“Leo dropped into the pool and approched the cage. "Hola, Tia. Little bit of trouble?"
She [Hera] crossed her arms and sighed in exasperation. "Don't inspect me like I'm one of your machines, Leo Valdez. Get me out of here!”

“Leo had seen Tia Callida in action; she liked knives, snakes and putting babies in roaring fires. Yeah, definitely let's unleash her rage. Great idea.”

“Frank didn’t drop you on purpose,” she said. “He’s not like that. He’s just a little clumsy sometimes.”

“Oops,” Leo said, in his best Frank Zhang voice. “Dropped Leo into a squad of enemy soldiers. Dang it!”

“Leo,” Hazel gasped, “I can’t—my arms—”
“Hazel,” he said. “Do you trust me?”
“No!”
“Me neither,” Leo admitted.”

“Correct." Kekrops sounded bitter, like he regretted his decision. "My people were the original Athenians--the gemini."
"Like your zodiac sign?" Percy asked. "I'm a Leo."
"No, stupid," Leo said. "I'm a Leo. You're a Percy.”

“Also … the plan sounded exactly like the sneaky, twisted, ridiculously annoying and noble sort of thing Leo Valdez would do.”

“She reached into her coat pocket and felt two things she hadn't expected…. One was a wad of cash… she brought out the money. Leo whistled. "Allowance? Piper, your mom rocks!”

“Is that me?,' Leo said. 'Like me--having this dream--looking at me having a dream?”

“Gaea?” Leo shook his head. “Isn’t that Mother Nature? She’s supposed to have, like, flowers in her hair and birds singing around her and dear and rabbits doing her laundry.”
“Leo, that’s Snow White,” Piper said.”

“Tell me about our legal issues. And use small words. I don't like to think at this hour of the morning. It hurts."
