The reverse hierarchy
As Jason descends the ladder of popularity in Maggot, he begins to describe the world of being bullied. It is evident that there are rules for those at the bottom, just like the ones Jason described as the beginning of the book from the top. The politics of middle school go on.
Like with being popular, Jason is also completely aware of the situation of bullying and he clearly already knows how to act. He knows the rules. He repeats the advice he picks up for the reader at various points. The way to be a good victim is the be passive and not react. he demonstrates this when they yell at him, give him the wedgie, and when Ross tries to talk to him. We all know this strategy, but the his level of awareness of it at this age is what is impressive. It is also representative of how everything Jason does is edited and is working towards his self image, even while at the bottom.
The other aspect of the beginning of the book that outlines the hierarchy of the school is when Jason outlines which group he is in. This is reflected in Maggot when he explicitly joins the table filled with “lepers”. These guys are just as cohesive as Spooks, and also have a set of requirements to join, albeit unfortunate requirements. The people that Jason joins at the bottom are just as refined as those at the top. For example, Dean is trained to not even flinch when hit with the chip. He has become a master of nonviolence.
All of this shows how the hierarchy is not triangular, but rather a diamond that has rules governing throughout and how you act determines is always important.
