“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.”

“The eidolons started pounding on the door.
'Who is it?' Leo called.
'Valdez!'
'Valdez who?”

“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.”

“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.”
