His position is that nothing within the brain's narrative generators expects, requires, or needs data from the blind spot; hence, in consciousness, the blind spot doesn't exist. No gaps need to be filled in, any more that HJPEV can be aware that Eliezer has removed a line that he might, counterfactually, have spoken.
