“Bianca di Angelo shivered. "That explains Nico, you remember last summer, those guys
who tried to attack us in the alley in DC?"
"And that bus driver," Nico said. "The one with the ram's horns. I *told* you that was real.”

“He’s a restless soul, always looking for another chance to drive,’ Nico said. ‘The last few years, he’s been my driver whenever I need one.’
‘You have a zombie chauffeur,’ Leila said.”

“Who wants us?" Bianca demanded. "Because if you think you'll get a ransom, you're wrong. We don't have any family. Nico and I—" Her voice broke a little. "We've got no one but each other.”

“Whoa," said Nico as he climbed off the bus. "Is that a climbing wall?"
"Yeah," I (Percy) said.
"Why is there lava pouring down it?"
"Little extra challenge…" - Percy”

“This is my driver,’ Nico said. ‘Jules-Albert finished first in the Paris–Rouen motorcar race back in 1895, but he wasn’t awarded the prize because his steam car used a stoker.”

“He [Nico] regarded Jason, as if waiting for an attack. 'If the others found out-'
'If the others found out,' Jason said, 'You'd have that many more people to back you up, and to unleash the fury of the gods on anybody who gives you trouble.”

“Bus driver, bus driver, the sirens have gone,
The bombs may come down, but the buses go on;
Bus driver, I know you won't think me a snob
If I whisper: "Bus driver, I don't want your job."”

“Nico leaned over and plucked a grape. Probably that was the guy’s entire diet for the day.”

“In other words, Bush broke what I have always called the “Amish bus driver” rule. If your religion requires you not to drive, cool beans, free country — but then you can‘t get hired to be a bus driver if your religion won‘t let you drive the bus.”

“I don’t mind authority, but not authoritarian authority. After all, the bus driver is allowed to be the boss of the bus. But if he’s bad at driving, he’s not going to be a bus driver anymore.”
