“I think it's time you met Percy. - Annabeth”

“Every single time you crossed over for me and met me on my side. I realize now, I don't think I ever met you in the middle. And I don't think I ever once said that you for that.”

“I learned a long time ago:bet against Annabeth.”

“I just don't want you to worry about me, or think you've met me, or waste your time anymore.”

“Grover: It’s a very sweet love story. I get misty-eyed every time I play it. So does Percy, but I think that’s because he’s laughing at me.”

“You think it's okay that we're eating Rudolph?"
"Dude," Percy said, "I could eat Prancer and Blitzen, too. I'm HUNGRY.”

“You are the best person I've met in years, and if I'd met you in a year's time, or maybe even a few months, I know we could be happy together, but I can't give you what you need.”

“I remembered the last time Annabeth and I had parted ways, when she'd given me a kiss for luck in Mount St. Helens. This time, all I got was the hat.”

“Every time you meet a situation you think at the time it is an impossibility and you go through the tortures of the damned, once you have met it and lived through it, you find that forever after you are freer than you were before.”

“I think of you as a friend. I used to think "friend" was just another word… Nothing more, nothing less. But when I met you, I realized what was important was the word's meaning.”
