„Dude.” Jason gave Percy a bear hug.”Back from Tartarus!” Leo whooped. “That’s my peeps!“

— Rick Riordan
„Like your zodiac sign? Percy asked. 'I'm a Leo.'No, stupid,' Leo said. I'm a Leo. You're a Percy.“
— Rick Riordan
„Just curious how much I'm going for these days," Leo said. "I mean, I can understand not being as pricey as Percy or Jason, maybe… but am I worth, like, two Franks, or three Franks?“
— Rick Riordan
„No!" Leo yelled."Uhhh," Nico groaned from the floor."Piper!" Jason cried."Monkey!" Frank yelled."Not monkeys," Hazel grumbled. "I think those are dwarfs.""Stealing my stuff!" Leo yelled, and ran for the stairs.“
— Rick Riordan
„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.“
— Rick Riordan
„Nike could start you two fighting easily.” Percy gave her a sideways smile. “Yeah, we can’t have another incident like in Kansas. I might kill my bro Jason.” “Or I might kill my bro Percy,” Jason said amiably. “Which proves my point,” Annabeth said.“
— Rick Riordan
„Nothing?" Favonius cried. "The one you care for most… plunged into Tartarus, and you still will not allow the truth?"Suddenly Jason felt like he was eavedropping.“
— Rick Riordan
„Leo,” Jason said, “you’re weird.”“Yeah, you tell me that a lot.” Leo grinned. “But if you don’t remember me, that means I can reuse all my old jokes…!“
— Rick Riordan
„Now… well, after what happened in Tartarus, it seemed like Percy had graduated to a totally different level of butt-kickery.“
— Rick Riordan
„Run!” Piper said.“We are running!” Jason picked up the speed.“Run better!” Leo shouted.“
— Rick Riordan
„Entertain me, heroes of Olympus. Give me a reason to do more."Bacchus to Percy and Jason“
— Rick Riordan
„Huh," said Percy. "Never seen Jason fly before. He looks like a blond superman.“
— Rick Riordan
„The only thing they had in common was Calypso, and every time Leo thought about that he wanted to punch Percy in the face.“
— Rick Riordan
„Forget the chicken-nugget smoke screen. Percy wanted Leo to invent an anti-dream hat.“
— Rick Riordan
„Too bad Jason wasn’t a metal automaton. At least then Leo would have some idea of how to help his best friend. But with humans … Leo felt helpless. They broke way too easily.“
— Rick Riordan
„you know festus means happy in Latin right? You want us to go save the world on Happy the dragon?"-Jason to Leo in the lost hero“
— Rick Riordan
„Percy: I thought I’d lost my mom forever, and I was stuck on a hill in a thunderstorm fighting this huge bull dude while Grover was passed out wailing. “Food!” It was terrifying, man.“
