Brooks Bones Refrain Foreshadows His Living-Skeleton Fate

The seed
A retro-seed: the orphan Brook (@1184, ~70 yrs before present) sings “we’re all bones when we die / cows and frogs and slaves and kings / that’s all there is to say,” a class-collapsing memento-mori refrain born of slum starvation in Esperia’s Cello Port. The song is also the chapter title (“We’re All Bones When We Die”).
The payoff
Why this matters
A song planted decades in-story before the fruit that literalizes it, revealed to readers decades of publication after the payoff — Oda’s habit of retro-fitting a character’s oldest, most incidental line into their defining trait. The thematic image (memento mori, “kings and slaves alike are bones”) is the seed; the Devil-Fruit transformation is the payoff.
