Family Feud

In this book, the egos are kinda like Thomas Sander's sides in the way that they represent different parts of Jack (I'm putting this in the description to make the book easier to understand):

Robbie-represents his child like nature

JJ-represents his creativity

Chase-represents his caring

Marvin-represents his belief in good

Schneep-represents his want to help

Anti-represents his depression/anxiety

Jackaboy Man-represents his positivity
