“Thalia's shoulders relaxed. "I owe you one.""Two.""One and a half," Thalia said.She smiled, and for a second, I remembered that I actually liked her when she wasn't yelling at me.”
“Thalia blushed. "Hi, Lord Apollo."Zeus's girl, yes? Makes you my half sister. Used to be a tree, didn't you? Glad you're back. I hate it when pretty girls turn into trees. Man, I remember one time—”
“Jason muttered "And I saw something...Really terrible.""That was Hera," Thalia grumbled, "Her Majesty, the Loose Cannon.""That's it, Thalia Grace," Said the goddess. "I will turn you into and aardvark, so help me-" "Stop it, you two," Piper said. Amazingly, they both shut up.”
“You sure about this?" I asked Thalia. She turned to me. "Amaltheia leads me to good things. The last time she appeared, she led me to you."The compliment warmed me like a cup of hot chocolate. I'm a sucker that way. Thalia can flash those blue eyes, give me one kind word, and she can get me to do pretty much whatever.”
“Argh!" Thalia pushed me, and a shock went through my body that blew me backward ten feet into the water. Some of the campers gasped. A couple of the Hunters stifled laughs."Sorry!" Thalia said, turning pale. "I didn't mean to—"Anger roared in my ears. A wave erupted from the creek, blasting into Thalia's face and dousing her from head to toe.I stood up. "Yeah," I growled. "I didn't mean to, either."Thalia was breathing heavily."Enough!" Chiron ordered.But Thalia held out her spear. "You want some, Seaweed Brain?"Somehow, it was okay when Annabeth called me that — at least, I'd gotten used to it — but hearing it from Thalia was not cool."Bring it on, Pinecone Face!”
“They both (Thalia and Hera) glared at her, and for three long seconds, Piper wasn’t sure which one of them was going to kill her first.”
