In book one, page 32, we meet our Mr. Morton of the story, Max-Ernest. With spiky hair, a pimple on his nose, horrible friends (Cass, Yo-Yoji), and a huge voice, Max-Ernest is probably the least social person in his school. This is mainly because of his knowledge of riddles and smart personality, to which his classmates are jealous, I assume. Let's review, shall we?
Book One: In this book, Max-Ernest is lonely, our Norman Babcock oof the book. Resembling the boy himself, but having a role of Mr. Morton, Max-Ernest didn't have any friends at all, even until he met Cass, who considered the two to be survivalists: just that. Sounds very Iago, doesn't it? Max-Ernest, having saved the ignorantly mean girl from a burning fire, also makes a joke about her in the end. But instead of following the Lilo and Stitch plot, Cass goes for a more bratty role, which is pretending she likes him, but really doesn't. Now, if Max-Ernest wasn't so nice, he would have went for the Rudolph plot. You know, Hermey running away fROM the Elf Center, etc. But that wasn't all. Hermey, having found his friends and family were more important than being a hero (to which he really is, defeating the abdominable snow monster), returns to his village. Max-Ernest should've went Kratos and barraged her, but didn't.
Books 2 and 3: Max-Ernest is now friends with Cass, unfortunately, but Cass is still harsh to him, as well as everyone else. His classmates, watching his performance at the Talents Show, are jealous that Yo-Yoji isn't performing, to which they don't even answer his jokes, except his parents (which is an obvious reference to "only your mother could love it".).
Book 5: I won't waste my breath here, so I'll just say Cass and Yo-Yoji are jerks and assholes.
