“ Percy: Put your cap back on... get out! Annabeth: What? No! I'm not leaving you. Percy: I've got a plan. I'll distract them. You can use the metal spider... maybe it'll lead you back to Hephaestus. You have to tell him what's going on. Annabeth: But you'll be killed! Percy: I'll be fine. Besides, we've got no choice. Annabeth glared at me like she was going to punch me, and then she did something that surprised me even more she kissed me. Annabeth Be careful, Seaweed Brain. Percy: she put on her hat and vanished. ”
