"Hey, Emerald! I got a letter from Cooper!" "Who is that?" "The guy from Halfmoon. He says that I am the savior!" This is so exciting! I can't believe that Cooper sent me a letter! And I am the Savior? People always said that when I was a kid but now Cooper said it! I wonder if I get a gold crown. I might try to find it but probably not. Maybe if I don't even try or if I give up they will be angry at me. Maybe I should try to get it.
