The wraith's plan was to interface with Hal through Ortho Stice
Where readers stand
minority
In plain terms: the wraith's plan was to reach Hal by working through his teammate Ortho Stice.
Where the text lands: that an interface with Stice is underway is genuinely unresolved (and depends on accepting the wraith reading); that it is specifically aimed at Hal is a stretch; and the question looks built to be unanswerable. Among readers: a minority reading -- but with the corpus's best manuscript-to-text evidence chain.
An early draft made Stice a wraith-figure outright, and the text gives the wraith a need for a physical opening plus the built-up, never-resolved Hal-Stice contest. No page states the plan, and the attribution's load-bearing step is an inference. See Ghosts and Wraiths.
The question
This reading answers the crux the wraith's use of Ortho Stice (draft "Wraithster").
The ruling
Weighed in the adversarial ledger The Wraith, Stice, and Lyle.
The evidence
the wraith's need for a physical hole (Gately's wound; the Papineau coffin-holes story); the heavily built-up-and-withheld Hal–Stice contest as kept scaffolding of a cut resolution
