Which of the boys seems to have the strongest attachment to Percival? Please provide some evidence in your answer.

While all the boys show a certain appreciation and awe for Percival, Neville is clearly the one most fascinated with him. This is evidenced most directly by the way his monologue describes how he moves, ostensibly to attend to an itch, merely so he can catch a glimpse of Percival. It is also safe to infer at this point, that Neville has a strong attraction to Percival. While Louis and Bernard seem to admire Percival the way a younger brother admires his older brother, Neville's emotions seem to tend more towards an erotic love rather than a filial love.
