker-faced.”

“And,” Annabeth continued, “it reminds me how long we’ve known each other. We were twelve, Percy. Can you believe that?”
“No, he admitted. “So…you knew you liked me from that moment?”
She smirked. “I hated you at first. You annoyed me. Then I tolerated you for a few years. Then—”
“Okay, fine.”
She leaned in and kissed: him a good, proper kiss without anyone watching—no Romans anywhere, no screaming satyr chaperones.
She pulled away. “I missed you, Percy.”
Percy wanted to tell her the same thing, but it seemed too small a comment. While he had been on the Roman side, he’d kept himself alive almost solely by thinking of Annabeth. I missed you didn’t really cover that.”
