destabilising a narrative by means of elements embedded within the narrative itself
Skeletal narrative refers to a strategy by which Wallace embeds the seeds of textual and interpretive unraveling within the narrative voice of a story; a narrator (often but not always first-person) begins to tell a story, but through asides of tonal slippage reveals another layer of narrative under the surface, ultimately losing control of the primary narrative vocabulary and confessing or revealing what was hidden.
esp in Oblivion, Smithy, Squishy, Suffering Channel, etc. even in Rick's sections in Broom
