In Ch. 331 (“The Big Argument”), after the Galley-La Company verdict condemns the Going Merry and Luffy decides to switch ships, Usopp — unable to accept abandoning the ship that carried the crew “over every wave, in every battle” — fuses his grief with a confession of inadequacy and quits the crew, then challenges his captain to a duel over the Merry.
The payoff
(Forward-payoff beyond this note’s seeded beat: Usopp’s reinvention behind the Sogeking mask, his King of Snipers / God Usopp identity, the Enies Lobby reunion, and the Going Merry’s eventual proper farewell/funeral — all ~Ch. 0376+. (MERGE note: the parallel reader-proposed seed “Usopp Departs The Crew After Losing The Duel For The Going Merry” — predicted_reveal: Usopp’s departure is not permanent; he returns via Sogeking without surrendering his pride, the crew is reunited at Enies Lobby, and the abandoned Going Merry gets a proper farewell — was consolidated into this note rather than forked.))

Why this matters
Oda’s dialogue-tell / parallel-arc-structure technique: the rupture is staged as an explicit, self-articulated confession of inadequacy rather than mere anger over the ship. The Merry-attachment seeded since the Ch. 0254 secret-repair beat and the Ch. 0303 “patchwork repairs” defensiveness, and the shame-fuse of the @0328–0329 Franky-Family humiliation, pay off here into open conflict — a current crew bond tested to breaking (the rare counter-beat to the recruitment pattern), which feeds Usopp’s forward reinvention.
