Gately, the wraith, and the figurants — "He says Wraiths by and large…"
He says Wraiths by and large exist (putting his arms out slowly and making little quotation-mark finger-wiggles as he said exist) in a totally different Heisenbergian dimension of rate-change and time-passage. As an example, he goes on, normal animate men’s actions and motions look, to a wraith, to be occurring at about the rate a clock’s hour-hand moves, and are just about as interesting to look at.
Context
Wraith-time: the dead run so fast the living are hour-hands. This is the rule that makes the wraith's months of stillness a real sacrifice, and it explains the "way too fast to see" swarms Gately imagines in scene 169 — plus note that even the wraith finger-wiggles scare-quotes around exist.
