A lot of people are reading this, but not reviewing, so please do!
This chapter you'll meet Mark again, as we definitely need some character development for him. Calypso describes him as a nice guy but in the first chapter he was a jerk to Leo. So who is he? What's his story? Well read and find out! :) Enjoy!

Leo stared after Calypso, hurt. He was about to say the most important three words in his life, and she runs away? Wasn't this the kind of stuff girls waited for their whole lives?

He sat down with his head in his hands. Maybe...maybe Calypso didn't really like him. Or was she just playing hard to get? Girls are so confusing, he thought.

A few feet away, Mark stood, watching him. He shook his head and walked over.

Leo looked up, and upon seeing Mark, halfheartedly snarled "What do you want?"

Mark sighed. "Leo...I really think it's best if you go home now."

Leo's eyes widened. He stood up angrily."Who are you to make that decision for me? You have no idea what I've gone through to come here! You have no idea what this means to me...what Calypso means to me..." His anger turned into sorrow with his words.

Mark glared at him, "What, you think that I don't love Calypso just as much? Maybe more? I chose to stay here! No one else, not even you, stayed with her. I was the only one!"

Leo glared back, "Just because I left doesn't mean I didn't love her! I had to freaking save my friends, and guess what, the whole world! If I hadn't left, then this whole world would be freaking destroyed, including Ogygia, and everyone would have died!

"I had people back home too! I left my two best friends, my mother and my sister! Yesterday they held a funeral for me! Do you know what it's like, to have everyone you love think you're dead?" With every word Mark revealed more and more passion until his face turned read, his eyes rimmed with tears.

Leo looked away guiltily. "Why'd you stay then?" he asked in a small voice.

Mark looked up into the sky. "Like I said, I love Calypso. Besides, I wasn't really needed back home."

"What do you mean?"

Mark sighed. "It's a long story."

Leo settled down. "I'm listening." And he was, for once, waiting patiently even with his ADHD.

Mark glanced down at his hands, spreading them out as he began speaking. "Well, you already know I'm a son of Apollo. Monsters didn't pay much attention to me, I guess I wasn't that important. So I stayed at home, went to a mortal school and hung out with mortal friends. I knew that I was different, that I was a half-blood, but my mom never really mentioned it. And that was okay with me." Mark's eyes grew distant as his memories surrounded him. Memories that he had been keeping back for so long, but now welcomed.

Leo waited for a bit then nudged him. "Mark?"

Mark started, then continued, his eyes still slightly dreamy. "Right. Well, everything was okay until my mom got married. Don't get me wrong, Dave's a great guy. But after they had my little sister Viria, they were their own family, yknow? Especially because I was the threat that brought monsters knocking on our door. And the reason that Viria spent a month in the hospital. After that, I left. I didn't want to hurt them anymore."

His mind traveled back to the day a hellhound attacked. He had been too late. The monster struck Viria, and she landed with a painful thud. In a short minute he shot an arrow at its heart, but Viria was on the ground, completely still. While his wounds were healed quickly with some ambrosia and nectar, Viria was left with a broken arm with bruises and scratches all over. He would never forget the look his mother gave him. She never said it out loud but he knew she and Dave both blamed him. They refused to let Mark heal her and instead called 911.

One night, while visiting his little sister, he decided to leave. He kissed her one last time and whispered a good bye, then packed his things at home, and left. It was hard, but he knew it was the best thing for his family. And he didn't feel like he belonged anymore.

"Where'd you go? To Camp?" Leo broke into his nostalgia.

Mark shook his head. "I didn't even know about Camp until I met Taya-"

Leo interrupted, he couldn't help it. "Taya?"

Mark waved his hand impatiently. "I was getting to that. It was, oh, maybe two weeks after I left? I ran into this girl, literally." He could remember the exact moment they had met, what she looked like, and every detail of the following days. But Leo didn't need to know all that. "I found out that she was a demigod, daughter of Athena. We started traveling and living together, and naturally I fell in love with her. Although I didn't tell her for a long time. She told me about Camp Half-Blood, but we never made it."

"Why not?"

Mark shrugged. "We didn't know exactly where it was. Plus we were attacked by monsters a lot. This one time I thought I was nearly done for, but this random kid jumps out of nowhere and saves me. He introduced himself as Phillip, son of Hermes. So our little trio continued on our way to Camp Half-Blood. We were nearly half-way there when I decided to tell Taya how I felt." Mark chuckled dryly. "Didn't end too well, at least on my part. She told me that she was sorry but she liked Phillip. And the next day they got together and all that. It was okay, I mean we were still best friends. But I felt more and more like a third wheel. "

Leo snorted. "Try being a seventh wheel and getting rejected by every girl you talk to."

Mark looked surprised. "Huh? Really?"

Leo nodded ruefully. "Well my two best friends got together, then we met up with two other couples and went around saving the world, the three dream teams and Leo. As for getting rejected, well I'm not a typical hero. I'm the joker, the Hephaestus kid that's good with tools, the guy no one really takes seriously. Every girl I've approached either liked someone else or just didn't think I was good enough."

Mark put one hand on Leo's shoulder. "Sounds rough. Guess we're more alike than I thought."

Leo gave a hint of a smile. "So how'd you get here then?"

Mark dropped his hand and continued. "We ran into one ambush too many, and I fell unconscious. Next thing I knew, I was here. I met Calypso and it felt like all the pieces came together and I could be happy with a girl I loved. I didn't mean to be so rude when you came. I just wanted to spare Calypso the heartbreak, but I guess it's really her choice, right?"

"Yeah..." Leo trailed off. He knew it wasn't fair to be mad at Mark for falling in love with Calypso, or mad at Calypso for falling in love with Mark.

Leo suppressed a sigh. Why does everything have to be so complicated? It wasn't like he could even hate Mark, and he didn't want to seem really possessive of Calypso. I have no more right than he does, really.

Leo smiled, trying his best not to let Mark see how frustrated he was, even though he was pretty sure Mark knew and felt it too.

"Well, for now, we might as well make the best of being marooned. Might as well make the best of it, right? I, for one, have always wanted to try surfing and this is an island," Leo winked, trying his best to lighten the mood.

Mark laughed, though it sounded a bit forced. "You came to the right place. I happen to be a pretty good surfer myself."

A/N: So how was it? Too much dialogue? Good ending or no? Sorry. I would have made this longer except I didn't want to keep you guys waiting!
I actually had this crazy idea to make Mark Percy in disguise and stuff, but I think I would have gotten destroyed by die-hard Percabeth fans :P Might make that a crackfic though...
The next chapter will be up when I get 10 reviews! So please review and as always, concrit is very welcome! Please tell me what you think about Mark and his story in your review :)
