MS-1993's title page carries a margin note already sketching DMZ's effects: "no speech--Death[.] See Wraith & Gately."

This is planned-but-unwritten material: it appears in outline or margin notes but was never drafted as a scene.

In the published book. This material does not appear in the published book.

Evidence. A single source reports this. Documented by Steven Moore's first-draft collation.

Bears on. This difference bears on the following open questions: did Hal ingest DMZ, and by what route (dosed / endogenous / self / none); is the wraith real (vs. Gately's fever); does Gately survive the hospital / what the beach scene is.

Further notes. Links DMZ → mutism → the Wraith/Gately nexus in Wallace's own planning hand, before the YG frame existed.
