I am curious how he reads this book then 

okay i have this theory that Scout has dyslexia or some reading disorder. on past comics (forget which ones) it shows him reading fine but when we get to comic #6 he’s struggling.

i dunno, man. it’s just a thought ¯\_(ツ)_/¯

Or maybe it was because he was hit on the head with a heavy crate falling from an airplane.
