(The committed Ch. 487 reader-note’s Calico Yorki And The Infected Half Vanish Into The Calm Belt basename is the un-reconciled variant of this same beat.)*
The seed
The payoff
(Forward / unresolved — out of the 0468–0507 window. Yorki and the infected half vanish into the Calm Belt; their end is deliberately unshown. Left pending.)
Why this matters
A negative-space seed: Oda stages a captain’s farewell, has the two ships drift apart, and then declines to depict the captain’s death — the classic Oda tell that an “off-page” fate is being kept in reserve. The open questions: does Yorki’s plague-ship become the ghost ship Brook later drifts on, or does the healthy half’s “new ship” meet that end?
