“This is so cool!" Nico said, jumping up and down in the driver's seat. "Is this really the sun? I thought Helios and Selene were the sun and moon gods. How come sometimes it's them and sometimes it's you and Artemis?"
"Downsizing," Apollo said. "The Romans started it. They couldn't afford all those temple sacrifices, so they laid off Helios and Selene and folded their duties into our job descriptions. My sis got the moon. I got the sun. It was pretty annoying at first, but at least I got this cool car."
"But how does it work?" Nico asked. "I thought the sun was a big fiery ball of gas!"
Apollo chuckled and ruffled Nico's hair. "That rumor probably got started because Artemis used to call me a big fiery ball of gas.”

“I … what? Why would you want a son of Hades in the same room with people you’re trying to heal? Why would anyone want that?’
‘You can’t help out a friend? Maybe cut bandages? Bring me a soda or a snack? Or just a simple How’s it going, Will? You don’t think I could stand to see a friendly face?’

“For a long time,’ Nico said, ‘I had a crush on you. I just wanted you to know.’ Percy looked at Nico. Then at Annabeth, as if to check that he’d heard correctly. Then back at Nico.

‘You –’

‘Yeah,’ Nico said. ‘You’re a great person. But I’m over that. I’m happy for you guys.’

‘You … so you mean –’

‘Right.’

Annabeth’s grey eyes started to sparkle. She gave Nico a sideways smile.

‘Wait,’ Percy said. ‘So you mean –’

‘Right,’ Nico said again. ‘But it’s cool. We’re cool. I mean, I see now … you’re cute, but you’re not my type.’

‘I’m not your type … Wait. So –’

‘See you around, Percy,’ Nico said.”
