Along with Percival, Johnny is the smallest of the littluns.
He is described as “sturdy and fair” (p.13), “built… with a natural belligerence” (p.62) which he soon shows by throwing sand in Percival's face after he had finally stopped crying (causing him to start again!).
Later, Johnny is shown crying when he thinks Eric may be bleeding from his encounter with Jack's fire stealers. Â
