Percy didn't get it. Ever since he'd come back from Tartarus, Leo had been acting weird around him. It was almost like he was angry at him, though Percy didn't know what he had done wrong. Leo avoided Percy, barely spoke to him, and shot him glares out of nowhere. Percy decided it was time to get to the bottom of this.

He pulled Piper aside after dinner. "Hey, um I've noticed that Leo has been really weird around me and it's almost like he's avoiding me and I don't really-"

"Percy." Piper gave him a look. "Leo met Calypso."

"Oh." Percy said. "Oh"

"Yeah. It was hard on him, I can tell. He's really heartbroken."

Piper could probably sense that, being the daughter of the love goddess and all.

Percy shook his head, sitting down next to Piper. "I had no idea."

It made sense. Leo had been moody lately, not making as many jokes. He had met Calypso and fallen in love with her, and Calypso had fallen in love with him too. Percy sat down, a wave of guilt washing over him.

"I feel terrible." He said. "I haven't thought about her in so long. I spent two weeks with Calypso. She was good to me, nursed me back to health. She's beautiful and an amazing person but..."

"You weren't in love with her."

Pecy shook his head. "Annabeth and I... well I don't really know what we were, but I knew that I liked her then. I didn't even realize that Calypso felt that way until I left."

Piper pursed her lips. "He'll get over it Percy, just give him time."

Percy sighed. "He's right to be mad at me. The Olympians aren't good at keeping promises. I should've checked in with them and made sure that they released her."

"You're not the one to blame Percy. The Olympians should've kept their promise. To be completely honest though, I think that Leo feels kind of threatened."

"Threatened?" Percy asked, clearly confused.

Piper rolled her eyes. "Yes, threatened. How would you feel knowing that the girl you're in love with used to be in love with one of your friends."

"Yeah okay, you're right. I should talk to him about it."

"Yeah you definitely should."

Percy got up to leave but stopped. "Hey, how did you hear about me and Calypso anyway?"

Piper shrugged. "Word got around at camp. Trust me, everyone knows."

"I am going to kill Annabeth." He muttered.

A/N: By the way, these chapters aren't in any particular order. I'm just kind of jumping around between the books.
