Also"my brother"; the little brother (the script's word); the rook-brother (the boy's picture of him)
Never seen or heard: the boy's brother exists in one comparison, Evans's rook that keeps checking ("He keeps poking you, and if you hit him, you get in trouble."), and in the boy's impression of his taunt, "I'm not touching you."
A quick sheet of the never-seen brother as the boy draws him: the blueprint rook with his orange crayon face and a finger hovering by the king ("I'm not touching you."), and a crayon portrait on school paper (about six, a hand-me-down dinosaur T-shirt, band-aids) from the lore's "for our own reference" lines. The film shows only the crayon face on the rook (E4 16:16).Placeholdermade as a quick reference, not in any episode yet, free to change.{made 2026-10-23 by lore-placeholders; not in any episode; free to change}edit
He is in the film for eight seconds and never appears. When the teacher shows Evans's desperado rook, which keeps giving check because taking it is stalemate, the boy recognises it at once from home: a brother who pokes you and gets you in trouble if you hit back. The board puts the boy's crayon face on the rook, and the boy does the voice. Two minutes later the boy finds the same idea at Board 14 himself: a rook that checks forever, which the other side can't take without stalemate. The brother taught him perpetual check before the teacher did.

IdeaFor our own reference: about six, already asleep when the lesson starts, in the room the boy shares with him. {lore crew 2026-10-22}edit
IdeaFor our own reference: he holds his finger a centimetre from his brother's arm for as long as it takes; he would be a terrifying chess player. {lore crew 2026-10-22}edit
