And it's in the blood of a hero

To know where he goes he may never return yeah

This is why we do it this is worth the pain

This is why we bow down and get back up again

This is where the heart lies, this is from above

"Why?" Nico asked. Percy looked over at his cousin from his bed. The Ghost King was sitting cross-legged on the floor staring at his older cousin. He dropped by the night before saying that they had to talk about something important but he never got around to actually doing it.

"Why what?" Percy asked, confused at the sudden question.

"Why do we fight for the Olympians?" he asked again. "All they've ever brought us is pain. So why do you do this? Why do you let yourself be used as a pawn in this war?" Percy adjusted himself so he was leaning against his headboard and his cousin was in his line of sight. He stared at Nico's dark eyes and saw nothing but honest curiosity. He sighed and ran his hand through his hair, a nervous habit he picked up recently. The question got him thinking. Why did he?

"Nico… I think… I don't…" He tried to explain, he really did, but how could he explain something he himself didn't know? He sighed again and stared at his ceiling hoping that the racked plaster would provide him with answers. "I.. Because it's the right thing to do, Nico." He finally said.

"Is it really? How do we know that this is the right thing to do? Is it enough for you?" Nico asked.

Percy thought about why he did his best in quests. He thought of his mom, the best person in the world. He thought about his friends, Annabeth, Grover, Nico, Thalia. He thought about his kind-of family, Poseidon, Chiron, everybody in camp. He thought about disobeying Chiron's orders most of the time. The reason why he accepted his first quest, the reason why he sneaked out of camp to save it, the reason why he went and saved Annabeth even if he was told not to, the reason why he accepted his most recent quest despite its dangers. It was there all along and he was just too blind to see it, maybe, it just wasn't expressed enough.

He remembered how it felt to lose his mom, how it felt when he finally saw her again. He remembered how scared he was when he saw Thalia's poisoned tree. He remembered how heartbroken he was when Annabeth fell down the cliff. He remembered how it felt when he finally saw her, battered and bruised. He remembered how happy he feels whenever he's with his family, both immediate and extended. He remembered how proud his father was when he retrieved Zeus' lightning bolt, how depressed Mr. D was when his son, Castor, died, how desperate Hermes was – is – to bring Luke back. He remembered all of those and realized that maybe, just maybe, everybody just have to look a little deeper to see it.

"It should be." Percy said. "But it's not, at least for me it's not. There's something else there that helps me, that pushes everyone just a bit more." Nico looked at him, dark eyes betraying nothing but curiosity.

"What is it, Percy?" he asked, eyebrows furrowed. Percy looked at his cousin; a smile that could rival the sun god's lit up his face.

"Love." He said simply.

Love is this, this is love

Love is why we do it love is worth the pain

Love is why we fall down, get back up again

Love is where the heart lies love is from above

Love is this, this is love

A/N: It's short, but I couldn't help but right it. :) Anyway, if you're reading my other story Junior Year, I'm sorry I haven't updated. I'll probably update next week. No promises though. :)

The song is This is Love by The Script. I love that band. :) I also love the song. Listen to it.
