Sometimes Percy forgets he and Jason come from too different worlds.
Percy: Easy Jason, it's alright if you mess up.
Jason: No, it's alright if you mess up. If I mess up I've failed, and I fail I might as well be dead.
Percy: I think you're taking this a bit too far.
Jason: Percy you could trip over your own feet and at least five people would stop to help you up. When you fall people catch you.
Jason: What about me? If I did that I'd be thrown away like a used rag.
Percy: Jase that's not true.
Jason: Your camp would never think to replace you. Your friends would scour the earth and the underworld to find you.
Percy: They didn't look for you?
Jason: No, they replaced me with you. Your camp loves you for who you are. If I'm not the perfect son of Jupiter...Than I might as well not exist at all.
