Does Jaws read slow too or is it only spoken word that troubles him?
His lacking speed makes him especially frustrated when he can’t understand the jokes in his joke books within seconds, or when he’s looking through a book about astronomy/math/science/physics and he doesn’t instantly wrap his head around what it is in front of him. Even when no one is pressuring him to understand things with the same speed he had before the accident - it still really bothers him when he can’t.
… But hey, because of this he’s got an excellent memory! Though it might take him a while to understand something new, once he wraps his mind around it he will likely never forget it! I mean, he blows right through fluffy bunny when he reads it to Sugar (Pretty much all from memory, honestly he only really needs the book so he can show Pap’s the pictures), and with all the goofy voices too! So its a “you win some, you lose some” situation.
